Abstract
A chuck mechanism operates a piston in a cylinder tube by using action of compressed air and opens and closes, by using a rod coupled to the piston, a pair of fingers, thereby gripping work W. The locking mechanism locks the fingers at work grip positions. The locking mechanism includes a first locking member, a second locking member, and a drive device. The first locking member is displaced when the pair of fingers are opened or closed. The second locking member retains the first locking member so as to lock the fingers at the work grip positions. The drive device relatively displaces the first locking member and the second locking member to locking positions and non-locking positions.
