It is an object of the present invention to provide a technique capable of making a knee joint of an artificial leg close to a movement of a knee of a human body with a simple configuration. The knee joint component, which is one application example of the present invention, includes a first oil passageconnecting a first oil chamberand a second oil chamberin a cylinder tubecoupled to a socketmounted on a thigh part, a second oil passagebranched from the first oil passageso as to be in parallel with the first oil passage, and a switching mechanismthat switches whether a oilpasses through the first oil passageor the second oil passage, which are different from the first oil passagein the passage characteristics, and the switching mechanismthat is rotatably mounted around the first rotating shaftand that is rotatable by its own weight when the artificial legis tilted, and a first rotating memberthat switches whether the oilpasses through the first oil passageor the second oil passageby opening or closing the inlet/outletof the second oil passage
