PROBLEM TO BE SOLVED: To provide a leakage prevention member capable of preventing water leakage between a through-pass hole and a tubular body even if a positional displacement occurs between the through-pass hole arranged at a plate-like body and the tubular body inserted into the through-pass hole.SOLUTION: A water-leakage prevention member 100 has a configuration in which a first seal part 101, a second seal part 102 and a connecting part 103 are integrally formed by resilient material. The first seal part 101 has a cylindrical part 101a with an outer circumferential shape corresponding to a hole shape of the through-pass hole and a pair of annular protrusions 101c protruded out of an outer circumferential surface of the cylindrical part in which both extremity ends of the pair of annular protrusions are spaced apart only by a distance corresponding to a thickness of a plate-like member in an axial direction of the cylindrical part. The second seal part 102 has an opening part having a hole shape corresponding to an outer circumferential shape of a tubular body. The connecting part 103 connects the first seal part 101 with the second seal part 102 without any clearance and a rigidity against a shearing force in a direction crossing at a right angle with the axial direction is smaller than those of both the first seal part and the second seal part.SELECTED DRAWING: Figure 2 |
