Then, after inserting the end portion of the lever member 20 on the wall side into the insertion portion 13 of the support body 10, the end portion of the lever member 20 is positioned so as to be surely locked to the stopper portion 12 of the support body 10. The lever member 20 is placed on the wedge plate 30 and temporarily fixed to the receiving arm 11 by bolts or the like. At this time, if the lever member 20 does not seem to be substantially horizontal with respect to the floor surface of the vehicle, the wedge plate 30 is adjusted to move in and out to horizontally adjust the lever member 20. As shown in FIG. 2, the wedge plate 30 is literally wedge-shaped, so that the above adjustment can be easily performed. When the position adjustment of the lever member 20 is completed, the bolts and the like that have been temporarily fixed are fully tightened, and the cantilever support device 100 completes the support and fixing of the vehicle seat 200 to the vehicle wall.

In the fixing work described above, the fixing of the support body 10 to the wall side and the fixing of the lever member 20 to the vehicle seat 200 side are performed separately, and finally the lever member 2 is attached.

In the following embodiments, in order to secure the support body 10 to the vehicle more securely, the support leg 40 fixed to the floor is fixed to the tip of the receiving arm 11. However, since the fixing of the support leg 40 to the floor surface and the connection to the support main body 10 are simple, even when the support leg 40 is used, the cantilever support device 100 of the vehicle seat 200 is used. The supporting and fixing work is easy.

According to the cantilever support device 100 as described above, the load from the vehicle seat 200 side is mainly applied from the lever member 20 to the receiving arm 11 on the cantilever support device 100 side, and this load causes the cantilever support device 100. The rotational force centering on the wedge plate 30 that constitutes 100 is the lever member 20.
Will be working. However, this rotational force is completely canceled by the stopper portion 12 forming the support body 10, so that the vehicle seat 200 is stably supported and fixed to the wall. It should be noted that the force applied when the vehicle swings up and down is sufficiently prevented by fitting the support body 10 to the insertion portion 13 and fixing the support body 10 itself to the wall, which means acceleration of the vehicle. The same applies to the force in the front-rear direction of the vehicle seat 200 caused by deceleration.
