PROBLEM TO BE SOLVED: To prevent a resin from easily leaking to the outside during resin molding while easily removing the resin leaked out.SOLUTION: In the stationary member 40 of a stator, a through hole 43 (radial groove 44 and axial hole 45) having an L-shaped cross-section, which bends in the middle of extending from the inside to the outside of the radial direction of the stator 30 on a contact surface 42a in contact with the stator core 30 and extends to the outside of the axial direction of a stator core 30, is formed. Therefore, since a resin flowing into the through hole 43 (radial groove 44) easily stays in a bent portion (connection part to the axial hole 45) during resin molding, the resin can be prevented from being leaked to the outside. Also, when removing the resin leaked to the outside from the through hole 43, a fixture is prevented from interfering with a terminal 50 bending toward the inside of the axial direction of the stator core 30, and the resin can be thereby easily removed.SELECTED DRAWING: Figure 4 【課題】樹脂モールドの際に外部に樹脂を漏れ出にくくすると共に漏れ出た樹脂を容易に除去可能とする。【解決手段】ステータの固定部材４０に、ステータコア３０との接触面４２ａでステータコア３０の径方向の内側から外側に延びる途中で屈曲してステータコア３０の軸方向の外側に延びる断面Ｌ字状の貫通孔４３（径方向溝４４と軸方向孔４５）が形成されている。このため、樹脂モールドする際に、貫通孔４３（径方向溝４４）に流入した樹脂は屈曲部（軸方向孔４５との接続部）に溜まりやすくなるから、外部に樹脂が漏れ出るのを抑えることができる。また、貫通孔４３から外部に漏れ出た樹脂を除去する際に、ステータコア３０の軸方向の内側に屈曲している端子５０に治具が干渉するのを防止して、樹脂を容易に除去することができる。【選択図】図４
