Abstract
Linear-type sheathed heaters are arranged substantially in parallel with each other in a case body. Regions near the ends of the outer peripheral surface of each of the sheathed heaters are held by elastic holding members so as to move in the axial direction. A cylindrical space is formed between the outer peripheral surface of each of the sheathed heater and the case body. A space is provided that communicates the cylindrical spaces.
