Abstract
A three-position control device includes a cylinder device, a fluid control unit, and a displacement restriction device. The cylinder device displaces a piston to each of a retracted position, an intermediate position, and an advanced position. The cylinder device has a first fluid chamber for retraction and a second fluid chamber for advance. A fluid control unit switches an advanced/retracted position of the piston. A second working pressure during displacement from an intermediate position to the advanced position is set to be greater than a first working pressure during displacement from the retracted position to the intermediate position. The displacement restriction device has a load receiving portion and a biasing means. A biasing force of the biasing means is set to be greater than a thrust caused by the first working pressure and smaller than a thrust caused by the second working pressure.
