PURPOSE:To reduce the space by disposing pulleys on both ends of a cylinder and fixing wires to both surfaces of a piston so that the wires are connected through the pulleys to a slide member. CONSTITUTION:Pulleys 8a, 8b are disposed on both ends of a cylinder 2a, and wires 9a, 9b are fixed to both surfaces of a piston 3a. The wires 9a, 9b are connected through the pulleys 8a, 8b to a slider 11. In this arrangement, the slider 11 is moved in parallel to the side of the cylinder 11 to remarkably decrease the space. |
