Abstract
A motor includes a rotor portion including a shaft and a rotor magnet rotatable about a center axis, an armature arranged opposite to the rotor magnet to generate a torque therebetween, a circuit board arranged below the armature in an axial direction substantially parallel to the center axis and including a control circuit controlling rotation of the rotor portion, and a base portion including a bearing holder which supports the armature on its outer side surface and the shaft on its inner side surface via a bearing member. The armature is pressed against the bearing holder in the axial direction with an elastic member.
