Since the connection portion of the heating wire is placed up and down, the size of the vertical frame body 30 can also be reduced.

Since the one end portion 40a and the other end portion 40b of the heating wire 40 are housed in the left housing recess 50 and the right housing recess 54 located on both side surfaces of the heat insulating member 38, the size of the vertical frame 30 can be reduced, and the fixing can be surely fixed. Both end portions 40a, 40b, and their assembly work becomes easy.

The both end portions 40a and 40b of the heating wire 40 that are drawn after the heat insulating member 38 are connected to the first wire 44 and the second wire 48 by the first connecting portion 42 and the second connecting portion 46, respectively, so that the heat can be insulated The joining operation of the rear surface of the member 38 makes assembly work easy.

Since the protective member 58 is covered by the second lead wire 48 passing between the first connecting portion 42 and the second connecting portion 46, the heating wire 40 is not scratched or the like. Moreover, since the heating wires are adjacent, the assembly workability is improved.

Further, since the first lead wire 44 and the second lead wire 48 are taken out from one lead-out hole 72, the size of the vertical frame body 30 can be reduced, and the assembling workability can be improved.
