  • Holding Or Fastening Of Disk On Rotational Shaft (AREA)

Abstract

PURPOSE:To enable the clamping of the true center of a disk to be performed, by forming three aligning projections in the periphery of the center of a housing space to house the shaft end part of a spindle shaft at equal intervals, and forming a lug projection at the lower end part of the inner periphery of each aligning projection. CONSTITUTION:A boss part 12 is formed in the center part of a clamper 10, and a recessed part is formed at the lower part of the boss part 12 confronting with the disk D, and the three aligning projections 15 are arranged protrusively within the recessed part and also on a virtual circle at the center position of the clamper 10, and the lug projections 15A are formed on the inner peripheral planes of the lower end parts of the aligning projections 15, which permits contact with a spindle 2 at a small contact area. In such a way, the clamper 10 can be introduced to the shaft center of the spindle 2 by a sensitive function for the shaft end of the spindle 2, thereby, the center part of the disk D can be clamped exactly.
