To provide a damper device between railroad cars, capable of reducing rolling vibration of car bodies and suppressing adverse effects to riding comfort in a vertical direction.

The damper device between railroad cars has a damper 30 which is provided between first and second cars 10, 20 and generates an attenuation force depending on a relative rolling speed between car bodies 11, 12. In the damper device, the damper 30 includes a minute vibration buffering mechanism 100 having a first member 35 provided on first and second attenuation force generating mechanisms 33, 34, a second member 120 capable of relatively moving to the second member upon reception of the attenuation force transmitted from the first member, elastic members 140, 150 provided between the first and second members, and stoppers 170, 180 for regulating the relative displacement between the first and second members.
