Claims

[Claims for Utility Model Registration] 1. It is made of thick air-water-tight, heat-insulating, and flexible sponge or di-rubber, and has a concave water guide groove to surround the leakage point, and an outer groove on both sides of the water guide groove. The flange portion is positioned to surround the water leakage point of the water guide groove, and both the flange portions are fixed to both sides of the water leakage point to prevent water leakage and freezing due to this water leakage. A water leakage prevention member characterized by: 2. The water leakage prevention member according to claim 1, which is made of a plate material that does not easily attract water scale and is laminated on the inner surface of the water guide groove and the abutting surfaces of both flange portions connected thereto. 3. The water leakage prevention member according to claim 1 or 2, which is a registered utility model and is formed with an uneven part for promoting adhesion on the contact surface of the flange part.
