PURPOSE:To improve the assembling accuracy to a circuit board, by deflecting the flange parts of the stator core of the motor, and by pressing bownward the flange parts of the housing of the motor on the circuit board, and further, by fixing the housing of the motor on the circuit boad. CONSTITUTION:Flange parts 11A, 11B, 11C formed on the inner peripheral surface of a stator core 9 are superimposed respectively on flange parts 6A, 6B, 6C formed on the outer periphreral surface of a housing 5. Then, into screw holes 13A, 13B, 13C of the flange parts 11A, 11B, 11C of the stator core 9, screws 14 are so inserted respectively as to be contacted with a respectivel protruding parts 12A, 12B, 12C, and they are driven respectively into screw holes 2 of a circuit board 1. As a result, the flange parts 11A, 11B, 11C of the stator core 9 are deflected, and by the uses of the elastic forces caused by these deflections, the respective flange parts 6A, 6B, 6C of the housing 5 are pressed downward on the circuit board 1, and thereby, the housing 5 is fixed on the circuiy board 1. |
