According to this configuration, the handle member 6 of the handle 5 is close to the floor surface, preferably from a height position (lower end position) where the foot support (footrest) of the wheelchair hits, a height position where an adult can easily stand and operate the handle ( Up to the upper end position), the door can be opened by pressing any part except the lower end 66 fixed by the fixing member 7 within this height range. Further, since the handle 5 is a push lever type, it can be pushed by a part of the body or pushed by a wheelchair to open the door. Therefore, it can be opened easily not only by healthy people but also by short children and wheelchair users, especially for wheelchair users who are handicapped, they do anything to open the door. Without moving the wheelchair forward, the upper portion of the lower end 66 of the handle member 6 can be pushed and opened by the foot support of the wheelchair, which is very effective.

FIG. 4 is a front view (a), a side view (b) and an enlarged side view (c) of a main part according to still another embodiment (Example 3) of the present invention. Therefore, the same or corresponding members / elements are denoted by the same reference numerals, and descriptions thereof are omitted. The difference from the first embodiment is the shape and configuration of the handle 5. In the first embodiment, the fixing member 7 is provided at the upper end of the handle member 6, and the handle member is fixed to the door-end side panel 2 via the fixing member 7. In this embodiment, the fixing member 7 is provided at the approximate center in the length direction of the handle member 6 and is connected to the door via the fixing member 7.
