悪くする。さらに、胴に固定された太陽電池は、リード
バネの反力により、長期間のうちにはうきあがり風防ガ
ラスと接触する事が予測される。The windshield warps and contacts the solar cell due to processing distortions and the like that occur when the windshield is fixed to the body. Further, due to the change in atmospheric pressure, the vicinity of the center of the windshield is bent, and the solar cell and the windshield may further contact with each other. When both of them come into contact with each other, interference fringes (Newton's ring) and wetting phenomenon occur around the contact portion, resulting in a very bad appearance. Further, it is expected that the solar cell fixed to the body will be heated up and contact the windshield for a long period of time due to the reaction force of the lead spring.

It is something to try. At the same time, it intends to provide a thin structure.

Even if these two come into contact with each other, interference fringes and wetting phenomenon do not occur. If the print / seal surface is applied to the windshield side and is thicker than the visible light wavelength, interference or wetting may occur due to light from the outside even if the print / seal surface contacts the solar cell. There is no.

The inner surface print 2 applied to the inner surface of the windshield 1 can be made into characters or figures as in the illustrated example. Setting this printing position in the center part where deformation easily occurs in addition to the periphery of the windshield has a great effect of preventing interference fringes and wettability, and the printing color is white that transmits as much as possible in the visible light range. System is desirable.
