A method and device for supporting a structure above a fixed surface. In other words, in the present applying mechanism, a part of the guide sheet 33 has a shape of avoiding the oil application roller 16 that has a high temperature. With the conductor film formed in close contact with the dielectric, deterioration of the Q value and the like caused by instability of connection at the corners can be suppressed even when a radio frequency induced current flows from the cylindrical portion over the two flat portions. Passages for flowing air between the inside of the boot and the outside of the boot are formed on the one-end fitting portion and the annular lip portion.
