PURPOSE: A device for removing rainwater from a side mirror is provided to enable a driver to secure visual field in a rainy day by detecting rainwater on a mirror surface and moving a blade on the mirror surface. CONSTITUTION: A plurality of humidity sensors(10) are installed at a mirror surface(100), and detect rainwater on the mirror surface. A controller(20) receives signals from the humidity sensors, and outputs a control signal for driving a motor(30). A motor driving unit(25) receives the control signal. A plate spring(40) is wound around a motor shaft, and protrudes into the top of the mirror along a guide groove. A blade(45) is coupled to the end of the plate spring, and is in contact with the mirror surface.
