Document Type and Number:

WIPO Patent Application WO/2023/085395

Kind Code:

A1

Abstract:

A state is assumed where as an output member (4) rotates in a predetermined direction, a pair of pressing surfaces (13) are pressed against a surface (6) to be pressed, and as an input member (3) rotates in the opposite direction to the predetermined direction, an input-side engaging part (9) is engaged with an input-side engaged part (17); in this state, a second direction distance (D1) between the rotation center (O) of the input member (3) and a contact portion (Pin) between the input-side engaging part (9) and the input-side engaged part (17) is made greater than a second direction distance (2) between the rotation center (O) of the output member (4) and a contact portion (Pout) between an output-side engaging part (12) and an output-side engaged part (14). In a lock state or semi-lock state, a contact portion (C1) between the output-side engaging part (12) and the output-side engaged part (14) is positioned closer to the rotation center (O) of the output member (4) in a first direction than a virtual straight line (L) connecting the rotation center (O) of the output member (4) and the contact portion (C2) between the surface (6) to be pressed and one of the pair of pressing surfaces (13).
