The present invention provides a robot hand tool coupling device (1) that can reliably prevent the loss of the joining member, reduce the number of parts and simplify the structure, maintain low manufacturing costs, and increase the durability of the device. A locking mechanism (4) is equipped with: an actuation shaft (14) that is driven between a lock position and a release position by an air cylinder; a retainer (17) that surrounds the outer perimeter of the actuation shaft (14); a plurality of rod insertion holes (18) that are formed in an inner perimeter wall (17c) of the retainer (17); a ring-shaped groove (31); a plurality of push rods (19) that are attached movably in the plurality of rod insertion holes (18) and that transfer the output of the actuation shaft (14); and a plurality of arc-shaped locking members (20) that are slidably attached in the ring-shaped groove (31) and that are in contact with the ends of the push rods (19). <IMAGE> |
