A spindle motor can include a rotor support piece, which may rotatably support a rotor that is inserted onto one end, and which may include a projecting part that protrudes from the other end and a mounting part that has a flat surface formed along the periphery of the projecting part; a base plate, in which an insertion hole may be formed for inserting the projecting part through, and on which multiple support protrusions may be formed along the periphery of the insertion hole for supporting the mounting part along a periphery of the insertion hole; and a buffer member, which may include a projecting-part hole for inserting the projecting part through and support-protrusion holes for inserting the support protrusions through, and which may be positioned between the rotor support piece and the base plate to absorb vibration. This arrangement can reduce the occurrence and transfer of vibrations. |
