摘要： In a motor including a chucking device for detachably holding a disk, the chucking device has a center case to which a central opening of the disk is inserted; resilient members received within the center case; and claw members for holding the disk in place. Each of the claw members has a tip end portion, a disk holding surface positioned axially below the tip end portion for holding the disk in place, and a recessed sliding portion formed substantially at a circumferential center region of the disk holding surface, the sliding portion serving to guide movement of the claw member. Rest portions are formed in the center case in a facing relationship with the respective sliding portions, the rest portions serving to support the respective sliding portions by contacting therewith. Each of the rest portions has an upwardly convex curved surface with which the corresponding sliding portion makes contact.

摘要： A claw member includes at a radially inward surface thereof a protrusion inclined surface in order to minimize deformation occurring in an axial direction to an elastic member which is a coil spring. The protrusion inclined surface is preferably inclined, when a tip portion of the claw member is at an axially lowest point, to be substantially perpendicular to the central axis, or such that the further radially inward a portion thereof is the axially lower the portion is. By virtue of such configuration, the protrusion inclined surface minimizes deformation occurring to the elastic member in the axial direction.
