To resolve the occurrence of abnormal noise from a laminated yoke due to rotation. A first yoke 120A is disposed on one side of a coil bobbin 110 in an axial direction thereof and a second yoke 120B is disposed on the other side of the same, to configure a stator main body 101A. A first holder 160A is disposed on the other side of the stator main body in the axial direction thereof, a second holder 160B is disposed on the one side of the same, a tip 121a of an outer circumferential side magnetic pole part 121 of the first yoke is disposed in a retaining groove 163 of the first holder, and a tip 121a of an outer circumferential side magnetic pole part 121 of the second yoke is disposed in a retaining groove 163 of the second holder. The tip of each outer circumferential side magnetic pole is clamped tightly by a pair of holding walls 162 provided on both sides of each retaining groove 163.
