To obtain excellent slidability and to reduce the cost of a device by forming a drum of a resin composite material and exposing and projecting out the composite material for sliding on the surface of a tape-sliding part.

The compounding material 2 for sliding of the surface structure of the tape-sliding parts 7-a, 8-a of the rotary drum 7 and the stationary drum 8 is allowed to bear sliding with the tape 1 while the resin material 3 is hardly brought into contact with the tape 1. The resin material 3 is selectively removed exclusive of the compounding material 2 from such surface by chemical or thermal means, by which the surface structure is obtd. The compounding material 2 is exposed on the surface of the resin molded goods and the compounding material 2 is put into the state projecting from the resin material 3.
