The hydraulic jack is a well-known one.For example, when a worker performs an operation such as depressing a pedal, a predetermined hydraulic mechanism is operated, and a hydraulic jack that allows the jack tip to freely move up and down to a predetermined height is provided. use.

On the other hand, the intersecting link members 8a and 8b are composed of a link member 8a having a telescopic angle adjusting mechanism 9 at one end thereof and a link member 8b having a fixed length. It is pivoted on. A fixed ring 11a is provided at an end of the link member 8a on the base 3 side, and the fixed ring 11a is rotatably supported on the upper surface of the base 3 while the angle of the end of the link member 8a on the base 4 side is set. The adjusting mechanism 9 is provided with a moving wheel 12a. The moving wheel 12a is located in a channel-shaped groove of the guide member 4a on the pedestal 4 side, and its movement is restricted to only one direction. A fixed wheel 11b is provided at an end of the link member 8b on the pedestal 4 side,
