PURPOSE:To improve positional accuracy of a rotary shaft of a motor in an apparatus in which the motor is mounted. CONSTITUTION:Positioning holes 21b, 21c having a predetermined positional relation are provided in mounting target positions of a spindle shaft 22 in a frame 20. A reference hole 33a is formed along an axial. direction at a spindle shaft 33. A shaft side pin 43 to be engaged with the hole 33a, and a positioning jig 40 having a predetermined positional relation to the pin 43 and frame side pins 41, 42 to be engaged with the holes 21b, 21c, respectively, are formed. The pin 43 is engaged with the hole 33a, the pins 41, 42 are engaged with the holes 21b, 21c, respectively, and the jig 40 is mounted on the frame 20 and a board 30. The shaft 33 is arranged in a mounting target position to the frame 20 by the jig 40, and the board 30 is secured in the position.
