Axis-direction gap S22 with a predetermined width is provided between surface 62a and surface 241a.


Next, exemplary first radial-direction elastic member 70 will be described with reference to FIGS. 1 and 2. FIG. 2 is a perspective view illustrating exemplary first radial-direction elastic member 70.


First radial-direction elastic member 70 is placed in radial-direction gap S11 with a predetermined width. First radial-direction elastic member 70 is formed by a rectangular metal plate with resilience. The metal plate has rectangular slits 70D that are long in the short side direction of the metal plate, and slits 70D are arranged parallel to each other in the long side direction at constant intervals. This forms a plurality of rectangular spring plates 70A with one ends connected to connecting strip 70B and the other ends connected to another connecting strip 70B. The longitudinal central area of each spring plate 70A is press-formed so as to have a curved projection on the same one side relative to the surface of the original metal plate. Spring plates 70A are rounded so that the longitudinal central area of each spring plate 70A is convex outward in the radial direction and both ends 70E and 70F of the metal plate in the long side direction are adjacent to each other, and this results in a cylindrical spring. In the cylindrical spring, connecting strips 70B act as fulcrums of spring plates 70A at both ends, and the longitudinal central areas of spring plates 70A act as the points of action.


First radial-direction elastic member 70 is set so that its smallest inner diameter (inner diameter of connecting strip 70B) is smaller than the outer diameter of first cylindrical section 41 in the free state. Thus, when first radial-direction elastic member 70 is mounted on first cylindrical section 41, gap 70C between both ends 70E and 70F of the metal plate in the long side direction spreads against the resilience, and first radial-direction elastic member 70 is held in first cylindrical section 41 by the resilience. In this state, the largest outer diameter of first radial-direction elastic member 70 (outer diameter in the longitudinal central areas of spring plates 70A) is set to be larger than the diameter of first hole 14.


When outer operating shaft 40 with first radial-direction elastic member 70 mounted is inserted into first hole 14, spring plates 70A are pressed by the inner circumferential surface of first hole 14, and the height of spring plates 70A in the radial direction decreases inward in the radial direction. Outer operating shaft 40 rotates with first radial-direction elastic member 70, and first radial-direction elastic member 70 slides and rotates against the inner circumferential surface of first hole 14. Accordingly, outer operating shaft 40 receives frictional resistance from the inner circumferential surface of first hole 14 via first radial-direction elastic member 70, thereby acquiring torque required for the rotation operation.


Next, second radial-direction elastic member 80 will be described with reference to FIGS. 1 and 2. Second radial-direction elastic member 80 is a shared component commonly used as first radial-direction elastic member 70. The reason why the shared component is used is that the shapes of radial-direction gap S21 and radial-direction gap S11 are set to the same size, as described above. Note that second radial-direction elastic member 80 will be described using the same reference signs as those for first radial-direction elastic member 70.


Second radial-direction elastic member 80 is placed in radial-direction gap S21 with a predetermined width. Second radial-direction elastic member 80 is set so that its smallest inner diameter (inner diameter of connecting strip 70B) is smaller than the outer diameter of second cylindrical section 61 in the free state. Thus, when second radial-direction elastic member 80 is mounted on second cylindrical section 61, gap 70C between both ends 70E and 70F of the metal plate in the long side direction spreads against the resilience, and second radial-direction elastic member 80 is held in second cylindrical section 61 by the resilience. In this state, the largest outer diameter of second radial-direction elastic member 80 (outer diameter in the longitudinal central areas of spring plates 70A) is set to be larger than the diameter of second hole 24.


Rotating body 60 rotates integrally with inner operating shaft 50 by fitting over rotation prevention section 53 of inner operating shaft 50. Second radial-direction elastic member 80 is mounted on second cylindrical section 61 of rotating body 60 as described above. When rotating body 60 with second radial-direction elastic member 80 mounted is inserted into second hole 24, spring plates 70A are pressed by the inner circumferential surface of second hole 24, and the height of spring plates 70A in the radial direction decreases inward in the radial direction. Inner operating shaft 50, which rotates integrally with rotating body 60, rotates with second radial-direction elastic member 80, and second radial-direction elastic member 80 slides and rotates against the inner circumferential surface of second hole 24. Accordingly, inner operating shaft 50 (rotating body 60) receives frictional resistance from the inner circumferential surface of second hole 24 via second radial-direction elastic member 80, thereby acquiring torque required for the rotation operation.


Next, first axis-direction elastic member 91 will be described with reference to FIG. 1. First axis-direction elastic member 91 is, for example, a spring washer that is put in axis-direction gap S12 in a flexed state against the resilience. Outer operating shaft 40 slides and rotates against first axis-direction elastic member 91. Accordingly, outer operating shaft 40 receives frictional resistance from first axis-direction elastic member 91, thereby acquiring torque required for the rotation operation.


Next, second axis-direction elastic member 92 will be described with reference to FIG. 1. Second axis-direction elastic member 92 is a shared component commonly used as first axis-direction elastic member 91. The reason why the shared component is used is that the widths of axis-direction gap S21 and axis-direction gap S22 are set to be the same. Second axis-direction elastic member 92 is put in axis-direction gap S22 in a flexed state against the resilience. Rotating body 60, which rotates integrally with inner operating shaft 50, slides and rotates against second axis-direction elastic member 92. Accordingly, inner operating shaft 50 (rotating body 60) receives frictional resistance from second axis-direction elastic member 92, thereby acquiring torque required for the rotation operation. Note that, in order to improve the operability, it is preferable that the operation torque of inner operating shaft 50 and the operation torque of outer operating shaft 40 are within a predetermined range.


Incidentally, axis-direction gap S22 varies due to a factor such as a dimensional tolerance of a component. With large axis-direction gap S22, the frictional resistance from second axis-direction elastic member 92 decreases and the operation torque of inner operating shaft 50 decreases. With small axis-direction gap S22, the frictional resistance from second axis-direction elastic member 92 increases and the operation torque of inner operating shaft 50 increases. The variation in axis-direction gap S22 sometimes causes the operation torque of inner operating shaft 50 to fall outside the predetermined range.


Torque adjusting member 100 is placed in an axis-direction gap between axis-direction one-side end surface 62b of second large-diameter cylindrical section 62 and axis-direction the-other-side end surface 311a of housing 311, and adjusts the operation torque of inner operating shaft 50. Torque adjusting member 100 is a washer, for example. The operation torque of inner operating shaft 50 is adjusted by selectively using a washer that fits the axis-direction gap among a plurality of types of washers with different plate thicknesses.


Rotationally operated electronic component 1 according to the above embodiment includes: first block body 10 that is placed on one side of an axis direction and includes first hole 14; second block body 20 that is placed on another side of the axis direction and includes second hole 24; outer operating shaft 40 that includes first cylindrical section 41 fitting within first hole 14 to rotate about an axis; inner operating shaft 50 that extends in the axis direction, penetrates through first cylindrical section 41 and second hole 24, and fits within first cylindrical section 41 to rotate about the axis; rotating body 60 that includes second cylindrical section 61 fitting over inner operating shaft 50 to rotate integrally with inner operating shaft 50 and fitting within second hole 24 to rotate about the axis; first radial-direction elastic member 70 that is put, in a flexed state against resilience, in radial-direction gap S11 between an inner circumferential surface of first hole 14 and an outer circumferential surface of first cylindrical section 41; and second radial-direction elastic member 80 that is put, in a flexed state against resilience, in radial-direction gap S21 between an inner circumferential surface of second hole 24 and an outer circumferential surface of second cylindrical section 61.


With the above configuration, when outer operating shaft 40 is rotated, it receives frictional resistance from the inner circumferential surface of first hole 14 via first radial-direction elastic member 70, thereby acquiring torque required for the rotation operation. In addition, when inner operating shaft 50 is rotated, it receives frictional resistance from the inner circumferential surface of second hole 24 via second radial-direction elastic member 80, thereby acquiring torque required for the rotation operation. In such a manner, both of the two shafts (outer operating shaft 40 and inner operating shaft 50) can acquire constant high operation torque.


Rotationally operated electronic component 1 according to the above embodiment further includes: first axis-direction elastic member 91 that is put in axis-direction gap S12 in a flexed state against the resilience; and second axis-direction elastic member 92 that is put in axis-direction gap S22 in a flexed state against the resilience. This allows both of the two shafts to acquire higher operation torque.


Further, rotationally operated electronic component 1 according to the above embodiment includes a washer (torque adjusting member) that is placed in the axis-direction gap between second large-diameter cylindrical section 62 and housing 311 and adjusts the operation torque of the inner operating shaft. This allows the operation torque of inner operating shaft 50 to be adjusted by selectively using a washer that fits the above axis-direction gap among a plurality of types of washers with different plate thicknesses.


Next, variations of rotationally operated electronic component 1 according to the above embodiment will be described with reference to FIGS. 3A and 3B. The description of the variations is mainly about configurations different from those in the above embodiment. The same reference signs are given to the same configurations, and descriptions thereof are omitted. Note that axis-direction gap S22 is highlighted in variation 1 illustrated in FIG. 3A and variation 2 illustrated in FIG. 3B.


In variation 2, the operation torque of inner operating shaft 50 is adjusted without using a washer (torque adjusting member).


The reason why axis-direction gap S22 is large as illustrated in FIG. 3A is that, for example, when the operation torque of inner operating shaft 50 is larger than the operation torque of outer operating shaft 40 and exceeds a predetermined range, rotating body 60 including second large-diameter cylindrical section 62 with thinner plate is selected, for example, to make axis-direction gap S22 larger than a standard width, so that the operation torque of inner operating shaft 50 is reduced and fallen within the predetermined range.


The reason why axis-direction gap S22 is small as illustrated in FIG. 3B is that, for example, when the operation torque of inner operating shaft 50 is smaller than the operation torque of outer operating shaft 40 and below a predetermined range, rotating body 60 including second large-diameter cylindrical section 62 with thicker plate is selected, for example, to make axis-direction gap S22 smaller than a standard width, so that the operation torque of inner operating shaft 50 is increased and fallen within the predetermined range.


According to the above variations, for example, it is possible to adjust the operation torque of inner operating shaft 50 by selectively using suitable rotating body 60 from a plurality of types of rotating bodies 60 including second large-diameter cylindrical sections 62 with different plate thicknesses.


The all of the above embodiments are merely examples to implement the present invention, and the technical scope of the present invention should not be interpreted as limited by these embodiments. In other words, the present invention can be implemented in various forms without departing from the gist or main features thereof.


In the above embodiments, rotationally operated electronic component 1 is provided with both first and second axis-direction elastic members 91 and 92, but the present invention is not limited to this, and rotationally operated electronic component 1 needs to be provided with either one of first and second axis-direction elastic members 91 and 92, for example, or may be provided with neither of first and second axis-direction elastic members 91 and 92 because adequate operation torque can be acquired by first and second radial-direction elastic members 70 and 80, for example.
