Document Type and Number:
Japanese Patent JP6571551
Kind Code:
B2
Abstract:
Provided are: a fluid damper device with which leakage of a fluid between the bottom wall of a case and a rotor can be effectively suppressed when the rotor is rotated in a direction in which a load is generated; and an apparatus with a damper, said apparatus being provided with the fluid damper device. Specifically, this fluid damper device 10 has a cylindrical case 20, which is provided with a bottom wall, and a rotor 30, which has a valve 50 supported on the outer peripheral side of a rotating shaft 40, wherein a fluid 12 is filled into a damper chamber 11 that is demarcated by the case 20 and the rotor 30. The rotor has a first rib 58 on a first end surface 57 that is the end surface of the valve 50 facing the bottom wall, and the first rib 58 is provided with a valve-side first extension portion 581 that extends in a radial direction. Consequently, the space between the bottom wall of the case 20 and the valve 50 in the direction of the central axis L of the rotating shaft 40 can be sufficiently filled.
