A rigidity variable strut bar is provided to block or unblock oil flow according to a signal by placing an electromagnet inside a strut bar so as to adjust the rigidity of the strut bar based on the state of a vehicle. A rigidity variable strut bar(100) includes a rigid joint and a bush connecting part. The rigid joint is fixed to one side of a car body. One end of the bush connecting part is combined with the other side of the car body. Oil is filled in the strut bar and the length of the strut bar is reduced or extended according to flow of the oil. The strut bar includes an electromagnet(130) and a magnet(140). The electromagnet is activated when power is applied to the strut bar. The magnet forms a flow path(150) through which the oil flows when power is applied to the strut bar. |
