Abstract: A leveling valve includes: a seat portion configured to define a flow passage, the flow passage communicating with the air cushion and a compressed air source or communicating with the air cushion and a drain; a valve configured to move in an axial direction in accordance with a relative displacement of the vehicle body with respect to the truck; a spring configured to bias the valve toward a closing side, the valve being in contact with the seat portion in the closing side; a valve guide configured to support one end of the spring, the valve guide being slidably inserted with respect to a housing inner wall surface; and a communication port opened to the housing inner wall surface. A moving region in which the valve guide moves is set to a position offset from the communication port in the axial direction.
