る熱形過負荷継電器。 A shifter that transmits displacement of the bimetal due to overcurrent, a release lever that is engaged at one end of the shifter and rotated via the shifter by the displacement of the bimetal, and a release lever that is engaged with the other end of the release lever. A thermal overload relay comprising a reversing spring that reverses when it rotates beyond a dead center, a movable contact that connects and separates due to the reversing action of the reversing spring, and a contact mechanism having a fixed contact, wherein the reversing spring is fixed. A thermal overload relay characterized in that a protrusion is formed on the side of the case and a support piece is fixed thereto, and the elasticity of the reversal spring is used to press fit the protrusion and the support piece into a case to fix the reversal spring.
