れている。FIG. 3 is an external view of a wheelchair equipped with a wheel having a conventional rim. A wheelchair main body 1 in which a plurality of frames are combined left and right and front and rear, has a pair of left and right running wheels 2 arranged at the rear part thereof and a front wheel. A pair of left and right auxiliary wheels 3 arranged at four parts are supported at four points, and a cloth or the like is stretched between the frames. The leg rest 6 is fixed to the lower side, and the elbow pad 7 is fixed to both right and left sides of the seat surface 4. Then, by gripping the handling 9 that is provided around the outside of the running wheel 2 with both hands of the user who extend downward from the upper side of the elbow pad 7, a rotational force is applied to both or one of the handling 9,
It is possible to move by itself by going straight or turning. The handling is usually attached to the rim of the traveling wheel with a mounting member such as a bolt. For example, the actual exploitation 4
9-25149 or Japanese Utility Model Laid-Open No. 52-53563. That is, as shown in FIG. 5, the former is attached to the rim 8 of the traveling wheel by a bolt 11 so as to project laterally in the axial direction of the traveling wheel to the outside.
The handling 9 is attached concentrically with the running wheels by laterally projecting outward from the running wheels with ~ 5 mounting brackets 12. In the latter, as shown in FIG. 6, a handling 9 is concentrically attached to the outside of the traveling wheel 2 via a bolt 11 provided laterally at the base end of a clamp 13 held by the traveling wheel 2. .

【００２２】従って、本発明の組立て工程数は従来の工
程数に比し、１３工程−６工程＝７工程の削減になる。
さらに４〜６か所の挟持金具やボルト等の取付金具が不
要になり部品数が半減する。Therefore, the number of assembling steps of the present invention is reduced by 13 steps-6 steps = 7 steps as compared with the conventional number of steps.
Furthermore, the number of parts is reduced by half because there is no need for clamping metal fittings such as bolts or bolts at 4 to 6 places.

く、また、しっかりと強く握ることができる。As described above, the rim with handling of the present invention is formed by integrally molding the rim of the wheelchair traveling wheel, the handling for driving the traveling wheel and the rib connecting them, and the rib is a continuous ring. Since the number of manufacturing steps of the rim with handling of the present invention is approximately half of the number of conventional manufacturing steps, and the number of parts is halved compared to the conventional one, the working time and cost are greatly reduced. it can. Furthermore, since the rib is a continuous annular surface and there is no gap between the rim and the handling, wheelchair users do not thrust their fingers into the gap when traveling, so the rotation due to the inertial force of the running wheels injures the fingers. You will not be affected and will not lose your handling, and you will be able to hold firmly and firmly.
