HEATER ELEMENT FIXING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a heater element fixing structure in which both a pipe and the surface of a heated member having the pipe fixed thereto can be efficiently heated by a simple structure. SOLUTION: There are provided a heater element 1 and a heated member having a pipe 75 fixed at its surface, the heater element 1 and the pipe 75 are held by a fitting 40 under a state in which a pipe abutting surface 13 arranged at the outer circumference of the heater element 1 is being abutted against the pipe 75. The heater element 1 causes the pipe abutting surface 13 to be abutted against the pipe 75 and concurrently causes the case abutting surface 15 arranged adjacent to the pipe abutting surface 13 to be abutted against the surface of the heated member with a fitting 40. The heater element 1 is provided with an engagement part 17 engaged under a state in which one end 41 of the fitting 40 is not abutted against the surface of the heated member. The engagement part 17 is constituted by a notch having a depth more than a thickness of the fitting 40 at the case abutting surface 15.
