摘要：PROBLEM TO BE SOLVED: To stabilize fixation of a stator on a housing without causing deterioration in assembling workability and an increase in manufacturing cost. SOLUTION: A plurality of thin plates 63 stacked on a stator 55 are grouped into a first stack group 59 and a second stack group 61, and concave portions 59a, 61a provided on the external circumferential surfaces of the stack groups 59, 61 are superimposed in a state of shifted in a circumferential direction to configure the stator 55. In fixing the stator 55 in the inside of a rear housing 3 of a motor 20, long bolts 57 penetrating through the entire length of the stator 55 are sequentially inserted into bolt insertion holes 59b of the first stack group 59 and bolt insertion holes 61b of the second stack group 61 and fixed on fixing portions 3a of housing. Short bolts 58 penerateable through only at least the first stack group 59 are inserted at the bolt insertion holes 59b of the first stack group 59 of positions corresponding to concave portions 61a of the second stack group 61 and fixed on fixing portions 3b of the rear housing 3.
