Claims

[Scope of utility model registration request]

A shape memory alloy spring is separated into a coiled main body and hook parts at both ends, and the hook parts at both ends are composed of separate synthetic resin hook bodies, and the synthetic resin hook body is composed of a hook member and a coil. an end holding member of a shaped body, the hook member has a hook portion at an upper portion and a fitting leg portion at a lower portion, and the holding member has a central fitting hole into which the fitting leg portion of the hook member is tightly fitted; There is an annular holding groove formed on the outside of the hole to hold the ends of the coiled body. A hook structure for a shape memory alloy spring, characterized in that the hook body is fixed to both ends of a coiled main body by tightly fitting the fitting legs of the spring.
