Conventionally, the structure shown in FIG. 5 is common as a structure for fixing a bearing to a shaft member. That is, the bearing 1 is fitted onto the shaft member 2, one end of which is brought into contact with the positioning shoulder 2a of the shaft member 2, and an annular groove 2b is formed in advance at the tip of the shaft member 2 protruding from the other end of the bearing 1.
Fit the retaining ring 3 to the retaining ring 3, and use the retaining ring 3 to
The bearing 1 is fixed through the shaft and prevented from moving in the axial direction.

In the above fixed structure, the tip of the shaft member 2 is connected to the bearing 1.
Since it is necessary to protrude from the end face of the shaft member 2,
The overall length of the device increases accordingly, making the entire device larger.
In addition, since the number of parts increases, the cost also increases, making it uneconomical.

するという問題がある。 Therefore, in order to eliminate the above-mentioned drawbacks, as shown in FIG.
A retaining ring 3 having a circular cross section is fitted to b, and the outer diameter part of this retaining ring 3 is attached to the inner diameter surface of the inner ring 5 of the bearing 1 on the shaft member 2.
An annular groove 5a provided opposite to the annular groove 2b of
Japanese Utility Model Publication No. 12425/1983 discloses a device that protrudes inward to fix the bearing 1 and prevent its movement in the axial direction. However, since the retaining ring 3 has a circular cross section, if the amount of protrusion of the retaining ring 3 into the groove 5a is not appropriate, reliability in preventing the retaining ring from coming off will be lacking. Therefore, it is necessary to strictly control the dimensions of the annular groove 5a of the inner ring 5, which is time-consuming and disadvantageous in terms of cost. In addition, the annular groove 5a of the inner ring 5 has to be made deeper in order to ensure that the inner ring 5 does not come off, which causes a problem in that the strength of the inner ring 5 and, by extension, the strength of the bearing 1 is reduced.
この考案は上述の問題点を解消しうる円筒部材
の固定構造を提供せんとするものであり、そのた
めには軸受等の被固定部材に設ける溝を浅くして
も確実な抜け止めが図れるようにすることが主要
な課題となる。 This idea aims to provide a fixing structure for a cylindrical member that can solve the above-mentioned problems, and for this purpose, it is possible to securely prevent it from coming off even if the groove provided in the fixed member such as a bearing is made shallow. The main challenge is to
この考案は、止め輪を円筒部とその一端から弧

In this invention, the retaining ring is formed into an L-shaped cross section consisting of a cylindrical portion and a flange extending radially from one end of the retaining ring through an arcuate outer surface, and the cylindrical portion is fitted into an annular groove of a member to be fixed. The open end is brought into contact with the shoulder of the annular groove, and the flange is brought into contact with the shoulder of the annular groove of the counterpart member.
止め輪は、一方では円筒部が被固定部材の環状

も被固定部材の環状溝を浅くしても抜け止めの信
頼性が低下する心配はない。
On the one hand, the retaining ring has a cylindrical portion that fits into an annular groove of the member to be fixed, and an open end that abuts a shoulder of the annular groove;
On the other hand, the flange abuts against the shoulder of the annular groove of the other member, thereby reliably engaging both members. Therefore, even if the annular groove of the fixed member is made shallower than in the case of a retaining ring having a circular cross section, there is no fear that the reliability of retaining the retaining member will deteriorate.

This device forms a retaining ring with an L-shaped cross section consisting of a cylindrical part and a flange part, fits the cylindrical part into an annular groove of a fixed member, and makes the open end abut against the shoulder part of the annular groove. At the same time, since the flange is brought into contact with the shoulder of the annular groove of the other member, when an external force is applied in the direction in which the member to be fixed is pulled out, the shoulder of the annular groove of the member to be fixed and the annular groove of the other member are The retaining ring tightens between the shoulder part of the retaining ring and the cylindrical part bulges into a shape that prevents it from coming off the groove, thereby preventing movement of the fixed member. Since the securely fixed state is maintained in this manner, the groove of the fixed member into which the cylindrical portion fits can be made shallower, thereby suppressing a decrease in the strength of the cylindrical member. In addition, since it is possible to reliably prevent the groove from coming off without strictly controlling its dimensions, machining is easy and it is advantageous in terms of cost.
