Abstract
An automatic adjustment apparatus comprises a pulley having a spindle hole, an one-way bearing disposed in the spindle hole, a two-way bearing disposed in the spindle hole and located at a side of the one-way bearing, a sleeve and at least one constraint component. The sleeve is disposed in the one-way bearing and the two-way bearing, and a constraint portion is concaved at a side of the sleeve. The constraint component is mounted on the constraint portion for constraining the displacement of the pulley moving at the axial direction of the sleeve. Therefore, the pulley can glide at the sleeve so as to prevent inclination of the installing position of a belt at the pulley which results in rapid abrasion in belt and bad driving safety.
