PURPOSE: A device for self-injecting air of a wheel for an automobile is provided to always keep most suitable inner pressure of a wheel as inflowing outer air to the inside of the tire automatically by rotary force occurred when an automobile drives. CONSTITUTION: A device for self-injecting air of a wheel consists of a compressed apparatus pressed outer air as rotating together according to rotation of constant joint(1) transferred rotary force of an engine; an inlet apparatus inletting compressed air inside of a wheel(W) through the compressed apparatus; a control apparatus intercepting inflow of air if the inner pressure of the wheel rises over the fixed pressure. The compressed apparatus consists of a knuckle(4) forming circular outer chamber(4a), and an impeller forming an inner chamber(5a) inletting compressed pressure to the inside of the wheel, a pair of blades(6) controlling the length. The inlet apparatus consists of a constant joint forming an air passage(1a) located in the inner chamber of the impeller and a rim(3) forming an air passage(3a) inletting air to the inside of the wheel. The control apparatus consists of an inlet passage inletting the compressed air by shrinkage of the blades, a feed passage inletting a moving plate moved by the air pressure from the inlet passage to the inner chamber of the impeller, and a breaking passage opened to the outer chamber of the knuckle as connecting to an extended chamber. The impeller is rotated inside of the outer chamber of the knuckle with the constant joint and rotates the blades if an automobile drives. By the pressure according to contact with an end part of the blade and the wall face of an eccentric part of the outer chamber, a supporting flange put in the extended chamber is moved as pressing a spring and the end part of the blade inlets the compressed air as opening the inlet passage. Pressed air inlets to the inlet passage and opens the feed passage as moving the moving plate. By connecting the inlet passage and the feed passage, the pressed air is filled to the inner chamber of the impeller, and keeps the inner pressure of the wheel optimally as inletting to the wheel through the air passages of the constant joint and the rim.
