PROBLEM TO BE SOLVED: To easily mount/demount a heater, and to improve maintenance performance by forming an electric heater in a gear shape, horizontally inserting the bar-shaped heater into the bottom part of a pressure chamber through a connector part arranged in a case, and thread-mounting the tail end part of the bar-shaped heater on the connector part. SOLUTION: A pressure chamber is defined between a case 12 and a damper body of an inverted damper having the damper body and a damper rod so that a pressure medium is sealed in the pressure chamber. A bar-shaped electric heater 16 positioned on the car width directional inside to the damper rod and a temperature sensor 17 positioned on the car width directional outside to the damper rod are arranged in the bottom part of the pressure chamber. In this case, the bar-shaped electric heater 16 is horizontally inserted into the pressure chamber through a connector part 12c arranged in the case 12, and the tail end part of the bar-shaped electric heater 16 is thread-mounted on the connector part 12c. The temperature sensor 17 is also horizontally inserted into the pressure chamber through a connector part 12d arranged in the case 12, and the tail end part is thread-mounted on the connector part 12d.
