PURPOSE:To easily perform a position aligning control by mounting a cam follower shaft to a bearing unable to move to the inner direction and mounting by a thread an adjusting ring, which provides a bearing hole having a stepped difference supporting an outer directed face of the bearing, to an internal thread hole provided in a case wall structure. CONSTITUTION:A hole 29 is concentrically provided in boss parts 27, 27 in a wall structure mutually opposed to a case 6. The hole 29 forms an internal thread hole 10 and a guide hole 31, providing a step difference, in the outer of the hole 10. An adjusting ring 14 is formed having a thread part 35, coming into thread contact with the thread hole 10, in a guide part fitted to the guide hole 31, while a bearing hole 13, fitting a bearing 7, is formed. Accordingly, an output shaft 5, having a cam follower 4 rotatably supported to the bearing 7, is unable to move in the inner direction, while the adjusting ring 14 enables a position with a cam 3 to be adjusted by adjusting the thread part 35 in the same direction. In this way, a control of position alignment can be easily performed while its accuracy can be correctly attained. |
