Abstract

A compliance unit includes a return piston that causes a first body and a second body to return to a home position and a locking mechanism that locks the return piston in the home position. The locking mechanism includes a locking member that is capable of being freely displaced to a locking position where the locking member is fixed in place by being in contact with the return piston and to a non-locking position where the locking member is not in contact with the return piston and is not fixed in place, a locking spring that presses the locking member toward the locking position, an unlocking piston that presses the locking member toward the non-locking position, an unlocking pressure chamber that causes the unlocking piston to generate thrust, and an unlocking port for supplying air to the unlocking pressure chamber.
