<p>The present invention has an object of providing a retractor for realizing a stable retracted state with a small number of operations. A retractor including a central fixed portion 30a, an extended arm portion 30b extending on both sides of the central fixed portion 30a, and a hook support section 40 which is attached to the extended arm portion 30b so as to be slidable in a longitudinal direction and supports a retractor hook 50 is formed of a plastically deformable composite member for, when receiving a deformation load of causing a bending deformation, permitting the extended arm portion 30b to be plastically deformed in an in-plane direction Fh in a virtual plane F, which is formed of the central fixed portion 30a and the extended arm portion 30b, while restricting the extended arm portion 30b regarding the deformation in an out-of-plane direction Fv.</p> |
