PROBLEM TO BE SOLVED: To provide an MR fluid damper capable of reducing amount of use of MR fluid and simplifying a magnetic field generating device. SOLUTION: This MR fluid damper 10 is constituted by inserting a piston rod 12 into a damper tube 11, providing a first piston 20 and a second piston 30 sliding in the damper tube 11 at two positions in the axial direction of a piston rod 12, and partitioning an MR fluid storage chamber 13 nipped by the first and second pistons 20, 30 of the piston rod 12 to store MR fluid inside the damper tube 11. The magnetic field generating device 40 is provided in a part facing the MR fluid storage chamber 13 of the damper tube 11, the magnetic field generating device 40 partitions the MR fluid storage chamber 13 into two upper and lower chambers 13A, 13B, and a flow passage 14 for MR fluid communicating two upper and lower chambers between the piston rod 12 and it is formed.
