PURPOSE: A horizontal rotating jack is provided to improve spatial utilization of the rear part of a vehicle body by not projecting a horizontal jack to the top of the vehicle body. CONSTITUTION: A horizontal rotating jack comprises an upper cylinder(10), a lower cylinder(20), a footrest member(30), a connection part(12), a fixation pin(18), a fixing unit(40), an eccentric unit(46), and a rotation rod(22). The lower cylinder is expanded and contracted on the inner diameter of the upper cylinder. The connection part is integrated with the upper end of the upper cylinder and is formed with a hole(14). The fixation pin fixes the connection part to the vehicle body and functions as a rotation hinge point. The fixing unit engages with the groove and fixes the upper cylinder to the vehicle body. The rotation rod is parallelly expended to the upper and lower cylinders. |
