Abstract
There is provided a motor formed to have a simple coupling structure between a base plate and a sleeve holder, thereby implementing a simple structure and reducing costs and processes taken for manufacturing the motor, and an optical disc drive using the same. To this end, the motor includes a base plate having at least one protrusion formed therein, and a sleeve holder having a body part, of which the shape is cylindrical and in which a sleeve is fitted, and a flange protrudingly formed from a lower end of the body part in such a manner as to make surface-to-surface contact with an upper surface of the base plate, wherein the flange is formed to have at least one insertion hole, through which the protrusion is inserted so that the sleeve holder is coupled to the base plate.
