PURPOSE: A road stud with an alarm function is provided to enable a driver to rapidly and accurately recognize the state of a vehicle which is separated from a lane. CONSTITUTION: A road stud with an alarm function comprises main body(110), a pumping unit(120), a fixing member(130), a second check valve(140), a nozzle(150), an air tube, a self-power generation unit, and an alarm. The main body has a reflector(114), a hollow(117), and a first check valve(119). The pumping unit generates compressed air. The fixing member fixes the pumping unit. The second check valve prevents the generated compressed air from backward flowing. The nozzle is installed in the fixing unit. The air tube is connected to the nozzle and guides the compressed air. The self-power generation unit generates electricity by rotating a wing part using the compressed air transferred from the air tube and operates a display unit. The alarm is installed in the wing part and converts the compressed air into amplified sound energy.
