Abstract: A slide portion of a first adapter is fitted into a slot of a second adapter, and a ball is disposed between a cam member supported by the slide portion and an opening edge portion constituting the slot. The ball can advance toward or retreat from an engagement groove of the opening edge portion by movement of the cam member. By operating a release button connected integrally with the cam member and also sliding the first adapter and the second adapter relative to each other, the ball retreats, and the first adapter and the second adapter are separated from each other.

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.

Abstract: A guide mechanism (10) is provided with: a guide member (72) having a first groove (81); a slide member (74) having a second groove (82); and rolling bodies (76) arranged in a guide groove (98) comprising the first groove (81) and the second groove (82). A stopper (100) for preventing the rolling bodies (76) from moving out of the guide groove (98) is affixed to the second groove (82) by welding. A method for manufacturing the guide mechanism (10) includes a welding step in which the second groove (82) and the stopper (100) are welded by resistance welding while the stopper (100) is pressed against the second groove (82).

Abstract: A cylinder guide mechanism includes a floating bush, a holding part that holds the floating bush, and a linear guide. When a working fluid is supplied in a tube and a piston rod moves back and forth, the floating bush and a guide member of the linear guide move back and forth in the same direction. At this time, a slider of the linear guide is displaced relative to the guide member by retaining the same position. The slider is connected to the tube via an L-bracket.
