Claims

[Scope of utility model registration request]

A temperature-sensitive pellet, a compression spring, and a movable contact are housed in a metal case, and the opening of the metal case is closed with an insulating bushing through which a lead wire with a fixed contact is inserted at the inner end, and the metal case protrudes from the insulating bushing. In a temperature fuse formed by caulking the parts toward the central axis and coating the outer surface of the insulating bushing with a sealing resin, the protruding part of the metal case has a bent part along the outer surface of the insulating bushing and a protrusion in the axial direction. A temperature fuse characterized by having a section.
