PROBLEM TO BE SOLVED: To prevent vibration of a stator core that is formed from a plurality of core constituent members, from being transmitted to a center piece that supports the stator core.SOLUTION: A blower motor M includes a stator 10. The stator 10 includes: a stator core 42 that includes a plurality of core constituent members 48U-48W' each including a yoke 52 including an engaging part 56 and an engaged part 58, and teeth 50, and that is formed by engaging the engaging part 56 of one core constituent member 48U-48W' to the engaged part 58 of the other core constituent member 48U-48W'; a press-fitting member 90 that is press-fitted into a shaft center of the stator core 42; and a coil 74 that is formed by winding a winding wire 46 around the teeth 50. The blower motor M also includes: a rotor 12; a center piece 14 that supports the stator 10 and the rotor 12; and a vibration-proof member 92 that is interposed between the press-fitting member 90 and the center piece 14.SELECTED DRAWING: Figure 12 【課題】複数のコア構成部材によって構成されたステータコアの振動が当該ステータコアを支持するセンタピースに伝達されることを抑制する。【解決手段】ブロアモータＭは、係合部５６及び被係合部５８を有する継鉄部５２と、ティース部５０と、を有する複数のコア構成部材４８Ｕ〜４８Ｗ'備え、一のコア構成部材４８Ｕ〜４８Ｗ'の係合部５６を他のコア構成部材４８Ｕ〜４８Ｗ'の被係合部５８に係合させることによって構成されたステータコア４２と、ステータコア４２の軸心部に圧入される圧入部材９０と、巻線４６がティース部５０の回りに巻回されることによって形成されたコイル７４と、を含んで構成されたステータ１０を備えている。また、ブロアモータＭは、ロータ１２と、ステータ１０及びロータ１２を支持するセンタピース１４と、圧入部材９０とセンタピース１４との間に介装された防振部材９２と、を備えている。【選択図】図１２
