形状としたことを特徴とする可撓ゴム接手。 In a flexible rubber joint that is integrally formed with an outer ring, an inner ring, and a membrane plate connecting them, which is used to connect a pipe and a wall opening, the outer ring has a seal on the outer periphery with the wall opening. It has a lip that also serves as a retainer, and the inner surface of the inner ring has an approximately arc shape with one end having approximately the same dimensions as the outer diameter of the connecting pipe and the other end having dimensions slightly smaller than the outer diameter of the connecting pipe. A flexible rubber joint characterized in that the inner ring has a swash plate shape starting from the larger diameter side and toward one end of the outer ring.
