PURPOSE:To enable to control the axial position of a rotational shaft after assembled by providing a prepressurizing washer on the end face of an outer wheel in one bearing and providing a lever member for pressing against the washer on the end face of the outer wheel in the other bearing. CONSTITUTION:A rotational shaft 1 is supported through bearings 2, 3 to brackets 4, 5, and a ring-shaped prepressurizing washer 6 for axially performing a spring action is provided between the end face of the outer wheel of one bearing 2 and a bearing housing 4a of the bracket 4. Further, an arcuate-shaped lever member 8 which makes contact with the end face of the outer wheel of the bearing 3 is provided through an annular liner 7 between the other bearing 3 and the bearing housing 5a of the bracket 5. The shaft 1 can be moved axially by pressing the end of the member 8 by a screw 9 spirally engaged from the exterior. |
