A supply body, a passage for guiding the resin supplied to the resin coating chamber from the outer peripheral side to the tubular cloth, and a thickness determining portion for determining the thickness of the resin coated on the inner and outer surfaces of the tubular cloth in the resin coating chamber, Is provided with an inflow chamber communicating with the resin supply body, and the mandrel penetrates through the center of the inflow chamber, and the outer diameter of the mandrel in the inflow chamber is set to be smaller than the inner diameter of the tubular cloth, so that the outer circumference of the mandrel is reduced. And a space is formed between the inner circumference of the tubular cloth and the resin that has flowed into the inflow chamber and enters the space through the tubular cloth. An inner diameter defining portion with an outer diameter that is approximately the same as the inner diameter, and An outer diameter defining portion having an inner diameter substantially the same as the intended outer diameter of the oil-coated tubular cloth, the outer diameter defining portion being provided below the outer peripheral passage and the inner peripheral passage of the resin coating chamber, and the inner diameter defining portion. A device for coating the peripheral surface of the tubular cloth with a synthetic resin, which is positioned in a position corresponding to the outer diameter defining portion of the mandrel.
