とを特徴とする逆転防止機構。 an input wheel that can rotate forward or reverse around its axis; and an input wheel that is constantly meshed with this input wheel and rotates forward or reverse around its axis as the input wheel rotates forward or reverse, and simultaneously rotates the axis of the input wheel. It includes a driven wheel that moves in the forward or reverse direction along a central circular arc, and a stopping member that engages with the driven wheel and prevents it from reversing when the driven wheel moves in the opposite direction. A reversal prevention mechanism characterized by:
