A sun-visor is provided to form a space between a door and a seat of a vehicle by operating a switch installed on a door of a vehicle to supply power to a driving shaft such that rain protectors are spread. A sun-visor(12) comprises rain protectors(11) having a driving shaft(10) and a control box. The rain protector forms a shelter space for protecting an occupant from rain in getting on/off the vehicle. A length of the rain protectors is controlled to prevent rain from penetrating into the vehicle when driving the vehicle. The rain protector is opened or closed when a switch(13) installed at a lower end of the vehicle is pressed. When getting on/off the vehicle, the switch is pressed to open the rain protector. After getting on/off the vehicle, the switch is again pressed to close the rain protector. The rain protector provides the space in which the occupant opens/closes an umbrella.
