Abstract
During a released state of a clamping apparatus (4), a predetermined contact gap (B) is formed between a support surface (S) of a reference block (R) and a supported surface (T) of a movable block (M). By switching the clamping apparatus (4) from the released state to a locked state, an output member (31) provided to the reference block (R) causes, through an engaging member (34), the movable block (M) to move towards the reference block (R), thereby contacting the supported surface (T) to the support surface (S). A fluid coupler (8) has a butting contact stroke for ensuring an open state with a predetermined opening, which is set to a value not more than a dimension of the contact gap (B), and is structured so that, during the released state, respective leading end portions of a first joint (61) and a second joint (62) contact each other. Thereby, when the clamping apparatus (4) is switched to the locked state, the fluid coupler (8) is switched to the open state with the predetermined opening.
