PROBLEM TO BE SOLVED: To easily attach a driven body having couplings. SOLUTION: The device has the driven body 41 which is attached/detached to/from the device body 40. The driven body 41 has the coupling 10 on the drive side, which is provided on the device body 40, and the coupling 20 on the follower side, which is connected to the coupling 10. Both the couplings are extended axially and respectively have recesses 11 and 21 and projections 12 and 22, which are adjacent to each other in the circumferential direction of the couplings. When the driven body is attached to the device body, the couplings are connected to each other, while one of the couplings is rotated at a low speed, relative to the other coupling. |
