PROBLEM TO BE SOLVED: To adjust the seat height by reliably opening/closing a valve even when the seat height is low in an air suspension type seat support device for a vehicle.SOLUTION: When a position transmitting pin 56 is longitudinally moved as an air suspension 1 is expanded/contracted, a first cam 55 is rotated, a second cam 59 is pressed by a cam part 55d of the first cam 55 and inverted to push valve stems 72A, 73A of a valve 70, and the valve 70 is opened/closed accordingly. The movement of the second cam 59 is amplified compared with the movement of the position transmitting pin 56 by the first cam 55, and the valve opening/closing motion is increased to reliably open/close the valve 70. |
