2. Description of the Related Art
It takes a little time to get in and out of a vehicle and it doesn't matter to take long time to get in and out of a vehicle in normal times, but when it rains, a person is exposed to the rain as long as the time. Further, when a person gets into a vehicle with a wet umbrella in the rain, the rainwater on the umbrella causes inconvenience such as getting the interior of a vehicle wet.
Further, in a heavy rain such as a shower, even without an umbrella, a person is necessarily fully exposed to the rain while getting into and out of a vehicle. Patients, the handicapped, or the old who takes more time to get in and out of a vehicle further feels this inconvenience.
Further, when a person with a heavy load gets in a vehicle, he/she gets in the vehicle after put the load into the vehicle or gets in the vehicle and then puts the load into the vehicle, so not only he/she, but the load is exposed to rain.
In order to solve this problem, there is a rain shield system for allowing a person to more conveniently get in a vehicle by blocking rain in the related art. The system includes a frame box fixed to the roof of a vehicle and a rain shield that has the function of a sun visor and can be drawn out from the frame box, and the rain shield is drawn out and blocks rain by a series of control processes.
However, the rain shield system has a poor external appearance, requires a box that is separated manufactured and then mounted on the roof of a vehicle, and requires remodeling of much of the original shape of a vehicle for installation.
Further, the rain shield system illustrated in FIG. 1 requires a small motor for operating the rain shield, so it is difficult to manufacture and install the system.
