The present invention relates to an electric-powered sun visor for a vehicle that is developed or returned from/to the outside of the front surface glass or the rear surface glass at the interior of the vehicle in an electrically powered manner so as to prevent a driver's or passenger's field of vision from being interrupted by the sunlight entering the driver seat or the passenger seat, and more specifically, to an electric-powered sun visor for a vehicle that is provided with an actuator serving as a power transmitting part, a helical screw as a movement inducing part, slide gears as horizontal distance moving parts, linkages as folding parts, a screen roll as a tension maintaining part, a fixing part having a center stopper, shaft guides and screen roll guides, a screen part, a mounting frame and base covers, whereby the developing and returning operations of the electric-powered sun visor can be accurately performed, the amount of loss of the power transmitted can be substantially decreased to enhance the efficiency of the electric-powered sun visor, the developing and returning operations of the electric-powered sun visor can be easily performed to make it very convenient in use, the electric-powered sun visor can be developed to long width to increase the shading area, the generation of noise when the electric-powered sun visor is developed or returned can be minimized, the movements of the developed shading screen can be prevented, the balance of the force of developing or returning the electric-powered sun visor can be uniformly maintained, the sagging and wrinkling of the shading screen can be prevented, and it is easy to be mounted on the vehicle to improve the mounting operation, the outer appearance of the electric-powered sun visor can be improved when the electric-powered sun visor is mounted, and the driver's or passenger's field of vision can be protected from the sunlight to ensure excellent vision and safe driving. |
