To form a rotation jungsimbong 103, a metal material in the center of the fan 102, which is formed in a film-base been to print a variety of picture in the body 101, the upper portion of the mobile ramp (100) formed in the tubular, and the rotation jungsimbong 103 air populated more by the heat of the bulb (1) in a state suspended by the magnetic force of the magnet 201. it has been installed on the upper portion of the support 200 through the fan 102 by the convection action breakout body 101 rotates to have to be, by improving a method for hanging in the way beneath the support system that support so that the mobile ramp can be rotated as well as to prevent the fan rotation center of the mobile ramp as in the prior art to be drilled by the tribological , due to the deterioration of the rotation center will be very useful inventions that can prevent the rotation of the mobile ramp function is lost.
