PROBLEM TO BE SOLVED: To improve the adaptability of operation and commonality and versatility of manufacture by forming a slide mechanism with three links each base end of which is connected to the middle supporting point and with which a Y-shape is formed as the whole, connecting a slide to the tip of the link which is lower than the middle supporting point and transmitting driving motion to the lower link through the upper link and via the middle supporting point. SOLUTION: Each base end of a 1st link 12, 2nd link 14 and 3rd link 16 is freely rotatably connected at the middle point 11 and a Y-shaped link mechanism (slide driving mechanism) 10 is formed. The tip of the 1st link 12 is taken as the supporting point (movable supporting point) 13 and the tip of the 2nd link 14 is taken as a freely rotatable supporting point (fixed supporting point, movable supporting point) 15. The movement ST of the supporting point 13 moves the movable supporting point 17 at the tip of the 3rd supporting point 17 to SST1-SST3 through the 2nd link 12 and via the middle supporting point 11. When the motion pattern of the supporting point 13 is changed, the movable supporting point 17 executes various motions. The reaction force of the load is distributed to the supporting point 13 and the supporting point 15.
