Problems solved by technology

However, if it is made to deform easily, the thrust may deform it when it is installed, so it cannot be installed
So since it requires a certain level of strength, the resistance increases when it is pushed in, will need to push more than necessary, so this makes the whole installation job inefficient

[0078] [The first and second embodiments (refer to Figure 1-6 )]

[0079] figure 1 and Figure 4 are the front views of one end of the first embodiment and the second embodiment, respectively, figure 2 and Figure 5 yes figure 1 and Figure 4 bottom view of image 3 and Figure 6 yes figure 1 And and Figure 4 E-E and F-F cross-sectional views, wherein a movable plug-in recess 6 with an inner periphery as a circumferential surface is formed in the end surface of the support 1, and a semicircular escape notch 7 is also formed in all of the support 1 the end. Not only the inner diameter of the inner periphery of the escape notch 7 is larger than the inner diameter of the central hole X of the buckle W, but also the inner diameter of the circumferential bottom surface of the movable plug-in recess 6 is larger than the outer diameter of the buckle W. Moreover, the protective space 5, 5a is defined between the two sides of the buckle W and the circumferential bottom su...

[0088] [eighth embodiment (refer to Figure 22-24 )]

[0089] In the innermost part of the rear part of the movable plug-in dimple 6 , a dimple 11 narrower than the groove width of the movable plug-in dimple 6 is continuously formed on the front side of the support 1 . A pair of elongated cutouts 12, 12a leading to the escape notch 7 are formed on both sides of the recess 11 on the front side of the body. Then, the area between the cutouts 12 and 12a can serve as the elastic sandwich panel 13, and the protrusions 18 (two protrusions in the figure) are integrally formed on the inner surface of the sandwich panel 13. In addition, a step formed in a boundary area between the movable insertion-type dimple 6 and the dimple 11 may be the contact portion 3 .

Abstract

A problem where a tool is deformed when a retaining ring is fitted on a shaft is solved. Plate members ( 2, 2 a) positioned at at least one side of a full back surface of a retaining ring (W) are arranged at a holder ( 1 ) provided at the head of a tool body. A contact portion ( 3 ), a portion opposite an opening portion (Y) in the outer periphery of the retaining ring (W), is provided more backward than the heads of the plate members ( 2, 2 a). Fall-off prevention means ( 4 ) from which the retaining ring (W) can be easily detached is provided at the holder ( 1 ). There are sheltering spaces ( 5, 5 a) arranged outside both side portions of the retaining ring (W) in its installed state. When the retaining ring (W) is installed to the holder ( 1 ), the retaining ring (W) does not fall off because of the fall-off prevention means ( 4 ). Further, even when the retaining ring (W) is slightly opened by being pressed by the contact portion ( 3 ) when the ring is fitted on a shaft (S), both side portions do not come into contact with the holder ( 1 ) side and therefore the holder ( 1 ) is not deformed.

Description

technical field [0001] The present invention relates to an installation tool for installing a retaining ring having an opening, such as a C- or E-ring, onto a shaft. Background technique [0002] Conventionally, there are many such installation tools (for example, refer to Patent Documents 1-6), in which the retaining portion of the buckle has an arc-shaped notch slightly larger than a semicircle so that it does not abut when it is installed on the shaft. The shaft of the buckle, wherein not only the groove for holding the buckle is formed in the notch, but also the slit is formed in the central area of ​​the notch and the groove in the vertical direction, wherein when the outer diameter area of ​​the buckle is inserted into the holding After parting so that the opening faces one end, the opening of the retaining ring is applied to the shaft and the squeeze of the installation tool slightly expands and opens the retaining ring, followed by the retaining part, thereby install...
