Patent ID: 8807967

Claim:
A blower fan, comprising: a shaft; a rotor magnet arranged to rotate about a rotation axis together with the shaft; a stator arranged radially outwards of the rotor magnet in an opposing relationship with the rotor magnet; a substantially cylindrical holder unit arranged to rotatably support the shaft through a bearing, an inner surface of the holder unit directly contacting the stator along an entire axial extent of the stator; an impeller arranged to rotate together with the shaft; and a housing arranged to surround the impeller and the holder unit; wherein the bearing includes a pair of axially spaced-apart bearing units, the rotor magnet and the stator are arranged axially between the bearing units, and the bearing units and the stator being held on an inner circumferential surface of the holder unit; the housing is directly connected to the holder unit through a plurality of connecting members, at least one of the plurality of connecting members overlapping one of the pair of axially spaced-apart bearing units in a radial direction; and a radially outermost portion of at least one of the bearing units contacts the substantially cylindrical holder unit at a position which is radially outward from a radially outermost portion of the stator.
