Abstract:
1. A thermal protector for opening/closing an electric circuit with a bimetal having a warpage direction that is inverted at a predetermined temperature in response to a change of an ambient temperature, comprising: a fixed conductor having a fixed contact provided at one end, and a first terminal for an external connection; an insulator, provided between the fixed contact and the first terminal of the fixed conductor, having columns integrally formed by being resin-molded; a movable plate having a fixed part having movable plate holes into which the columns of the insulator are inserted, a movable contact formed at a position facing the fixed contact at an end on a side opposite to the fixed part, and a first hook formed on the movable contact side and second and third hooks formed on the fixed part side; the bimetal, held by the first hook and the second and third hooks of the movable plate, for opening/closing a contact between the movable contact and the fixed contact by inverting the warpage direction at the predetermined temperature; and a resinous block having resinous block holes into which the columns are inserted above the fixed part of the movable plate having the movable plate holes into which the columns are inserted, for fixing the fixed part to the insulator by inserting the columns into the resinous block holes, wherein the movable plate makes the movable contact touch the fixed contact with a predetermined spring property in a normal state, and the movable plate comprises
