There is provided a gas-pressure type gravity compensation elevator for ascending/descending a load object, which includes a control part. The control part is adapted to selectively connect a constant-pressure gas cylinder maintained at a constant pressure according to the grasping state, to a gas cylinder for exerting a driving force in the direction of ascent on an elevating mechanism. Further, the control part is adapted to control a sum of a volumes in the gas cylinder and the constant-pressure gas cylinder such that it equals to a sum of their average volumes, every time the grasping state is changed.
