PURPOSE: To doubly prevent water from entering inside by a groove part and an extended projection by positioning the extended projection of a rear surface advertising board on the outer side of the groove part of a front surface advertising board, at the time of overlapping the front surface advertising board and the rear surface advertising board. CONSTITUTION: The rear surface advertising board 10, provided with an illuminating lamp inside and the front surface advertisement board 50 for fixing and holding an advertising sheet A, are made openable and closable by a hinge or the like. Then, at the time of closing the front surface advertising board 50 and the rear surface advertising board 10, the extended projection 18 of the rear surface advertising board 10 is oppositely positioned on the outer side of the groove part 55d of the front surface advertising board 50. Thus, in the case that the water flows into a device through a clearance 60 between the front surface advertising board 50 and the rear surface advertising board 10, from rain or the like, the water is made to flow along many recessed grooves 18', formed at the extended projection 18 of the rear surface advertising board 10. Further, the water overflowing from the recessed grooves 18' is made to flow along the groove part 55d of the front surface advertising board 50 positioned on the inner side, especially along the recessed groove 55e formed at the groove part 55d, and the water is prevented from flowing into the device.
