PROBLEM TO BE SOLVED: To provide an air suspension type seat support device for a vehicle which can downsize a cam for opening/closing a valve of an air spring according to an increase of a seat height adjustment amount and suppressing an interference with a peripheral member of the cam.SOLUTION: An operating angle of a first cam 55 is held by a stopper means to keep an opening state or a closing state of a valve 70, and an operating angle of the first cam 55 is also held to keep the opening state or closing state of the valve 70 even when the valve 70 relatively moves in a longitudinal direction with respect to a height position transmission pin 56 and the first cam 55 deviates from the height position transmission pin 56. A part to be brought into contact with the height position transmission pin 56 in the first cam 55 is only required to be so long as to rotate to the operating angle, so that the first cam 55 can be downsized. |
