せて脱落を防止している。A conventional example of a pad pin locking clip, which the present application intends to improve, is shown in FIGS. 4 to 6. In the figure, 1 is a clip made of spring steel wire, 2 is a caliper, 3 is a pair of friction pads inserted so as to face the central opening 4 of the caliper, and 5'is to pin supporting walls 6 and 7 of the caliper. Central opening 4 through
Pad pins provided on the disk entry side and the disk exit side of the disk. By passing these pins 5 and 5'on the back plate, the pair of pads 3 and 3 are supported slidably in the disk axial direction. Further, the pad pins 5 and 5 ′ are provided with a hole at a front end penetrating the wall 7 and perpendicular to the axis, and the clip 1 is inserted in the hole.
The both ends of the clip 1 are prevented from coming off by passing them in opposite directions, and the clip 1 is detached by locking the central hook portion 1a to the fixing hole 8 in the disc axial direction provided in the support wall 7 as shown in FIG. Is being prevented.

シリンダ９の外側から定着孔８に挿入するため、シリン
ダ外面に冷却フィンが設けられるアルミキャリパ等の場
合、クリップとフィンが干渉し、装着が難しい。In a conventional clip of this type, the hook portion 1a is inserted into the fixing hole 8 from the outside of the cylinder 9 of the caliper. Therefore, in the case of an aluminum caliper in which a cooling fin is provided on the outer surface of the cylinder, the clip and the fin interfere and the mounting is difficult. difficult.

If you do not make it large to some extent, the amount of push down required to push down and remove the clip cannot be secured, and the replaceability of the clip will deteriorate.
さらに、フック部１ａが定着孔８を貫通するため、キャ
リパのアルミ化等で孔８の長さｌ１が長くなるとフック
部の長さｌ２も長くなり、脱着がより困難になる。Further, since the hook portion 1a penetrates through the fixing hole 8, if the length l 1 of the hole 8 becomes longer due to the use of a caliper made of aluminum or the like, the length l 2 of the hook portion also becomes longer, which makes attachment and detachment more difficult.
この考案は、これ等の不都合を解消することを目的とし
ている。The present invention aims to eliminate these inconveniences.
この考案は、上記の問題点を無くすため、第１図乃至第

状となす。In order to eliminate the above-mentioned problems, the present invention, as shown in FIGS. 1 to 3, has a hook portion 1a which is locked to the fixing hole 8 of the pin support wall 7 from the outside of the pin support wall 7. The shape is such that it extends over the inside and is inserted into the clip fixing hole 8 from the side opposite to the wall surface that receives the clip end (the side of the central opening 4 of the caliper).

Figure), in order to eliminate the natural escape from the hole 8, keep the elongated than flexibility of the movement of the extraction direction of the pad pins 5,5 '(L 3 of FIG. 1).
以上の構成としたこの考案のクリップは、フック部１ａ

ンダ９外周に図に示す如き冷却フィン１０が存在して
も、そのフィンに干渉することなく容易に装着できる。The clip of the present invention having the above-described structure is provided with the hook portion 1a.
Since it is in a position to straddle the pin support wall 7, even if the cooling fin 10 as shown in the drawing is present on the outer periphery of the cylinder 9 of the caliper, it can be easily mounted without interfering with the fin.
また、フック部１ａ先端の定着孔８への挿入は支持壁７

のレイアウト面での自由度も高まる。Further, the insertion of the tip of the hook portion 1a into the fixing hole 8 is performed by the support wall 7
Since there is no need to secure a space for pushing down the clip between the hole 8 and the outer circumference of the cylinder 9, since it is performed from the upper part (outer diameter side of the disc), H in FIG. The size of the clip can be reduced, and the degree of freedom in the layout of the clip itself is increased.

も脱着性の悪化がない。Further, the length L 2 of the bent back portion at the tip of the hook portion 1a to be inserted into the fixing hole 8 may be a dimension that prevents spontaneous escape regardless of the length L 1 of the hole 8, and L 1 is large. Even if it becomes, the detachability does not deteriorate.

キの組立や保守の簡易化に役立つと云う効果がある。As described above, in the clip of the present invention, since the central hook portion is inserted into the fixing hole in the opposite direction to the conventional one, straddling the pin support wall, the clip is excellent in layout property and detachability.
This is effective in simplifying the assembly and maintenance of the disc brake that supports the friction pad with the pad pins of the book.

ッドピンの係止クリップ。1. A disc brake in which a pair of friction pads sandwiching a disc from both sides are supported by two pad pins so as to be slidable in the disc axial direction. One end and the other end of the disc brake are respectively passed through the pin holes of the pad pins. It is a wire spring clip that passes through in the direction perpendicular to the pin axis and locks the center hook part with the clip fixing hole in the disk axis direction provided on the pin support wall of the caliper to prevent the two pad pins from coming off from the caliper. And the hook portion is shaped to be inserted into the clip fixing hole from the side (the central opening side of the caliper) opposite to the wall surface that straddles the pin support wall and receives the clip end.
