24を固定するための止め具16とからなる。The tightening band 20 is a belt-shaped member 12 that is a belt-shaped metal plate.
And a lever 24 for reducing the diameter of the belt-shaped member 12, and a lever
It comprises a stopper 16 for fixing 24.
帯状部材12の一端側には、係止部としての係止凸部22が

部材12を輪状に形成した際に、係合凸部22の開口22aに
斜めに挿入するものである（第１図参照）。Further, the other end of the belt-shaped member 12 is overlapped to the middle portion of the lever 24, and the other end of the belt-shaped member is fixed to the middle portion of the lever 24 by spot welding. A convex portion 24a for engaging with the opening 22a of the engaging convex portion 22 is formed at the end portion of the lever 24 on the overlapping side with the belt-shaped member 12. The convex portion 24a is inserted obliquely into the opening 22a of the engaging convex portion 22 when the belt-shaped member 12 is formed in a ring shape (see FIG. 1).

なわち、止め具16を構成する起立辺16a、16aが帯状部材
12を挟むように外方に起立している。In the vicinity of the locking projection 22 on one end side of the belt-shaped member 12, a stopper 16 bent in a U-shape is formed so as to straddle the belt-shaped member 12 and open at both ends outward. It is fixed. That is, the standing edges 16a and 16a that form the stopper 16 are strip-shaped members.
Standing outward so that 12 is sandwiched.
この例の締付けバンド20の締付け動作について述べる。The tightening operation of the tightening band 20 of this example will be described.
ホース等の被締結物30をパイプ32に接続し、この被締結
物30の接続部分外周面に締付けバンド20を巻き付ける。An object to be fastened 30 such as a hose is connected to a pipe 32, and a tightening band 20 is wound around the outer peripheral surface of the connected portion of the object to be fastened 30.
そして、締付けバンド20のレバー24の凸部24aを、帯状
部材12の一端の係合凸部22の開口22aに係合する。そし

この起立片16a、16aをハンマー等で叩いて対向方向（内
側）に倒してレバー24を固定する（第４図参照）。Then, the convex portion 24a of the lever 24 of the tightening band 20 is engaged with the opening 22a of the engaging convex portion 22 at one end of the belt-shaped member 12. Then, by rotating and tilting the lever 24 with the convex portion 24a as a fulcrum, the lever member 24 leverages to reduce the diameter of the ring-shaped belt member 12, and the tip of the lever 24 is positioned between the upright pieces 16a and 16a.
The upright pieces 16a, 16a are hit with a hammer or the like and tilted in the opposite direction (inward) to fix the lever 24 (see FIG. 4).

乗り越えたりすることがない。The opening 22a of the engaging convex portion 22 is located on the side of the stopper 16 (the belt-shaped member 12
Since it is opened only in the other end side direction), it does not deform even if a force is applied to the fulcrum end of the lever 24. Further, the convex portion 24a of the lever 24, which is engaged with the opening 22a of the engaging convex portion 22, does not disengage in the circumferential direction or the width direction of the belt-shaped member 12 and does not get over the engaging convex portion 22.
一方、レバー先端の凸部24aの形状を、第３図に示すよ
うに、先端が先細になるように形成することにより、係
止部の開口22aへの係合が一層容易になる。On the other hand, by forming the shape of the convex portion 24a at the tip of the lever so that the tip is tapered as shown in FIG. 3, the engagement of the engaging portion with the opening 22a becomes easier.
