Title:
ROTATIONAL VISCOUS DAMPER
Document Type and Number:
Japanese Patent JPH07301271
Kind Code:
A
Abstract:
PURPOSE: To damp only the rotation of a specified tuning angle part in a turning shaft less than other tuning angle parts.
CONSTITUTION: A rotational viscous damper is so constituted that a turning shaft 4 with an eccentric body 3 is installed in a vessel 1 where a magnetic fluid 2 is built in, and this magnetic fluid 2 is partially magnetized from the outside of the vessel 1, whereby only the rotation of a specified tuning angle part in the tuning shaft 4 can be damped. Therefore a good damping effect of the turning shaft in the rotational direction is securable.
