ABSTRACT:
An auto-tensioner has an arrangement wherein a pivoting member rotatably supports a pulley in contacted relation with a belt and is pivotally biased by a spring for pressing the pulley against the belt. A bracket is press fitted around the outer periphery of the pivoting member and one end of the spring is locked to the bracket. A first fit portion disposed at the pivoting member and a second fit portion disposed at the bracket are fitted with each other for restriction of a relative rotation between the pivoting member and the bracket.
