Claims
- 1. A bearing apparatus for a driven shaft of an automobile, comprising:
- a cylindrical outside member adapted to be mounted to a chassis of the automobile in surrounding relation to the driven shaft;
- a cylindrical inside member mounted concentrically within said cylindrical outside member and adapted to be fixed for rotation with the driven shaft;
- means, comprising rolling elements, for rotatably mounting said cylindrical inside member within said cylindrical outside member for rotation relative to said cylindrical outside member;
- a circular detected member fixed to said cylindrical inside member for rotation therewith about an axis and having a plurality of projections spaced evenly apart in a circumferential direction of said circular detected member; and
- a unitary member including a substantially cylindrical cover which has a free end provided with an opening in a position offset relative to a center of said free end of said cylindrical cover, which is connected to said cylindrical outside member so as to cover at least parts of said circular detected member, and which has a predetermined diameter, a rotational speed detector mounted and disposed within said opening so that a central axis of said rotational speed detector is substantially coextensive with a central axis of said opening and so as to be positioned opposite from said plurality of projections of said circular detected member and including means for detecting rotational speed of said circular detected member and for generating a rotational speed signal indicative of the rotational speed of the driven shaft, an integrally molded resin block having an L shape, one end of the resin block being fixed to said cover about said opening and fixed to said rotational speed detector, and the other end of said resin block being disposed in a space resulting from a dimensional difference between a dimension of said rotational speed detector and said predetermined diameter of said cylindrical cover so that said other end of said resin block is inside an outer circumference of said cylindrical cover, and a connector means molded integrally with said other end of said molded resin block for detechably connecting said rotational speed detector electrically to a plug of a system which will utilize said rotational speed signal, said connector means extending away from said rotational speed detector in a direction normal to said axis about which said circular detected member is rotatable.
- 2. A bearing apparatus as recited in claim 1, wherein
- said connector means includes a recessed connector housing and a pair of electrical terminals mounted therein.
- 3. A bearing apparatus as recited in claim 1, wherein said cover includes an annular flange formed about said opening for uniting said molded resin block with said cover.
- 4. A bearing apparatus as recited in claim 3, wherein
- said annular flange is formed integrally with said cover.
- 5. A bearing apparatus as recited in claim 3, wherein
- said annular flange includes a knurled portion for making positive connection with said molded resin block.
- 6. A bearing apparatus as recited in claim 5, wherein
- said rotational speed detector includes a first end extending inwardly of said cover and a second end extending outwardly of said cover and united with said molded resin block, said second end of said rotational speed detector having a knurled portion for making a positive connection with said molded resin block.
- 7. A bearing apparatus as recited in claim 1, wherein
- said plurality of projections of said circular detected member face in an axial direction of said circular detected member.
- 8. A bearing apparatus as recited in claim 1, wherein
- said rotational speed detector includes a main body disposed in and coaxially with said opening, and a detector portion extending away from and coaxially with said main body.
