In addition, a fixing plate constituting a part of the above internal chassis, the insulating member, the flange portion and the indicating lamp cover are clamped with clamping members fed through through-holes provided therethrough, with the above insulating member being held between the fixing plate and the indicating lamp cover. Cylindrical spacers each having a predetermined length and an internal diameter, and into which and from which the above bolt can be freely inserted and taken out, are fitted to the through-holes. The length of the spacers is set to the most suitable value so as to provide the most suitable clamping conditions corresponding to such considerations as the type of the insulating member and the type of vibration from which the electric lamp and electric control board are to be insulated.
