Description

  The present invention relates to a technique for preventing water leakage from a corner of a floor surface in an opposing groove for inserting both ends of a water stop plate formed on both walls of a passage.

  Conventionally, there are opposing grooves for inserting both ends of the water stop plate on both walls of the passage, the lower surface of the water stop plate is on the floor of the passage, and the both ends are on the inner surface of both opposing grooves via the water stop rubber. A waterproof device for a passage that crimps with a crescent has been developed (for example, Patent Document 1).

  However, a gap is formed between the inner surface of the opposite groove and the floor surface of the passage so that the water-stopping rubber at both ends does not reach the floor surface, and water leaks from the gap (FIG. 4, page 3, FIG. 4 above). (Gap between the front side inner surface 2 "and the elastic waterproofing rubber 4 ').
