Abstract
A forward-moving inching unit and a backward-moving inching unit are built in a casing (1) which is slidable relative to a guide member (b). Each of the inching units is made up of an inching piston (60), a brake piston (61) disposed in a direction opposite to the inching piston (60), a lock member (62) disposed between the inching piston (60) and the brake piston (61) to tighten the guide member (b) when pinched between both the pistons (60, 61), a spring (63) for urging the pistons (61) to the right/to the left, a first pressure chamber (64) for pressing the brake piston (61) to the right/to the left, a second pressure chamber (65) for pressing the inching piston (60) in the opposite direction, and a valve block (2) for inputting, at the time of forward-moving inching, a fluid pressure into the second pressure chamber (65) of the forward-moving inching unit and the first pressure chamber (64) of the backward-moving inching unit and for inputting, at the time of backward-moving inching, the fluid pressure into the second pressure chamber (65) of the backward-moving inching unit and the first pressure chamber (64) of the forward-moving inching unit.
