VISCOUS FLUID-SEALED DAMPER AND VIBRATION CONTROL SUPPORT DEICE OF DISK PLAYER USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a viscous fluid-sealed damper easy in installation to a mechanical deck, and without reducing a damping characteristic thereby, when backlash is caused when an installation shaft part integrally molded in an agitating part is abraded, even when violent vibration is repeatedly applied.;SOLUTION: This viscous fluid-sealed damper 22 integral with an installation shaft part 34 is provided for absorbing vibration based on the agitating action to a viscous fluid L of an agitating part 32, by sealing the viscous fluid L inside in a sealed vessel shape. The installation shaft part 34 comprises a core part 44 of a hard resin central part integrally molded in the agitating part 32 in a state of being buried in a burying hole 46 of the agitating part 32, and a soft covering part 57 arranged in a state of being fixed to an outer surface of the core part 44 in an installation part 50 to the mechanical deck, interposed between the core part 44 and the mechanical deck and elastically contacting with the mechanical deck in a close contact state.;COPYRIGHT: (C)2010,JPO&INPIT
