Abstract: A wheelchair is provided which includes a body, and driving wheels arranged on the both sides of the body. The wheels include a rim portion, a hub portion, an hand rim, and fastening members. A tire is attached to the outer peripheral part of the rim portion. The hub portion is arranged at the center of the rim portion and coupled to the rim portion by connecting members. The hand rim is arranged along the rim portion on the exterior side of the rim portion. The fastening members fasten the hand rim to the rim portion. An insertion prohibition spacing is formed between the rim portion and the hand rim. The spacing has a distance capable of prohibiting insertion of user's thumb into this spacing.

Abstract: A wheelchair is provided which includes link rods that intersect each other in an X shape, and are pivotably coupled to each other by a pivot shaft. The link rods include a rod central part, and rod upper and lower parts. The rod central parts hold the pivot shaft. The rod upper and lower parts and slant from first and second inclined parts on the both ends of the rod central part in opposite directions with respect to the rod central part. When the X-link portion is folded, the rod central parts overlap each other and are aligned in one straight line in the vertical orientation, and frame accommodation space portions which can accommodate the middle frame portions are provided on the both sides of the rod central parts.

Abstract: A wheelchair is provided includes driving wheels, a pair of side frames, and an accommodation pocket. The frames rotatably support the driving wheels coupled to the exterior sides of the side frames. Each of side frames includes an elbow rest frame portion, a vertical frame portion, and a lower frame portion. The elbow rest frame portion has an elbow rest. The vertical frame portion is coupled to the rear end part of the elbow rest frame portion. The lower frame portion is arranged under the elbow rest frame portion. The vertical frame portion is coupled to the rear end part of the lower frame portion. The accommodation pocket is arranged above the front part of the driving wheel as viewed in side view, and is at least partially positioned on the exterior side relative to the elbow rest frame portion as viewed in front view.

Abstract: A wheelchair is provided which includes driving wheels, side frame, footrest arms, and footrest plates. The driving wheels are rotatably coupled to the exterior sides of the side frames. The footrest arms are movable between arm unfolded and folded positions. Each of the footrest arms is pivotably coupled to an arm pivot shaft. The arm pivot shaft is positioned on the exterior side of each of the side frames in front of each of the driving wheels. The footrest plates can support user's feet. Each of the footrest plates is coupled to the fore end of each of the footrest arms. The distance between the fore ends of the footrest arms in the arm unfolded position is smaller than the distance in the arm folded position.
