Title:
MAGNETIC VISCOSITY FLUID DEVICE
Document Type and Number:
Japanese Patent JP2023061173
Kind Code:
A
Abstract:
To provide a magnetic viscosity fluid device which can form a magnetic path efficiently by reducing magnetic resistance of a yoke.SOLUTION: A magnetic viscosity fluid device 1 includes: a rotary plate 20; a first yoke 30 which faces the rotary plate through a first gap S1; a second yoke 40 which faces the rotary plate through a second gap S2; a magnetic viscous fluid 50 disposed between the first gap and the second gap; and a coil 60. The first yoke and the second yoke have a magnetic flux delivery part 70. The first yoke has: a first yoke base part 31 around which the coil is arranged; and a first yoke first extending part 32. The second yoke 40 has: a second yoke base part 41 disposed at a major surface 22 side of the rotary plate; and a second yoke extending part 42 which forms the magnetic flux delivery part with the first yoke first extending part while extending from the second yoke base part. The first yoke base part and the first yoke first extending part are integrally formed without a parting surface being disposed therebetween.SELECTED DRAWING: Figure 1
