PURPOSE: A hydraulic jack is provided to prevent the durability of components and to conveniently transfer the components by changing the material of the components. CONSTITUTION: A handle lever(22) is rotated clockwise and counterclockwise and up and down by centering on a hinge(23) and a piston in a cylinder(24) reciprocates. The fluid flowing into the cylinder from exterior is compressed and the compressed fluid flows into a fluid and air inlet(11) formed in the lower of a body(1) via a connecting pipe(25). An elevating member(3) ascends while sliding on the body. According to the elevation of the elevating member, a spring(2) is extended until the elevating member ascends to a maximum height, when a sill(31) of the elevating member is hung on a hanging unit(6). |
