PURPOSE:To improve workability and to reduce the number of component parts by setting a distance between a motor output shaft and a reference shaft through a positioning means and by fixing the motor through filling with an adhesive. CONSTITUTION:A pitch gauge 9 is placed over between an output shaft 4a of motor 4 fitted in a motor-fitting part 2a and a gear-supporting shaft (reference shaft) 5b fixed in a case 2 of an intermediate spur gear 5a, and a fixing position of the motor 4 is set so that there is a given space between the output shaft 4a and the gear-supporting shaft 5b. Then, said state is maintained, and an adhesive-filling part 8 and a semicircular tubular vertical wall part 8a are filled with a thermosetting adhesive 12 which is solidified to fix the motor 4 to the motor-fitting part 2a. Therefore, because complicatedness at the time of fixing of the motor is solved, workability of said motor are improved and reduction of production cost is made possible, since parts such as screw are not required.
