Claims

[Scope of utility model registration request]

Two belt-shaped rubber sheets of different thicknesses are overlapped and their longitudinal and side ends are glued together, and the outer surface of the thicker rubber sheet side has a cross section of approximately right triangular shape. The ridged body faces the upright surface toward the side end in the longitudinal direction, leaving the adhesive portion of the rubber sheet inward, and
On the other hand, on the outer surface of the thin rubber sheet side, a protrusion having a rectangular cross section is formed protruding from an intermediate band in the width direction of the rubber sheet. A rubber weir characterized by:
