The present invention provides a load control function capable of controlling the fluid pressure adjusted for the generation of a load of a hydraulic cylinder applied to sporting equipment or the like at long range by a simple mechanical operation and easily compensating for the fluid loss due to a long-term use. The object of the present invention is achieved by an apparatus to control the pressure of a hydraulic cylinder which is assembled in a head cover of one side of the hydraulic cylinder generating a load and controls the flow of the internal fluid pressure. The apparatus for controlling the pressure of a hydraulic cylinder comprises: a hydraulic flow interruption means installed to open and close a duct of a connection flow path interconnected with a cylinder chamber of the hydraulic cylinder from the head cover; a hydraulic extension line unit of a flexible hydraulic hose whereof one side is assembled in an airtight state and extended to the hydraulic flow interruption means; and a hydraulic control input means assembled to an end portion of the flexible hydraulic hose of the hydraulic extension line unit in an airtight state, gradually adjusting the fluid pressure filled inside, and controlling the opening and closing operation of the hydraulic flow interruption means. |
