A temperature fuse is provided above the bimetal, and a temperature fuse is attached to the lower side of the shear sheath, and the curved portion of the fuse, which melts at a temperature above the above-mentioned certain temperature, is provided so as to fit into the through hole of the shear sheath. Overcurrent protector with temperature fuse. (2) The overcurrent protector with a temperature fuse according to claim 1, wherein the temperature fuse provided on the lower side of the chassis is entirely composed of a fuse. (3) The overcurrent protector with a temperature fuse according to claim 1, wherein only the curved part of the temperature fuse provided on the lower side of the chassis is a fuse, and the other part is an electric resistance piece. (4) The upper terminal connected to the end of the movable contact piece on the side opposite to the side where the movable contact is provided and the lower terminal connected to the end of the temperature fuse on the side opposite to the side connected to the fixed contact are parallel to each other. A protector with a temperature fuse according to claim 1, 2, or 3 of the utility model registration claim, wherein the protector has a plug-in type connecting portion that protrudes outward from the chassis and case.
