PURPOSE: To circulate lubricating oil positively regardless of the relative rotating direction of the end bearing of a one-way clutch and inner-outer rings. CONSTITUTION: The inner peripheral surface 121 of an end bearing 12 having the inner peripheral surface 121 and the outer peripheral surface 122 is provided with spiral lubricating oil grooves 123A, 123B different in the inclined direction, and if necessary, dynamic pressure generating grooves 125 of symmetric shape (rhombic shape in a figure) from the circumferential view are added. |
