造。[Claims for Utility Model Registration] (1) A shape memory alloy that is deformed so that the required parts that are separated are separated by a predetermined amount, and as the transformation temperature is reached, the shape memory alloy returns to its original shape. In an apparatus including a temperature sensitive mechanism in which an actuated object is driven by the predetermined portions moving close to each other when deformed, a deformable linear member is provided between the predetermined portions of the shape memory alloy that are separated from each other. 1. A holding structure for a shape memory alloy, wherein the linear member is tensioned, and both ends of the linear member are fixed to the predetermined portions. (2) the shape memory alloy is formed into a coil shape,
2. The shape memory alloy holding structure according to claim 1, wherein the required portions that are separated from each other are both ends of the molded coil, and the wire member is inserted into the coil. (3) The shape memory alloy holding structure according to claim 1, wherein the shape memory alloy is housed inside a shield member having heat insulating properties and flammability.
