PURPOSE: A rubber cone with an alarm function is provided to enable a worker to rapidly escape from risk since whistle rings due to the opening of a valve when external shock is applied. CONSTITUTION: A rubber cone with an alarm function comprises a support(20), an alarm unit and a sensor(40). The support is integrally or detachably coupled to the lower end of a cone(10) and comprises an air tank, which stores air pressure. The alarm unit connects an air tank to a pipe and a whistle generator(36) and comprises an opening/closing valve on the pipe. The sensor generates the operating force of the opening/closing valve in cooperation with the conduction of the cone.
