PURPOSE:To minimize troubles of disconnection of a feeder cord or the like, by arranging an inner wire member and a feeder cord for feeding current to a motor in the vicinity of the center of pivotal movement of a motor supporting means, and thereby reducing expansion, contraction, bending, etc. of the inner wire member and the feeder cord that is caused by vertical oscillation of the motor. CONSTITUTION:An inner wire member 71 is extended from a connecting portion 84 formed on the left-side upper surface of a main upper wall 81a of a cover member 81 to a hollow space 41 formed between a front cover 13 and a motor 11 on the right side thereof, so that it can be arranged to have a relatively large radius of curvature. Resultantly, it is enabled to reduce the sliding resistance of a wire 101 that is moved through the inside of the inner wire member 71 and hence to reduce the force required for actuating a control knob (not shown). Further, since the inner wire member 71 and a feeder cord 70 are both arranged in the vicinity of the center of vertical oscillation of the motor 11, it is enabled to minimize extension, contraction, bending and lateral movement of the member 71 and cord 70 that is caused by the vertical oscillation of the motor 11, so that troubles of disconnection of the member 71 and the cord 70 can be minimized. |
