PROBLEM TO BE SOLVED: To provide an apparatus for supporting an advertising board, where the apparatus is composed of simple and few component shapes and mounts the advertising board on the top of a vehicle. SOLUTION: An outer frame 8 is formed, by integrally molding L frames 9 and hollow frames 11 with screw grooves 10 so as to be provided with grooves 13 and 13. The outer frame 8 is disposed as a longitudinal outer frame 14 and a lateral outer frame 15, and both the frames are coupled by using corner fittings 16 to make frameworks 3 and 5. A vertical outer frame 4 consisting of the outer frame 8 is fixed to the corner fittings 16, and the frameworks are formed as the lower framework 3 and the upper framework 5. A speaker frame 6 is fixed to the lateral outer frame 15 of the upper framework 5, and a carrier frame 29 is fixed to the longitudinal outer frame 14 of the lower framework 3. By sliding the heads of bolts 26 in dovetail grooves 24 of both the frames 6 and 29, the mounting positions of a speaker and a carrier are made freely selectable. COPYRIGHT: (C)2005,JPO&NCIPI
