るデイスク位置決め機構。 In a floppy disk drive device that uses a 3.5-inch floppy disk, a spring holding plate and a spring plate spaced apart from the spring holding plate at a predetermined distance are attached to a spindle shaft rotated by a drive source, and A drive pin that engages with the drive hole of the disk hub is provided upright on the opposite side of the spring holding plate, and in order to prevent the drive pin that contacts the corner of the drive hole from moving in the direction opposite to the direction of rotation. A disk positioning mechanism for a floppy disk drive device, characterized in that a bent piece is formed by bending a part of the spring plate toward the spring holding plate on the rear side of the drive pin in the direction of rotation.
