Eaves by a glass are constituted by supporting a rear end by an external wall 3 and a top face by two supporting arms 5 arranged between the external wall 3 and a quadrilateral plate glass 1. The supporting arms 5 and the plate glass 1 are connected through universal joints 4, and the connecting sections are configured by an upper holding section 4f constituted to a case section 4c and a connecting screw 4g connecting the upper holding section 4f and a lower holding section 4a through the lower holding section 4a and the connecting hole 1a of the plate glass 1. An LED illuminating section 6 is configured to the lower holding section 4a, a power supply line 7a on the positive side connected to the LED illuminating section 6 is pulled in up to the inside of the external wall 3 through both universal joints 4 and the insides of the supporting arms 5 and the ground side 7b is pulled in up to the inside of the external wall 3 by using the universal joints 4 and supporting arm 5 themselves.
