PURPOSE:To provide a holding device which is simple in construction, shows a position safety characteristic and facilitates more a removing operation thereof by a method wherein a U-shaped recess is formed at an electrical heating device frame fixing part at its screw side, the device is screw set through a resin integral formed bushing inserted in perpendicular to the direction of screw and the frame bent shape of the other supporting rubber fixing part is formed as an inverted U-shaped. CONSTITUTION:An entire shape of an insulation bushing 9 is made as a U-shape, an outer circumference of the insulation bushing is provided with a flange for keeping an insulation distance. A groove 10 having a width corresponding to a plate thickness of the electrical heater device frame is arranged at the outer circumference and then a recess 13 is arranged at the end part. The fixing direction of the bushing 9 is fixed by the groove 10 and the threaded hole which is conventionally made as a through-pass hole is formed as a recess 11 of U-shape, so that the making of the insulation bushing can be facilitated. The electrical heater fixing part is provided with a U-shaped recess 12 and the inner end part of the U-shaped recess 12 is provided with the projections 14. The bushing 9 to be inserted into the recess 12 is pushed by the projections 14 in the midway of the insertion and resiliently deformed and then the bushing 9 is not easily removed under a complete fitted condition due to a fitting of the projections 14 is the groove end recess 13. |
