ABSTRACT:
A tensioner for an endless power transmission chain or belt comprises a transmission-engaging element for directly contacting the transmission and applying tension thereto while permitting the transmission to move past the transmission-engaging element, a sliding element mounted for longitudinal movement along a line of movement extending toward the transmission-engaging element, a spring urging the sliding element along said line of movement in a direction toward the transmission-engaging element, and a pad made of plastics material, secured to an end of the sliding element and urged into engagement with the transmission-engaging element by the spring whereby the transmission-engaging element is urged against said transmission by the pad. The pad is mounted on a plate on the end of the sliding element, and secured to the plate by resilient engagement of the plate in an interior space or pocket of the pad, or by the engagement of molded projections of the pad with holes or recesses of the plate, or by press-fitting the sliding element into a hole in a plate received in an interior space within the pad.
