置。[Claims for Utility Model Registration] (1) A motor that is rotatably driven on a hub stand that is fixed to the end of the rotating shaft of an electric motor and rotates with the rotating shaft, has a rotating shaft insertion hole in the center, and has a drive pin inserted at an eccentric position. A drive pin that engages with the drive pin insertion hole of the disk having a hole is implanted in an elastic member that can be elastically deflected in the axial direction of the rotating shaft so as to be able to move in and out of the disk mounting surface of the hub stand. In addition, the hub stand is provided with a stopper that regulates the displacement of the elastic member in the pin retraction direction and prevents the drive pin from completely retracting from the disk mounting surface of the hub stand. Device. (2) The disk drive device according to claim 1, wherein the shape of the stopper substantially corresponds to the displacement curve of the elastic member. (3) The disk drive device according to claim 1, wherein the stopper is made of an elastic material having a spring constant greater than that of the elastic member.
