Abstract:
1. A motor protector that puts, in an open state, an electric contact of a conduction circuit for an electric appliance when a temperature of the electric appliance exceeds a predetermined temperature, the motor protector being provided with an insulating resin case including an opening sealed by a sealing member, a base member stored in the insulating resin case, and components held by or integrally incorporated in the base member, the motor protector comprising: a serial current path that includes a second resistor one end of which is connected to the first terminal via a conductive bottom plate, the second resistor being connected to the movable contact via the movable plate and the intermediate fixing plate and being connected in parallel to the serial current path, wherein the first resistor is arranged in a manner such that a longer direction extends in a direction orthogonal to a direction in which electricity flows through the movable plate, the first resistor is connected in a manner such that two ends of the longer direction form a bridge between the first and second electrode sections, and the first resistor is arranged in a manner such that an intermediate portion of the longer direction is inserted into a gap formed between the second resistor and an inside position with respect to a portion at which the movable contact of the movable plate is formed.
