用オートテンシヨナ。[Claims for Utility Model Registration] A rocking plate is swingably mounted on a fixed base by a pivot, an idler pulley is rotatably mounted on the swinging plate via a boss, and approximately at the center of the bottom of the boss. A pin penetrating through the pin is erected on the fixed base, friction plates are provided on both sides of the bottom of the boss, and the friction plate on the inner surface of the boss is pressed against the bottom of the boss by the elasticity of a spring fitted to the pin. The autotensioner for a timing belt is configured such that appropriate friction is generated between the boss and the fixed base, and the inner diameter of the boss is arranged at a pin through hole location of the boss along the direction of swinging of the swinging plate. An autotensioner for a timing belt characterized by having a long groove with a length equal to the overall length.
