三つ折れ中留のバンド長さ調整構造の従来技術としては、実開昭５２−１１０ ８７３号公報に開示されている。この構造は、図６の断面図に示す様に表カバー １と中板（図示せず）の間に補助金具２と摺動片５を配置し、補助金具２と表カ バー１とを周知のバネ棒６によって連結し、同じく摺動片５と中板とをピン（図 示せず）にて連結している。補助金具２と摺動片５とは、補助金具２の底面に形 成した複数個の止め穴７に摺動片５に固定されたコ形バネ４、係止爪３を係合す ることにより連結している。バンドの長さを調整するには、係止爪３を複数の止 め穴７に順次移動させることで行ない、補助金具２のストッパー８に当たるまで 移動することができる。 As a conventional technology of the band length adjustment structure of the three-fold clasp, there is It is disclosed in Japanese Patent No. 873. This structure has a front cover as shown in the cross-sectional view of Figure 6. 1 and a middle plate (not shown), place the auxiliary metal fitting 2 and the sliding piece 5, and connect the auxiliary metal fitting 2 and the front cover. The bar 1 is connected with a well-known spring rod 6, and the sliding piece 5 and the middle plate are connected with a pin (Fig. (not shown). The auxiliary metal fitting 2 and the sliding piece 5 are shaped on the bottom of the auxiliary metal fitting 2. The U-shaped spring 4 fixed to the sliding piece 5 and the locking pawl 3 are engaged with the plurality of locking holes 7 formed. It is connected by this. To adjust the length of the band, move the locking claw 3 This is done by moving it sequentially through the holes 7 until it hits the stopper 8 of the auxiliary fitting 2. Can be moved.

しかしながら、この構造は補助金具２と摺動片５は、係止爪３と止め穴７によ る弾性係合であるため、バンドに僅かな力が作用しても係合が外れてしまう欠点 があった。したがって、バンドが緩むことが多く装着性に劣る。本考案は、上記 問題点を解決し、バンド長さ調整を簡単に行ない、且つ確実にロック出来、その 上、簡単構造で外観品質の優れた三ツ折れ中留の長さ調整構造を提供することを 目的とする。 However, in this structure, the auxiliary fitting 2 and the sliding piece 5 are connected to the locking claw 3 and the locking hole 7. Since it is an elastic engagement, the band may become disengaged even if a slight force is applied to it. was there. Therefore, the band often becomes loose, resulting in poor wearability. This invention is based on the above Solve the problem, easily adjust the band length, and lock securely. Above, we provide a simple structure with a three-fold clasp length adjustment structure that has excellent appearance quality. purpose.
