A motor includes a bearing portion, a chassis, a thrust pad and a plurality of supporting members. The bearing portion is formed of a sintered oilless bearing or the like and supports a rotary shaft of the bearing portion. The chassis has a stator attached thereto and has a cylindrical holding portion for retaining therein the bearing portion integrally formed therewith. The thrust pad is disposed within the holding portion and pivotally supports the rotary shaft in the thrust direction. The supporting members are disposed on the bottom surface portion of the holding portion and support the thrust pad.

DETAILED DESCRIPTION It is therefore an object of the present invention to provide a motor in which the above-mentioned problems can be solved.
According to the present invention, there is provided a motor which includes a bearing portion, a chassis, a thrust pad and a plurality of supporting members.
The bearing portion supports a rotary shaft of a rotor.
A holding portion for retaining therein the bearing portion is integrally formed with the chassis.
The thrust pad is disposed within the holding portion to pivotally support the rotary shaft in the thrust direction.
The supporting members support the thrust pad provided on the bottom portion of the holding portion.
According to the present invention, there is provided a motor which includes a bearing portion, a chassis and a magnet.
The bearing portion supports a rotary shaft of a rotor.
A holding portion for retaining therein the bearing portion is integrally formed with the chassis.
The magnet is attached to the rotor to directly apply an attraction between it and the chassis.
