The present invention relates to a hydraulic jockey, and more particularly, to a hydraulic jockey capable of supporting two planes arranged orthogonally to one another. The jockey of the present invention comprises a housing, piston means, and shaft means. The piston means is capable of reciprocating along a straight line within the housing. The shaft means includes a first shaft unit and a second shaft unit which support two planes arranged orthogonally to one another. One end of the first shaft unit supports any one of the two planes arranged orthogonally to one another. One end of the second shaft supports any one of the two planes arranged orthogonally to one another. When the piston means reciprocates, one end of the first shaft unit and one end of the second shaft unit are spaced apart from each other and are brought closer to one another along another straight line arranged vertically to said straight line. The present invention provides a hydraulic jockey which supports planes of a member arranged orthogonally to one another, and moves the member, thereby eliminating the necessity of welding a separate fixing plate and grinding the resulting structure. Thus, unnecessary processes are eliminated to reduce manpower costs, material costs, etc. |
