A backlash clutch comprising first rotation member (3) and a second rotation member (4), each of which are provided rotatably on an identical axis, and are engaged together in a rotating direction of the members by contacting each radial extension surface (3a, 4a). A gap d exists between said radial extension surface of the first and the second rotation members (3a, 4a) at the rotating direction of the members. |
