The wheelchair fixing device 18 is mainly composed of a pair of left and right hook belts 20 for fixing the front leg portions 19 of the wheelchair 2 and a tightening belt 22 for fixing the rear leg portions 21, both of which are reinforcement frames. It is attached to 23. The reinforcing frame 23 is made of steel and is sandwiched between the vehicle floor 24 and the second floor 25 forming the "floor" of the vehicle on which the wheelchair 2 is placed. That is, the reinforcement frame 23 is on the second floor 25.
It is buried under the floor.

The hook belt 20 is a hook 26 made of steel as a "hook" that can be hooked on the front leg 19 of the wheelchair 2, and this hook 26.
Is composed of a fixed-length belt 27 attached to the tip and a retractor 28. Since the retractor 28 is attached to the reinforcing frame 23 via the bracket 29, the retractor 28 is buried under the second floor 25. Further, since the fixed length belt 27 is wound and stored in the retractor 28 by a spring (not shown), it is stored under the floor when not in use. The hook 26 is also stored and placed in the storage recess 31 provided in the cover plate 30 in a flat state at the same time when the standard length belt 27 is wound and stored under the floor, so that the second floor 25 is eventually used. There is nothing protruding above. Further, the standard length belt 27 is drawn out by the same fixed dimension on both the right and left sides when used, so that the right and left sides can be balanced by only pulling out the standard length belt 27 and fixing the wheelchair 2. It is a thing.
In addition, 32 is an edge protector, and the standard length belt 27 is wound up.
This is for preventing the edge of the cover plate 30 from being damaged when stored. (Refer to FIG. 3) The tightening belt 22 is a belt body 34 having carabiner 33 as a "hook" to be hooked on the rear leg portion 21 of the wheelchair 2 attached at both ends thereof, and an intermediate portion of the belt body 34 serves as a guide. It is composed of a pair of left and right guide belt anchors 35 that can be inserted through the holes. The belt body 34 is a state in which the short belt 36 and the long belt 37 are connected to each other via the buckle 38 with a lock, and the lock lever 39 is raised to unlock, and the free end portion 40 of the long belt 37 is fixed. By pulling, the length size of the entire belt body 34 can be adjusted. Also,
Since both belt anchors 35 are attached to the reinforcing frame 23 that is buried under the floor of the second floor 25 through the stepped portion 42 of the bracket 41, this is also buried under the floor of the second floor 25. .
