PROBLEM TO BE SOLVED: To provide a slide-type constant velocity universal joint of low costs, easy in a mounting work and capable of stably generating coming-off prevention force.SOLUTION: A coming-off prevention structure includes a stopper piece fitted between a rolling face of a torque transmission member of an outer joint member and the torque transmission member in a sliding state of an internal component to an opening portion side of an outer joint member. A taper face portion inclined from the joint opening side toward the joint depth side is disposed at the joint depth side of the stopper piece. A minimum thickness of the taper face portion of the stopper piece is determined to be equal to or less than a clearance formed between the rolling face and the torque transmission member, and a maximum thickness is determined to be equal to or more than the clearance. An inclination angle of the taper face portion is determined according to a slide friction coefficient between the stopper piece and the rolling face within a range free from slipping between the stopper piece and the rolling face.SELECTED DRAWING: Figure 1 |
