Title: Disk device
Inventor: KATO KAZUNARI
IPC: G11B17/022
Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To solve the problem that large force partially acts to a clamping member holding a clamper and also large force to lift up the clamping member is needed since the conventional on-vehicle disk device uses a spring to exert strong elastic force as spring to provide clamping force needed for clamping a disk to the clamper. SOLUTION: The clamping member 13 holding the clamper 18 is pressed to a supporting part 20a by a holding elastic member 26 and a clamping elastic member 27 is hung between a drive chassis 20 and the clamping member 13 at the other side. A distance Lb from a supporting fulcrum 51 to an operating part 52 of the elastic force of the clamping elastic member 27 is longer than a distance La from the supporting fulcrum 51 to an operating part 53 of clamping force Fx, and therefore the elastic force F2 of the clamping elastic member 27 to set the clamping force Fx does not need the large force. Thereby the large force from the clamping elastic member 27 does not partially exert to the clamping member 13.
