Claims

[Scope of utility model registration request]

A screw shaft with one end screwed into a screw hole provided in a fixed wall, an eccentric shaft integrally formed with the other end of the screw shaft and having an axis eccentric with respect to the axis of the screw shaft, and the eccentric shaft. It consists of a tensioner bearing and a ring-shaped fixing member that are sequentially attached to the shaft, and an eccentric groove is formed on the outer circumferential surface of the end of the inner ring of the bearing on the side opposite to the fixed wall, and on the inner circumferential surface of the inner ring side of the ring-shaped fixing member. A timing belt tensioner characterized in that the bearing is supported by a fixed wall by fitting between both eccentric grooves, and a belt is guided directly or indirectly to an outer ring of the bearing.
