A rotary force control apparatus capable of being used widely in an automobile, an airplane, a ship and a general industrial machinery. The rotary force control apparatus of the present invention can be used in an apparatus for performing an open- and-shut action while rotating with a center of a hinge, such as a shock- absorber, an engine room cover or a cover for a cargo loading room used for a shock absorption in the machinery for the transport such as an automobile, an airplane or a ship, and can also be used in a door built in a general building. The present invention is provided for controlling a rotation speed according to the pressure of the oil filled in a housing. Also, as in a door, or in the engine room cover of the automobile or the airplane, the present invention has a structure which be efficiently applied to both a case of making the speed with which the door or cover is opened differed from the speed with which the door or cover is closed, and a case c>f making the speed with which the door or cover is opened and the speed with which the door or cover is closed same. The present invention has a very simple configuration, which facilitates a manufacture process. Also, in accordance with the present invention, which makes a rotary force controlled by the oil pressure and makes the rotary force controlled according to the traveling amount of the oil, a very soft operation is assured and a noise generation is reduced significantly.
