摘要： There is provided a method capable of producing a wheel-supporting rolling bearing unit at low cost. In an event of producing a wheel-supporting rolling bearing unit (1), a cylindrical portion (11) formed in an axial end portion of a hub ring (2) is inserted through an inner ring (3), swing caulking is performed by pressing a die (23) against a tip end portion of the cylindrical portion (11) protruding to an axial end portion side more than the inner ring (3), and an axial end surface (3a) of the inner ring (3) is held by a caulked portion (12) formed by caulking and expanding the tip end portion of the cylindrical portion (11) radially outward. In such a way, the inner ring (3) and the hub ring (2) are fixed integrally witch each other. At this time, a swing angle of the swing caulking is set at 15 degrees or more to 30 degrees or less.

摘要： Provided are a manufacturing method and manufacturing device that allow the depth of rack teeth to be adequately maintained across the axial direction. A stepped surface (47) is provided on one surface in the axial direction of a pressure punch (46) that moves together with a teeth-forming punch (32). The teeth-forming punch (32) is displaced downward and rack teeth are formed on the upper surface of an intermediate material (23). At the same time, the surface on the end in the axial direction of the intermediate material (23) is pressed in the axial direction by a movable die (41a) due to the engagement between the stepped surface (47) and the surface on the other side in the axial direction of the movable die (41a).

摘要： Structure of a cross universal joint is achieved in which the fact that an excessive torque was applied to a universal joint due to a collision accident or mishandling can be easily determined afterwards. Protrusions 20, which are straight lines as seen from the outside surface sides of linking arm sections 15c of a yoke 12c, are formed on the outside surfaces of the linking arm sections 15c. When an excessive torque acts and the linking arm sections 15c are plastically deformed, the protrusions 20 change from a straight line to a non-straight line. From this change it is possible to easily confirm that an excessive torque has been applied to a cross universal joint that includes this yoke 12c. Moreover, when the space between the inside surfaces of the linking arm sections 15c is taken to be D, and the length in the axial direction of the linking arm sections 15c is taken to be L, the dimensions of the parts of the yoke 12c are regulated so that the relation 3
