Air chuck

An air chuck comprising:

• a finger support part including a pair of fingers that is openable and closable;
• a chuck main body part including an operation mechanism operable to open and close the pair of fingers;
• and linking mechanisms that detachably link the finger support part to the chuck main body part, wherein
• the finger support part includes a pair of lock shafts that shifts between a lock position and a non-lock position, the pair of lock shafts shifts to the non-lock position so as to render the pair of fingers capable of being opened and closed when the finger support part is linked to the chuck main body part, and the pair of lock shafts shifts to the lock position and locks the pair of fingers so as to render the pair of fingers incapable of being opened and closed when the finger support part is detached from the chuck main body part, and
• each lock shaft of the pair of lock shafts is provided with a corresponding one of the linking mechanisms, and when the finger support part is linked to the chuck main body part, each of the linking mechanisms causes the corresponding lock shaft to shift from the lock position to the non-lock position and links the finger support part to the chuck main body part via the lock shaft.
