PROBLEM TO BE SOLVED: To prevent an adhesive from falling on a fitting portion of a bearing, by receiving excessive adhesive that falls into an annular groove formed on the circumferential surface of a hollow shaft. SOLUTION: In this hollow shaft rotor structure, the annular groove (10) and the bearing-fitting portion (4) are formed at the positions near magnets (3) on the circumferential surface (2) of the hollow shaft (1). It is configured to receive the excessive adhesive in the groove (10) so as to prevent the adhesive from reaching the bearing-fitting portion (4). COPYRIGHT: (C)2005,JPO&NCIPI
