摘要： A method of manufacturing a spline telescopic shaft, includes a sliding step of sliding in an axial direction an inner shaft manufacturing intermediate member and an outer shaft manufacturing intermediate member, in one of which a resin coating is disposed on splines. In the sliding step, a sliding load of the inner shaft manufacturing intermediate member and the outer shaft manufacturing intermediate member is detected, and sliding is ended at a timing when the detected sliding load reaches a threshold load which is determined based on an initial sliding load detected at a start of the sliding.

摘要： A universal joint includes a bearing including a bearing cup fitted in a bearing hole of a yoke and rolling elements arranged between the bearing cup and a shaft portion of a cross shaft. A method for manufacturing the universal joint includes: simulating a shrunken state in which a sample bearing cup selected from bearing cups in a same lot is fitted in the bearing hole such that only an outside diameter is restrained, by press-fitting the sample bearing cup into a reference hole of a reference jig; measuring a diameter of an inscribed circle inscribed to the rolling elements in the shrunken state; setting an outside diameter of the shaft portion to a required outside diameter according to the diameter of the inscribed circle; and inserting the bearing cup with the rolling elements between the shaft portion having the required outside diameter and the bearing hole.

摘要： 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.
