PURPOSE:To quickly accomplish straight slide and turning slide of a shaft in a simple and light structure by supporting a roller on one side of a shaft and moving the roller along the respective contact surfaces of guide plates of two kinds sequentially. CONSTITUTION:A roller 14 is rotatably mounted through a pin 15 on one side of a shaft 11 capable of turning and sliding. There is provided a guide plate 12 having a guide surface 12a where the roller 14 is brought into contact by tension of a coiled spring 16. A cylindrical guide plate 13 is rotatably fitted outward to the shaft 11, and one side of the shaft 11 is provided with a notch having a vertical guide surface 13a and an inclined guide surface 13b and with a U-shaped metal fitting 18 fixed to a driving shaft 17a of an air cylinder 17, which is coupled thereto through a pivot 19 and a L-shaped metal fitting 20. In this arrangement, the straight slide of the shaft 11 where the roller 14 moves along the guide surface 12a and the turning slide of the shaft 11 where the roller 14 moves along the guide surfaces 12a, 13a, 13b can be selected. |
