Abstract

A motor includes a shaft with a central axis along an up and down direction as a center, a bearing mechanism rotatably supporting the shaft; a cylindrical rotor main body fixed to the shaft; a rotor fan fixed to the shaft at an upper side of the rotor main body; an armature facing the rotor main body in a radial direction; and a housing accommodating the rotor main body, the rotor fan, and the armature therein. The bearing mechanism includes a first bearing above the rotor fan in the housing and facing the rotor fan in the up and down direction and a second bearing positioned below the rotor main body. The housing includes a first opening, a second opening, and a bearing holding portion.
