Claims

[Scope of utility model registration request]

a coiled spring body cut to a predetermined length and subjected to shape memory treatment at a predetermined temperature and time; a core member formed such that its ends can be fitted into both open ends of the spring body; The core member is fitted to the outer periphery of both ends of the spring body through the spring body so as to overlap with the fitting portion of the core member into the spring body, and the inner diameter is expanded by an external force, and the elasticity is increased by releasing the external force. A hook device for a shape memory alloy spring, comprising a clamp member formed of a substantially annular leaf spring capable of tightening both ends of the spring body with the core member by restoring force.
