Claims

[Scope of utility model registration request]

A sleeve fixed to the engine body via a support shaft and having outer teeth formed on the outer periphery; and a sleeve fitted to the outer periphery of the sleeve so as to be slidable in the axial direction via inner teeth that mesh with the outer teeth. a slide member, which is rotatably supported on the outer periphery of the sleeve by meshing the inner teeth formed on the inner circumferential surface with the outer teeth formed on the outer circumferential surface of the slide member, and whose center is away from the center of the sleeve; An eccentric annular body, a tensioner pulley that is rotatably provided on the outer periphery of the body and comes into contact with the transmission belt, and a sliding member in which at least one of the internal and external teeth is a helical tooth is moved in the axial direction. 1. A power transmission belt tension adjustment device comprising: a spring member that presses in either direction; and a temperature sensing mechanism that moves a slide member in the axial direction against the spring force of the spring member.
