ストが増大すると共に、作業性も低下する。 The lead wires of the heater are drawn out to the lower surface of the heat shield through a recess formed in the periphery of the heat shield, and are routed to a terminal insulating board provided at the center of the heat shield. Since other lead wires are also wired on the lower surface of the heat shield plate, it is necessary to cover the heater lead wires with an insulating tube or the like to avoid contact with these wires. However, heater lead wires, such as mica heaters, are usually made of bare wires, so if they are covered with an insulating tube or the like, the cost will increase accordingly, and workability will be reduced. descend.
