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.

10. An air chuck provided with a locking mechanism, the air chuck comprising:
-
a chuck mechanism that operates a piston in a cylinder tube by using action of compressed air and that advances and retracts a rod coupled to the piston so as to open and close a pair of fingers, thereby gripping work; and a locking mechanism that locks the pair of fingers at work grip positions; wherein the locking mechanism includes at least one first locking member that is displaced when the pair of fingers are opened or closed, at least one second locking member that retains the at least one first locking member so as to lock the pair of fingers at the work grip positions, and a drive device that relatively displaces the at least one first locking member and the at least one second locking member to locking positions where the at least one first locking member and the at least one second locking member are retained at each other and to non-locking positions where the at least one first locking member and the at least one second locking member are separated from each other, and wherein the at least one first locking member and the at least one second locking member are displaced to the locking positions and the non-locking positions by relative rotation of the rod about an axial line. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
