PURPOSE:To improve an operation characteristic by a method wherein a printed circuit board having the arrangement of operating circuit components for a motor is assembled in a controller case and a controller case fixing seat is fixed to a controller supporting boss part arranged at a base part. CONSTITUTION:Operating circuit components for a motor 12 are arranged in a printed circuit board 39, and a controller case 42 having a button 41 of plastic movable piece is assembled on the upper part of a tact switch 40 for generating a light current signal. Then, it is made as a controller assembly in which the printed circuit board 39 is screw fixed to the controller case 42 and screw fixed to a controller supporting boss part 45 of a base 10. Under an assembled state of a main body 1, an operating panel 7 of a frame 8 joins to the upper surface of the controller case 42. A controller guiding rib 46 for performing a positive connection is formed at the frame 8. |
