PURPOSE:To prevent the vibration of an angular bearing while it is being rotated and improve the rotational life of the bearing by using a bush with the bearing structure in a receiving section for the retainer spring of the bearing. CONSTITUTION:A bush 8 with the ball bearing structure in which a part of a support axis 1 forms an inner race is provided as a retainer an angular bearing 2. By using the bearing-type bush 8 like this, even when the support axis 1 is expanded by heat, the support axis 1 and the bush 8 make mutual sliding motion easily and constant thrust force is steadily actuated on the angular bearing 2 and then a constant preset pressure is applied. As a result, the reduction of vibration and rotational life of the bearing 2 can be promoted and improved respectively. |
