PROBLEM TO BE SOLVED: To provide a pneumatic elevator which is satisfactory in comfortableness and does not impose a large burden on a blower. SOLUTION: A pneumatic elevator 3 elevating/lowering a gondola 31 by being provided with a bellows 32 which is provided at the lower part of the gondola 31 and is freely extensible in the vertical direction, a blower 33 putting and exhausting air into/from this bellows 32 and a piping 34 connecting this blower 33 and the bellows 32 and elongating and contracting the bellows 32 in the vertical direction by the blower 33 is provided with a control valve 36 regulating blowing amount from the blower 33 to the bellows 32 and a pressure regulating means 37 regulating pneumatics within the bellows 32, regardless of the opening and closing operations of this control valve 36, on the middle of the piping 34. Because the pneumatic elevator 3 is provided with the control valve 36, the speed of the gondola 31 can be gradually increased/decreased by regulating the control valve 36. |
