Thereby, the holding plate 90 is fastened together with the insulating plate 86 and fixed to the support plate 74.

  In this fixed state, as shown in FIG. 8, the lead of the resistor 88 is between the free end side of the presser plate 90 pressed by the screw head 92G and the first sandwiching portion 108 of the insulating plate 86. The wire 88B is sandwiched, and the presser plate 90 generates a reaction force due to the free end portion being warped. Due to this reaction force, the holding plate 90 generates a pinching force for pinching the lead wire 88 </ b> B with the insulating plate 86. Thereby, the lead wire 88B of the resistor 88 can be fixed in a state where it is electrically connected to the metal holding plate 90.

  Further, the lead wire 88C of the resistor 88 is sandwiched between the second sandwiching portion 116 provided on the free end side of the insulating plate 86 held by the screw head 92G and the support plate 74, The insulating plate 86 generates a reaction force when the free end is warped.
