The wheelchair wheel 15a is placed on the wheelchair holding portion 24 to hold the wheelchair 15, and the movable arm 23 provided with the wheelchair holding portion 24 is supported by the fixed arm 22 so as to be able to advance and retreat. The apparatus 20 can be downsized and a sufficient operating range can be secured.
The wheelchair holding part 24 can be lowered by moving the movable arm 23 having the wheelchair holding part 24 to the distal end side of the fixed arm 22 and extending, so that the wheelchair can be held only by driving the movable arm 23 forward and backward by the advance / retreat drive part 25. The part 24 can be easily moved up and down, and the structure is easily simplified.

  Since the movable arm 23 and the wheelchair holder 24 are moved up and down by the drive motor 44, the user's labor can be reduced, and the wheelchair can be accommodated and taken out quickly and safely. In that case, since it operates on the same track, the user does not need to move the wheelchair to correct the track, and the wheelchair 15 and the vehicle 10 do not interfere with each other and be damaged.

  The embodiment of the present invention is not limited to the above-described matters, and may be modified as follows, for example. In the above description, the wheelchair accommodation device is mounted in the vicinity of the rear opening of the floor 12 of the luggage compartment 11 provided at the rear of the vehicle, but may be mounted on the floor of the vehicle compartment, for example.

  In the above, the outer periphery of the large wheel and the outer periphery of the caster are mounted on the large wheel mounting portion 24a and the caster mounting portion 24b of the wheelchair holding unit 24. For example, as shown in FIG. Thus, the large wheels and the frames near the casters, bearings, and the like may be supported by the large wheel mounting portion 24a and the caster fixing portion 24c of the wheelchair holding portion 24.
