And a string or band extending from the winding means to the free end of the boom and hanging from the free end.

[0006] It is preferable that the angle of the boom with respect to the post in the vertical direction is adjustable, and that the post is tiltable and can be disposed on the floor.

[0007]

[Operation and Effect] To load the wheelchair into the cabin, rotate the boom toward the wheelchair, bring the tip of the string or band to the wheelchair, and hook the hook normally provided at the tip of the string or band to the frame of the wheelchair. Then, the string or the band is wound up by the winding means, and the wheelchair is placed on the floor of the passenger compartment.
Conversely, to lower the wheelchair from the passenger compartment, the string or band is slightly rolled up by the hoisting means, the wheelchair is lifted, the boom is turned and the hoisting means is rewound, and the wheelchair is guided on the road.

[0008] Since the boom is attached to the post so as to be pivotable in the horizontal direction, both can be arranged at a position where the post and the boom do not obstruct the driver's rear view. In addition, the wheelchair can be loaded and unloaded in a wide range by turning the boom. Since loading and unloading of a wheelchair can be basically performed by turning the boom and winding or rewinding by the hoisting means,
The operation is simple.

If the vertical angle of the boom with respect to the post is adjustable, the free end of the boom can be as close as possible to the wheelchair, so that the free end of the boom is too far from the wheelchair.
