Claims

[Scope of utility model registration request]

It is composed of a main rotating shaft having internal teeth and a driven rotating shaft disposed coaxially with the main rotating shaft. A plurality of arms extending symmetrically and an engagement protrusion provided at one location of the arm that engages with the internal teeth of the main drive rotation shaft are integrally formed, and the arms are engaged. The protrusion has a flexible piece that is movable between a position where it engages with the internal teeth of the driving rotating shaft and a position where it disengages, and the driven rotating shaft has the above-mentioned position. A pair of pressing pieces that press the arm in a direction that causes the engagement protrusion to mesh with the internal teeth of the driving rotation shaft, and the pressing pieces fall adjacent to each other on both left and right sides in the circumferential direction from the contact area of the pressing piece in the arm. A slip mechanism characterized by having a notch formed therein.
