Abstract
PURPOSE: To perform an automobile jacking operation from a safe place by supplying gas from a liquefied gas container into the inner sealed space of an expandable and contractible jack by means of a tube of an appropriate length which can be bent freely. CONSTITUTION: A jack main body comprises a movable cylinder 2 and a fixed cylinder 1 and is covered with a bellows 3. The fixed cylinder 1 is in the form of a bottomed cylinder having a flange at its bottom, and a liquefied gas can 8 and a tube 7 are enclosed in the internal empty chamber (c) thereof. During actuation, the liquefied gas can 8 and the tube 7 are taken out, and the gas can 8 placed in an appropriate place and the tube 7 connected to the upper flange of the fixed cylinder 1 by a joint are drawn out. Then a valve 11 is opened and saturated vapor is supplied into a sealed air chamber (a) formed by the fixed cylinder 1 and the movable cylinder 2 to effect jacking-up. Therefore, the valve can be operated in a safe place remote from the jack main body, and tire replacement becomes safe and easy.
