The seat 5 can be slid while the storage box 11 is secured below.

Further, since the front slide mechanism 20 and the rear slide mechanism 21 are provided between the seat 5 and the inner cover 18, these slide mechanisms 20 and 21 are hidden by the inner cover 18 when the baggage enters and leaves the storage box 11. (FIG. 6). For this reason, the appearance of the vehicle is not spoiled even when luggage is put in or out.

Further, since the inner cover 18 completely covers the opening 15 of the large storage box 11, the area is formed large, and the front slide mechanism 20 and the rear slide mechanism 21 are installed on the upper surface of the inner cover 18. The degree of freedom of the installation positions of the slide mechanisms 20 and 21 can be increased. In particular, since the interval between the two rear slide mechanisms 21 can be set large, the seat 5 does not rattle in the width direction of the vehicle, and the stability of the seat 5 can be improved. At the same time, since one front slide mechanism 20 is provided on the front side of the inner cover 18, the widths of the front portions of the inner cover 18 and the seat 5 can be reduced, and the rider's feet can be improved.

In the slide mechanism, one front slide mechanism 20 is provided at the front of the inner cover 18 and two rear slide mechanisms 21 are provided at the rear, so that one seat lock mechanism is provided for this one front slide mechanism 20. If 33 is installed, the slide of the seat can be locked stably. In other words, if the slide mechanism is only two rear slide mechanisms 21 arranged in parallel, twisting will occur unless the lock mechanism 33 is installed in each slide mechanism 21,
Since one front slide mechanism 20 is installed in addition to the two rear slide mechanisms 21 arranged in parallel, if one seat lock mechanism 33 is installed on this front slide mechanism 20, twisting does not occur. . As described above, according to this embodiment, the seat lock mechanism 33 can function stably, and the number of the seat lock mechanisms 33 can be reduced, so that the cost can be reduced.

Further, since the operating handle 32 of the slide lock rod 29 is provided in front of the seat 5 and between the legs of the rider sitting on the seat 5, it is easy to apply force when moving the seat 5.

Moreover, since the operating handle 32 is in the vertical position shown in FIG. 1 by the urging force of the return spring 40 when the seat lock mechanism 33 is locked, it does not interfere with the rider's feet.

Further, since the operating handle 32 is located in front of the seat 5 and the operating direction of the operating handle 32 matches the sliding direction of the front slide mechanism 20 and the rear slide mechanism 21, the operating handle 32 is operated when the operating handle 32 is operated. Slide lock rod 29 and front guide rail 27 of slide mechanism 20
Further, no excessive force acts on the rear slide rail 25 and the rear guide rail 26 of the rear slide mechanism 21, and the operability is improved.

In the above embodiment, the slide mechanisms 20 and 21 cover the opening 15 of the storage box 11 with the inner cover 18 and the seat bottom plate.
Although the one disposed between the rear body 7 and the seat bottom plate 22 is described above, the storage box 11 is installed in the rear body 7, and the slide mechanisms 20 and 21 are disposed between the upper surface of the rear body 7 and the seat bottom plate 22. May be done.
