Thermal protector

A thermal protector that is used by being arranged in a flow channel of hot air of an electrical apparatus generating hot air and that opens and closes an electric circuit of the electrical apparatus, the thermal protector comprising:

• a fixed contact coupled to a first terminal that is connected to an external circuit;
• a movable contact that is arranged at a position facing the fixed contact;
• a bimetal that inverts a bending-back direction treating a set temperature as a boundary;
• a movable plate that is engaged with the bimetal, that has one end fixed to the movable contact, that has the other end coupled to a second terminal that is connected to another external circuit so that the movable contact is brought into contact with the fixed contact by an elastic force, and that is fixed to a holding portion of a base in a cantilevered manner;
• and
• a bent plate plane formed by being bent at a prescribed angle from a plate plane of the movable plate in a side portion of a tip side from a center portion of the movable plate in a vicinity in which the movable contact of the movable plate is arranged, wherein
• the bent plate plane limits an air flow of a contact part of the fixed contact and the movable contact when the contacts are open by being formed by being bent from the movable plate in a direction in which the fixed contact exists or adjusts a flow direction of hot air so that the flow direction becomes in a fixed direction that is parallel to a longitudinal direction of the movable plate by being formed by being bent from the movable plate in a direction opposite to a. direction in which the fixed contact exists.
