<p>PURPOSE:To provide a clutch structure capable of transmitting the rotation only in a fixed range of the relative rotational angle between the input side and output side. CONSTITUTION:Gap holding members 9, 10 rotated integrally with the coupling member of the input side or output side are provided between the coupling member 4 of the input side or the coupling member 6 of the output side. Grooves 12, 13 inserted with the gap holding members 9, 10 in a fixed range of the relative rotational angle between the coupling members 4, 6 of the input side and output side are provided.</p> |
