Title:
FLUID DAMPER DEVICE AND DEVICE WITH DAMPER
Document Type and Number:
Japanese Patent JP2016001005
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fluid damper device capable of smoothly shifting an attitude of a valve element to a closed attitude when a rotary shaft is rotated in a closing direction, and a damper-added device with the fluid damper device.SOLUTION: In a fluid damper device, a protruding portion 52 of a valve element 50 protrudes from a base 51 radially outward of a rotary shaft 40 and to one side (first direction A) about an axis L of the rotary shaft 40 while a valve support 460 of the rotary shaft 40 includes a base support portion 463 between a first convex portion 461 and a second convex portion 462. A radially outward end portion 465 of the first convex portion 461 includes an inclined surface 464 inclined with respect to an inner part 520 of the valve element 50, and the inclined surface 464 enables a distance between the inner part 520 of the valve element 50 and the end portion 465 (inclined surface 464) of the first convex portion 461 to increase from a second direction B to a first direction A.
