ABSTRACT:
A turn table of a motor includes a first cylindrical portion extending in an axial direction, a first discoid portion radially outwardly extending from the first cylindrical portion, and a second discoid portion radially outwardly extending from the second cylindrical portion. A chucking member arranged on the turn table includes a main body having a diameter substantially the same as that of a center opening of a data storage disk to be arranged on the motor. The chucking member also includes a plurality of chucking claws having radially tip ends arranged radially outside of the outer circumferential surface of the main body and a plurality of coil springs applying bias force pressing the chucking claws in the radially outer direction. A radially inner end of each of the coil springs comes in contact with and is supported by at least one of the radially inner wall of the main body and the second cylindrical portion of the turn table.
