<p>PURPOSE:To miniaturize a device by performing the changeover of a mode without using a plunger by rocking a lever by two cams rotating in an opposite direction each other and selectively driving a loading ring and slider. CONSTITUTION:The cams 19, 20 rotating in the opposite direction each other are provided on a shaft 18 and the lever 25 rotatably engaging with these by a pin 35 is provided. When, now, the cams 19, 20 are rotated, the locking pin 36 at the tip of the lever 25 is rocked, by driving a ring 1 and slider 2 selectively by engaging with either the locking parts 37, 38 of the ring 1 for loading or the locking part 39 of the slider 2 for braking. In the case of the shown figure, for instance, the locking pin 36 is engaged with the locking part 38, so the ring 1 is locked and the slider 2 is moved in an X direction. Consequently the miniaturization is realized by performing the change-over of the mode without using a plunger.</p> |
