Bearing device and motor mounted with the bearing device

A motor comprising:

• a shaft;
• a stator including a sleeve for supporting the shaft so as to be rotatable freely and a housing having a through hole into which the sleeve is inserted;
• and
• a rotor having a hub to be fixed to the shaft being supported through the shaft so as to be rotatable freely with respect to the stator,
• wherein a circumferential groove extending in a circumferential direction is formed on either one surface of an outer circumferential surface of the sleeve and an inner circumferential surface of the housing that confronts with the outer circumferential surface of the sleeve, and
• wherein an axial groove that extends approximately in parallel to a central axis of the sleeve is formed on either one surface of the outer circumferential surface of the sleeve and the inner circumferential surface of the housing, and, and
• further wherein the outer circumferential surface of the sleeve is glued to the inner circumferential surface of the housing by adhesive that intervenes in both the circumferential groove and the axial groove.
