Accordingly, the luggage cargos 20 having different height dimensions can be stacked in the upper-lower direction by engaging with the base member 30 and the luggage cargo 20 below, so that the luggage cargos 20 having different height dimensions can be stacked on the base member 30 while being combined with a high degree of freedom in the upper-lower direction, without moving relative to the base member 30 or the luggage cargo 20 below.

As illustrated in FIG. 3, the plurality of panel members 40 are coupled in the upper-lower direction at the rear end of the base member 30. The plurality of panel members 40 include first panel members 41 and second panel members 42. The first panel members 41 and the second panel members 42 are substantially rectangular members extending in the upper-lower direction and the left-right direction with a predetermined thickness in the front-rear direction. In the present embodiment, the first panel members 41 and the second panel members 42 have the same size. The first panel members 41 and the second panel members 42 have a height dimension of three times the unit height dimension H1, that is, 3×H1. Accordingly, the height dimensions of the first panel member 41 and the second panel member 42 are the same as the height dimension of the first luggage cargos 21. The first panel members 41 and the second panel members 42 have a width dimension of about twice the width dimension W1, and have a width dimension W4 substantially equal to the width dimension W3. A first panel member 41 is coupled to the base member 30 while being placed at the rear end of the upper surface 30a of the base member 30. A second panel member 42 can be detachably coupled to a first panel member 41 or a different second panel member 42 in the upper-lower direction.

The upper ends of the left and right side surfaces of the first panel member 41 and the second panel member 42 are each provided with a claw 40a. The lower ends of left and right side surfaces of the second panel member 42 are each provided with a fastening lever 40b engageable with the claw 40a. The tightening lever 40b of the second panel member 42 engages with the claw 40a of a first panel member 41 or a second panel member 42 arranged below the second panel member 42. Accordingly, the second panel member 42 is coupled to the first panel member 41 or the second panel member 42 arranged below the second panel member 42 in the upper-lower direction. FIG. 3 illustrates an example in which a second panel member 42 is coupled to the upper surface of a first panel member 41, and a different second panel member 42 is coupled to the upper surface of the second panel member 42. In this way, in FIG. 3, the three panel members 40, specifically, the one first panel member 41 and the two second panel members 42 are coupled in the upper-lower direction.

The upper surfaces of the first panel member 41 and the second panel member 42 are each provided with an upper surface connector 40c, and the lower surface of the second panel member 42 is provided with a lower surface connector 40d that can be conducted to the upper surface connector 40c. If the second panel member 42 is coupled to the upper side of a first panel member 41 or a different second panel member 42, the lower surface connector 40d is conducted to the upper surface connector 40c of the first panel member 41 or the second panel member 42 arranged below the second panel member 42. Thus, a plurality of panel members 40 coupled in the upper-lower direction at the rear end of the base member 30 are electrically connected to each other.

The upper surface connector 40c of the panel member 40 arranged at the uppermost stage has a cap CP fitted thereto. The cap CP can prevent foreign matters such as water or dust from entering the upper surface connector 40c of the panel member 40 arranged at the uppermost stage, and can prevent the upper surface connector 40c of the panel member 40 arranged at the uppermost stage from being conducted to an unintended member.

As illustrated in (a) of FIG. 6, the panel members 40 are each provided with a panel-side connector 400. The panel-side connector 400 includes a pedestal 400a, a connector terminal 400b fixed to the pedestal 400a so as to face forward, and a pair of left and right positioning pins 400c fixed to the pedestal 400a so as to face forward with the connector terminal 400b interposed therebetween in the left-right direction. The pedestal 400a is supported on the panel member 40 by a pair of left and right coil springs 400d. The front surface of the panel member 40 is open in a region overlapping the connector terminal 400b and the positioning pins 400c when viewed in the front-rear direction. Accordingly, the panel-side connector 400 is provided on the panel member 40 such that the connector terminal 400b and the positioning pins 400c can be accessed from the front of the panel member 40.

As illustrated in (b) of FIG. 6, the rear surface of each luggage cargo 20 is provided with a luggage cargo-side connector 200 that can be conducted to the panel-side connector 400 of the panel member 40. The luggage cargo-side connector 200 includes a connector terminal 200a fixed to the rear surface of the luggage cargo 20 so as to face rearward, and a pair of left and right bushes 200b fixed to the rear surface of the luggage cargo 20 so as to face rearward with the connector terminal 200a interposed therebetween in the left-right direction. The bushes 200b have a shape that can be fitted to the positioning pins 400c of the panel-side connector 400.

As illustrated in (c) of FIG. 6, the luggage cargo-side connector 200 of each of the luggage cargos 20 is coupled to the panel-side connector 400 such that the positioning pins 400c of the panel-side connector 400 and the bushes 200b are fitted to each other, so that the connector terminal 200a of the luggage cargo-side connector 200 and the connector terminal 400b of the panel-side connector 400 are coupled to each other and the luggage cargo-side connector 200 is conducted to the panel-side connector 400. At this time, the pair of left and right coil springs 400d provided on the panel member 40 absorb dimensional errors of the luggage cargos 20 and the panel members 40, assembly errors of the plurality of panel members 40, rattling between the engagement rails 51 and the legs 52, and the like. Therefore, it is possible to connect the luggage cargo-side connector 200 of each luggage cargo 20 to the panel-side connector 400 in a reliably conducted state.

As illustrated in FIGS. 3 and 9, if the luggage cargo 20 is stacked on the upper surface 30a of the base member 30 by the legs 52 of the luggage cargo 20 engaging with the engagement rails 51 provided on the upper surface 30a of the base member 30, the luggage cargo-side connector 200 is provided at a first distance L1 above the upper surface 30a of the base member 30 in the upper-lower direction. Accordingly, in the present embodiment, the luggage cargo-side connector 200 is provided at the first distance L1 above the lower end of the luggage cargo 20, that is, the lower ends of the legs 52 in the upper-lower direction. The luggage cargo-side connector 200 is provided at a second distance L2 from the left surface of the luggage cargo 20 in the left-right direction.

Each first panel member 41 is provided with four panel-side connectors 400. Similarly to the first panel member 41, each second panel member 42 is provided with four panel-side connectors 400.

The panel-side connectors 400 provided on the first panel member 41 includes a panel-side upper left connector 401a provided on the upper left region of the front surface of the first panel member 41, a panel-side lower left connector 401b provided in the lower left region of the front surface of the first panel member 41, a panel-side upper right connector 401c provided in the upper right region of the front surface of the first panel member 41, and a panel-side lower right connector 401d provided in the lower right region of the front surface of the first panel member 41.

If the first panel member 41 is coupled to the base member 30, the panel-side lower left connector 401b and the panel-side lower right connector 401d are provided at the first distance L1 above the upper surface 30a of the base member 30 in the upper-lower direction. Accordingly, in the present embodiment, the panel-side lower left connector 401b and the panel-side lower right connector 401d are provided at the first distance L1 above the lower surface of the first panel member 41 in the upper-lower direction. If the first panel member 41 is coupled to the base member 30, the panel-side lower left connector 401b is provided at a position offset leftward by a third distance L3 in the left-right direction from the middle point between the left engagement rail 51 and right engagement rail 51 of the pair of left and right engagement rails 51 provided in the left region of the upper surface 30a of the base member 30. If the first panel member 41 is coupled to the base member 30, the panel-side lower right connector 401d is provided at a position offset leftward by the third distance L3 in the left-right direction from the middle point between the left engagement rail 51 and the right engagement rail 51 of the pair of left and right engagement rails 51 provided in the right region of the upper surface 30a of the base member 30.

The third distance L3 is a distance at which, if the first luggage cargo 21 and the second luggage cargo 22 are stacked on the upper surface 30a of the base member 30 by the left and right legs 52 engaging with the pair of left and right engagement rails 51 provided in the left region of the upper surface 30a of the base member 30 while the first panel member 41 is coupled to the base member 30, the panel-side lower left connector 401b is coupled to the luggage cargo-side connectors 200 of the first luggage cargo 21 and the second luggage cargo 22. Similarly, the third distance L3 is a distance at which, if the first luggage cargo 21 and the second luggage cargo 22 are stacked on the upper surface 30a of the base member 30 by the left and right legs 52 engaging with the pair of left and right engagement rails 51 provided in the right region of the upper surface 30a of the base member 30 while the first panel member 41 is coupled to the base member 30, the panel-side lower right connector 401d is coupled to the luggage cargo-side connectors 200 of the first luggage cargo 21 and the second luggage cargo 22.
