PURPOSE: An outdoor shading device is provided to prevent indoor temperature from being increased by installing a shading unit outside a window and to minimize the influences of wind. CONSTITUTION: An outdoor shading device comprises guide bars(100), shading units(200), a main drive unit(300), and an angle regulation unit(400). The guide bars are arranged on both sides of a window and guide the shading units. Each shading unit is composed of a moving member(210), a shading blade(220), and a rotary shaft(230). The moving members are moved along the guide bars. The shading blades are coupled to the moving members. The rotary shafts are coupled to the shading blades. The main drive unit is composed of a main motor(310), a drive wire(320), and a pulley(330). The angle regulation unit regulates the angle of the shading blades and is composed of an angle regulating motor(410), a winding roller(420), and an angle regulating wire(430).
