Abstract

A stator (19B) includes a stator core (20) including a plurality of teeth (20B) protruding inward from an inner peripheral surface of an annular yoke (20A) centered on an axis in a radial direction, a bobbin (30), and a coil (40) having a winding wound on the teeth (20B) and the bobbin (30). The respective teeth (20B) have a non-constant width portion of which a length in a circumferential direction changes as it goes in the radial direction. The bobbin (30) has a winding length adjustment portion (36) which is formed at a position corresponding to the non-constant width portion, reduces a winding length which is a length of the winding around the support portion as a length of the respective teeth (20B) in the circumferential direction increases and increases the length as the length of the respective teeth (20B) in the circumferential direction decreases.
