Claims

[Scope of Claim for Utility Model Registration] A wax-type thermally-responsive body containing wax that expands and contracts in response to changes in the temperature of an object to be detected and that is equipped with an actuating part that operates based on changes in the volume of the wax; 1. A wax-type thermally-responsive body, characterized in that an elastic piston is provided in a chamber, and a biasing mechanism is provided for biasing the elastic piston toward the wax with a pressure smaller than the excess pressure of the wax in response to the expansion pressure of the wax.
