Abstract: A brushless motor is smaller, flatter, and lighter but is easy to assemble and has reduced motor vibration. An attachment base is integrally molded by two-color extrusion molding using a first resin material that forms a base main portion and a second resin material that forms a support portion and is softer than the first resin material.

Abstract: A blower motor can efficiently remove heat generated by all substrate-mounted components. A rotor and a stator are housed inside a motor case. A motor substrate on which a motor driving circuit is formed is disposed in a space formed in the axial direction between (i) the rotor and the stator and (ii) an opening bottom portion of a bracket. A heat-generating component mounted on the motor substrate contacts the opening bottom portion of the bracket via a heat-dissipating member.
