By filling the inside of the horn with a waterproof plug (rubber plug) 6, seawater etc. are prevented from entering into the horn 3. When blowing, air pressure from a compressor (not shown) is supplied from the passage 1a in the frame 1 of the horn 3 to blow away the waterproof plug 6. A string 7 is provided to prevent the waterproof plug 6 from being lost.
