PROBLEM TO BE SOLVED: To provide a plastic flow resistance damper device in which the temperature of the plastic flow body is restricted to rise in motion of vibration control. SOLUTION: The plastic flow resistance damper device has a cylinder 1, a piston rod 2 penetrating the cylinder 1 in the axis line direction, a plurality of pistons 4A, 4B, 4C secured to the piston rod 2, a plastic flow body 6 filled in the cylinder 1, and a choke side 3 communicating with a side chamber 5A of the piston 4 and the other side chamber 5B, and with which the plastic flow body 6 can communicate. The size of the choke part 3 (interval) is made greater than the case when only one piston is provided.
