Abstract
A constant velocity universal joint includes an outer joint member and a joint internal component received in the outer joint member. A shaft is fitted into an inner joint member. The outer joint member has a cup bottom formed on a side opposite to a shaft-fitting side. The cup bottom is configured to regulate movement of the joint internal component toward the side opposite to the shaft-fitting side in a normal state in which an impact generated in an abnormal state is not applied. The cup bottom has a cut portion which is to be cut by the impact generated in the abnormal state involving movement of the joint internal component toward the side opposite to the shaft-fitting side.
