A clutch mechanism body has a rotational drive force output portion installed in a rotational drive force input system, a rotational drive force input portion installed in a rotational drive force output system, and a pressing mechanism portion for bringing the rotational drive force output portion and the rotational drive force input portion into contact with each other by pressing them. The pressing mechanism portion has constant load means and variable load means that produce pressing forces that bring the rotational drive force output portion and the rotational drive force input portion into contact with each other. A load value produced by the constant load means is set to a value less than a maximum slip limit value that is required to transmit a rotational drive force with the rotational drive force output portion and the rotational drive force input portion held in contact with each other. |
