PURPOSE:To reduce the manufacturing cost of a race and also to increase load capacity of a radial rolling bearing. CONSTITUTION:The top end edge of a folded cylinder part 16 formed on the inner periphery of a race 12 is made faced to the end surface of the roller 9 of a radial rolling bearing 6. The axial displacement of the radial rolling bearing 6 is prevented by the folded cylinder part 16. The outer peripheral edge of the cage 10 of a thrust rolling bearing 7 is made adjacent to the inner peripheral surface of a folded locking part 15, thereby the displacement in the diametral direction of the thrust rolling bearing 7 is prevented. Thereby, the interference between the radial rolling bearing and the thrust rolling bearing 6, 7 can be prevented. |
