PROBLEM TO BE SOLVED: To prevent the occurrence of a second accident or the accidental damage from spreading at the time of derailment. SOLUTION: A yaw damper device for a railway rolling stock is equipped with a yaw damper 20 which is provided at the end part of at least either right or left between a railway rolling stock 100 and the railway rolling stock 100 coupled in the longitudinal direction, and applies a resistance force for moving in the contact/separation direction of each vehicle by a viscosity resistance in moving of the interior oil, and derailment detection means 11L, 11R detecting the derailment state of either one of the railway rolling stocks. Respective dampers are provided with regulation means 26, 28, 30, 32 capable of switching a movable state of the interior oil and a moving regulation state, and a control means 40 which performs the control for switching the regulation means of respective yaw damper from a fluid state to the moving regulation state when the derailment state is detected by the derailment detection means.
