Abstract
A blower which uses a rotation prevention member in which a rotating shaft with circular cross section is press-fitted is disclosed. The blower includes a scroll housing, a resin-made stator which is press-fitted on a rotating shaft with circular cross section, and a centrifugal fan which has a boss inserted on the stator, a cone extending from the boss, and blades extending from the cone, in which the stator and boss are a tubular members. A stator engagement part is formed in a stator outer circumferential face. The stator has a first weld face which extends substantially perpendicular to an axial direction of the rotating shaft, and second and third weld faces which are arranged to extend in the axial direction. A boss engagement part is formed in an inner circumferential face of a boss through hole and engages with the stator.
