Title:
流体ダンパ装置およびダンパ付き機器
Document Type and Number:
Japanese Patent JP6396689
Kind Code:
B2
Abstract:
Provided is a fluid damper device with which it is possible to suppress lifting of a valve body from a turning shaft when a rotor is rotated in the direction of opening. Also provided is an apparatus with this fluid damper device. Specifically, in a damper chamber (11) of this fluid damper device (10), a protruded part (52) of a valve body (50) protrudes from a base part (51) toward the outside in the radial direction of a turning shaft (40), and toward one side (a first direction (A)) around the axial line (L) of the turning shaft (40), and a valve body support part (460) of the turning shaft (40) is equipped with a base part support part (463) between a first protruded part (461) and a second protruded part (462). An inner side portion (520) of the protruded part (52) of the valve body (50) has a first portion (521) and a second portion (522) separated from each other in the direction in which the protruded part (52) protrudes, and when the valve body is in the open position this first portion and second portion are supported by a receiving part (466) formed on the first protruded part (461) of the turning shaft (40). Therefore, even when the valve body (50) is subjected to fluid pressure in the first direction (A), a situation in which the valve body (50) rotates with the point of contact with the first protruded part (461) as a fulcrum does not easily occur.
