こと、等の問題がある。However, the above-mentioned conventional mounting apparatus is still unsatisfactory from the following points. That is, in this mounting device, the retaining ring 1 at the distal end is placed on the projection end surface 72 of the base member 70 on the fixed side, and the shaft 7 is lowered from above through the pusher 78. For this reason, as a device structure, first, a lowering mechanism of the shaft 7 is required, and if the shaft 7 is lowered while maintaining parallelism, the mechanism becomes complicated mechanically. Further, in this structure, since the stopper plate 74 for receiving the retaining ring 1 at the tip from one end face side is indispensable, for example, the shaft already mounts components such as gears as shown in FIG. 1 of the present invention. In that case, the shaft-mounted part is disturbed and cannot be mounted and is restricted by the applicable shaft,
In the case where there are two grooves for mounting the retaining ring close to each other as in the shaft of FIG. 4, there are problems that the retaining ring 1 cannot be mounted at the same time and the mounting efficiency is poor.

That is, the supply means of the present invention may be any as long as it presses the plurality of retaining rings against the guide pillar toward the free end side of the pillar by an urging member or the like. The holding means may be any as long as it can support the object shaft at a fixed position. The guide means can be constituted by a thin plate such as a flat plate or a spring plate. The pusher means may be any means that drives the retaining ring holder capable of receiving and retaining one retaining ring in a direction intersecting the free end of the guide support. It is excellent in versatility because it is hardly restricted by the shaft and the groove for mounting. That is, the present invention is different from the structure of FIG. 5 in that the shaft is fixed in position by the holding means, the leading end retaining ring of the supply means is retained by the retaining ring holder, and the retaining ring is provided by the pusher means. Since it is characterized in that it is moved to the retaining ring mounting position by mechanical movement, when the shaft has already mounted parts such as gears as shown in FIG. 1, the groove of the shaft is adjacent as shown in FIG. It is also possible to easily cope with a case where a pair is provided. In addition, when the retaining ring is continuously mounted on a large number of shafts, the tact time is reduced, and an efficient mounting operation is realized. That is, in the operation of the apparatus, the replacement of the shaft can be simplified, and the next retaining ring of the guide support may be moved based on the shaft replacement time.
