PROBLEM TO BE SOLVED: To provide a leveling valve operation device which can prevent the mis-operation of the leveling valve by varying the connection position of a car height rod with a car height lever of the leveling valve responsing to the car height displacement by a road surface state and also improve the responsiveness of an air spring against the road surface state. SOLUTION: A leveling valve operation device is constituted between a leveling valve for supplying an operation air to an air spring intermittently responding to the operation of a rotary plate and the suspension of a wheel side, and is constituted by a car height lever whose oneside is connected with the rotary plate of the leveling valve and the outside of a valve body and on whose other side a connection hole, on whose one surface a rack is engraved, is bored along a longitudinal direction, a car height rod whose one end is mounted through a ball joint to oneside of the suspension and whose outer shape is a semi-circular shape and on whose center part a semi-circular slot is engaraved and a variable connection device mounted through the connection hole of the car height lever and the slot of the car height rod and which can vary the connection position of the car height lever with the car height rod responding to the road surface state. |
