Document Type and Number:
Japanese Patent JP7082910
Kind Code:
B2
Abstract:
To provide a magneto rheological fluid device which can inhibit pressure rise effectively.SOLUTION: A magneto rheological fluid device includes: a case 2 in which a magnetic viscous fluid is enclosed; a disc 3 in which at least a part thereof is formed by a magnetic substance and which is disposed in the case 2 and rotates while contacting with the magnetic viscous fluid; a rotary shaft 4 fixed to a radial center of the disc 3; and a magnetic field generation part 5 which generates magnetic fields so that a magnetic path passes through the magnetic viscous fluid and the disc 3. A gas is mixed to the magnetic viscous fluid and the magneto rheological fluid device includes a storage part 220 for releasing a part of the magnetic viscous fluid when pressure increases in the case 2.SELECTED DRAWING: Figure 2
