ABSTRACT:
A tripod type constant-velocity universal joint includes an outer ring having three axially-extending track grooves in its inner periphery, a tripod member mounted in the outer ring and having three trunnions extending into the track grooves, and guide blocks supported on the trunnions in the track grooves, respectively. Rolling elements are disposed in raceway grooves on opposite sides of each guide block between the guide block and the outer ring. The rolling elements are retained by retainers and a moving amount restricting mechanism restricts the moving amount of the retainers to half the moving amount of the guide blocks. Each retainer has retaining plate portions retaining the rolling elements on each side of the guide block, and a plate portion coupling together the retaining plate portions. Each restricting mechanism includes a lever pivotably supported on the plate portion and having guide grooves into which protrusions are slidably fitted.
