A disk-shaped magnetic attraction plate made of a ferromagnetic material fixed to the output shaft of a spindle mechanism, and a drive pin protruding from a window hole provided near the outer periphery of the magnetic attraction plate. A swing arm fixed to the window hole so as to be movable in the radial direction and vertical direction, and a magnetic disk that inserts and attaches the magnetic disk to the rotation center of the spindle output shaft by a force applied to the swing arm in the outer circumferential direction of the magnetic adsorption plate. 1. A magnetic disk mounting mechanism, characterized in that the magnetic adsorption plate, the central axis of rotation of the swing arm, and a holding member for holding the swing arm are integrally resin molded from the same material. 2. The central axis of rotation of the swing arm is a cylindrical projection that engages in a hole provided near the base of the swing arm with respect to the drive pin installed on the back surface of the magnetic adsorption plate, and the holding member 2. The magnetic disk mounting mechanism according to claim 1, wherein the cross-sectional shape is protruded in a U-shape so as to be able to engage and hold the base portion of the swing arm.
