イド板の離脱を防止している。この種の止め輪は小さい
ものは外径数mm程であるため、工具を用いて手作業で装
着する必要がある。A rotary shaft or slide shaft of a cassette deck or the like has a U-shaped or E-shaped retaining ring attached to the shaft end to prevent the rotary plate or the slide plate from coming off. Since this type of snap ring has a small outer diameter of about several mm, it must be manually attached using a tool.
第4図は従来の止め輪装着工具の一例で、11はチャッ
ク部、12は手で握る把持部である。チャック部11は中央
にスリット13を有し、止め輪20を弾性的に挟持する。FIG. 4 shows an example of a conventional snap ring mounting tool, in which 11 is a chuck portion and 12 is a grip portion to be gripped by hand. The chuck portion 11 has a slit 13 at the center and elastically clamps the retaining ring 20.
第5図は止め輪20を装着する軸の一例として、シャー
シ41に植設されスライド板42の長穴43を貫通した軸30を
示している。本例のスライド板42は2本の軸30A,30Bに
規制されて長穴43の方向にだけスライドする。FIG. 5 shows, as an example of a shaft on which the retaining ring 20 is mounted, a shaft 30 which is planted in the chassis 41 and penetrates the elongated hole 43 of the slide plate 42. The slide plate 42 of this example is restricted by the two shafts 30A and 30B and slides only in the direction of the elongated hole 43.
軸30の端部には第6図に示すように円周方向の溝31が

の状態でチャック部11を引くと止め輪20だけが軸31側に
残って装着される。A circumferential groove 31 is formed at the end of the shaft 30 as shown in FIG. 6, and the retaining ring 20 is mounted therein. That is, when the retaining ring 20 is pressed against the groove 31 while being held by the chuck portion 11, the opening of the retaining ring 20 opens and fits around the groove 31, and when the chuck portion 11 is pulled in that state, only the retaining ring 20 is pulled. Is left and installed on the shaft 31 side.
しかしながら、第6図(a)のようにチャック部11を

うに装着されれば理想的であるとき、軸30Bの止め輪20
のように90°回転して装着されるとスライド板42の離脱
防止機能が低下する欠点がある。However, when the chuck portion 11 is pressed while being tilted in a vertical plane as shown in FIG. 6 (a), the retaining ring 20 is also tilted and the tilting failure occurs. If the chuck portion 11 is displaced in the height direction as shown in (b) or laterally as shown in (c), the retaining ring 20 cannot be mounted on the shaft 30. Further, as in (d), the chuck part
When 11 rotates in the horizontal plane, the retaining ring 20 is also mounted in that direction. Therefore, when it is ideal to mount the retaining ring 20 like the retaining ring 20 of the shaft 30A in FIG. Ring 20
As described above, there is a drawback in that the detachment prevention function of the slide plate 42 is deteriorated when it is mounted by rotating 90 °.
本考案はかかる欠点を改善し、止め輪の装着作業を確
実、容易にすることを目的とする。It is an object of the present invention to remedy such drawbacks and to make the work of attaching a retaining ring reliable and easy.
本考案の止め輪装着工具は第1図〜第3図の構成を有

ク部、14はチャック部11より前方へ突出した高さ設定部
である。この高さ設定部14はチャック部11で挟持された
止め輪20の上面から軸30の頭部32の厚みtより僅かに高
い位置に水平に突出している。The retaining ring mounting tool of the present invention has the structure shown in FIGS. In FIG. 1, 10 is a snap ring mounting tool, 11 is its chuck portion, and 14 is a height setting portion projecting forward from the chuck portion 11. The height setting portion 14 horizontally projects from the upper surface of the retaining ring 20 held by the chuck portion 11 to a position slightly higher than the thickness t of the head 32 of the shaft 30.
第2図で15はガイド溝で、止め輪装着工具の高さ設定
部14の下面中央に形成される。また第3図で17は回転阻
止部で、高さ設定部14の先端から下方に突出する。In FIG. 2, reference numeral 15 is a guide groove, which is formed at the center of the lower surface of the height setting portion 14 of the snap ring mounting tool. Further, in FIG. 3, reference numeral 17 denotes a rotation blocking portion, which projects downward from the tip of the height setting portion 14.
本考案の止め輪装着工具10は第1図のように高さ設定
部14を軸30の頭部32に当てるように使用し、この状態で
全体を水平にスライドさせることにより、チャック部11
に挟持された止め輪20を軸30の溝31に嵌着する。As shown in FIG. 1, the retaining ring mounting tool 10 of the present invention is used so that the height setting portion 14 is brought into contact with the head portion 32 of the shaft 30. In this state, the chuck portion 11 is slid horizontally.
The retaining ring 20 sandwiched between is fitted into the groove 31 of the shaft 30.
高さ設定部14を頭部32に当てると止め輪20は溝31に嵌

その効果を一層顕著にすることができる。When the height setting portion 14 is brought into contact with the head 32, the retaining ring 20 is held at a height at which it can fit in the groove 31, so that the retaining ring 20 cannot be mounted due to a height failure as shown in FIG. 6 (b). I don't care. Further, although the defects shown in (a), (c), and (d) of FIG. 3 can be almost prevented by sliding the height setting portion 14 horizontally, the guide groove 15 of FIG. 2 and the rotation blocking portion 17 of FIG. By forming it, the effect can be made more remarkable.

の不良を確実に防止できる。FIG. 2 is a block diagram of the first embodiment of the present invention, (a) is a front view and (b) is a plan view. Retaining ring installation tool 10 of this example
A guide groove 15 into which the head 32 of the shaft 30 is inserted is formed in the center of the lower surface of the height setting portion 14 so as to prevent the lateral deviation defect in FIG. 6 (c). The opening 16 of the guide groove 15 may be inclined so that the head 32 can be easily inserted even if there is some positional deviation. According to this example, FIG. 6 (b) (c)
It is possible to reliably prevent the defects.

止でき、更に第2図のガイド溝15と併用すれば横ずれも
防止できるので、止め輪20の装着が最も確実になる。FIG. 3 is a block diagram of a second embodiment of the present invention. In this example, a rotation blocking portion 17 protruding downward from the tip of the height setting portion 14 is provided, and the tip thereof is inserted into the elongated hole 43 of the slide plate 42 so that the horizontal plane as shown in FIG. It is designed to prevent rotation. That is, the tool 10 of this example makes the height setting part 14 contact the head part 32 of the shaft 30 while the rotation prevention part
Since the whole slides with the tip of 17 inserted in the long hole 43, the sliding direction is only the direction of the long hole 43,
The retaining ring 20 is mounted in an ideal rotational position similar to that for the shaft 30A in FIG. 5 (b). Incidentally, if the tip of the rotation blocking portion 17 is brought into contact with the chassis 41, the inclination shown in FIG. 6 (a) can be prevented, and if it is used together with the guide groove 15 shown in FIG. The attachment is most reliable.
以上述べたように本考案によれば、微小な止め輪を軸
に装着する作業を容易に且つ確実に行うことができる利
点がある。As described above, according to the present invention, there is an advantage that the work of mounting the minute retaining ring on the shaft can be easily and surely performed.
