PURPOSE:To reduce the consumption quantity of air and to control generation of a sound at the time of kneeling, by providing a kneeling valve in an air supply duct corresponding to one side bellows. CONSTITUTION:When a kneeling switch 30 is closed, air in the inside of belllows 16 is streamed in a kneeling tank 24 from a discharge opening 20a opened at this time through a kneeling valve 20 by closing the kneeling valve 20 and a cut valve 22. As all of the air in the inside of the bellows 16 is not discharged always and a part of the same is remained within the bellows, the title device can be done with a little consumption quantity of the air. As a solenoid valve 38 is closed when a switch 30 is opened, the kneeling valve 20 and a cut valve 32 are opened and air is supplied to the bellows from an air tank 12 until the car reaches to a predetermined car height value established by a levelling valve 22. |
