Claims

[Claims for Utility Model Registration] A metal case with a stepped portion formed on the inner surface, a temperature-sensitive pellet housed in the metal case, a high-pressure cotton spring, and a movable contact; an insulating bushing having an engagement step that engages with the step; a lead wire passing through the insulating bushing and having a fixed contact at an inner end contacting the movable contact; and a lead wire between the insulating bushing and the movable contact. In a temperature fuse having a weak compression spring interposed therebetween, the metal case is provided with a cylindrical part with a small outer diameter and a cylindrical part with a large outer diameter, and an insulating bushing is engaged at an intermediate position between the two. A temperature fuse characterized by forming a matching stepped portion.
