PURPOSE: A spindle motor is provided to increase binding power with a base member through a protrusion unit which is combined with an insertion hole of the base member, thereby reducing separation of a pulling plate from the base member caused by external shock. CONSTITUTION: A stator includes a base member(120). A pulling plate(140) is mounted on the base member. A driving magnet(180) is installed in a rotor hub. The pulling plate includes a circular hook shape body(142), an extension unit(144), and a protrusion unit(146). The extension unit is extended from an edge of the body to an upper unit of an axis direction. The protrusion unit is extended from a lower side of the body to a lower unit of the axis direction.
