Abstract
A stator includes a core back that has an annular shape and that extends in a circumferential direction about a central axis that extends in a vertical direction, teeth that extend in a radial direction from the core back, bobbins attachable in the radial direction to the teeth, and coil wires wound around the bobbins. The bobbins each include a cylindrical portion that extends in the radial direction and a protrusion that protrudes in the radial direction from an upper end portion of the cylindrical portion on a core back side and that is fixed to the core back.
