Abstract
A cross shaft joint includes a bearing cup, a cross shaft, and a joint yoke. The bearing cup includes a cylindrical portion in which an opening portion for receiving a shaft portion is formed in one end of the cylindrical portion in an axis direction, and a bottom portion that closes the other end of the cylindrical portion in the axis direction. The bearing cup is press-fitted into the fitting hole and supports the shaft portion through a rolling element so that the shaft portion is able to rotate. The bearing cup is fitted onto the shaft portion inside the fitting hole and holds the rolling element with the shaft portion. A diameter of an inner peripheral surface of the cylindrical portion is smaller on the opening portion side than the bottom portion side in a free state of the bearing cup before being press-fitted into the fitting hole.
