摘要： PROBLEM TO BE SOLVED: To provide a water sealing device for a vehicle capable of surely performing opening-closing of a drain pipe by a float and restraint of an atmospheric pressure variation, by preventing the float and a lower valve seat from becoming a sticking state via foreign matter.SOLUTION: This water sealing device for the vehicle includes a float chamber 12 having an upper valve seat 15 and the lower valve seat 16 for cutting off the drain pipe by abutting on the float 17 for vertically moving in response to a variation in a water level, and a drain trap 14 for setting the water level in the float chamber 12. A peripheral projection piece 18 having the lower valve seat on the inner peripheral edge is projected in a lower part of the float chamber 12, an upper surface of the peripheral projection piece is set in the horizontal direction or in a downward gradient of proceeding to the lower valve seat, and an angle to a horizontal line of the downward gradient is set less than a crossing angle of a tangent of a float outer peripheral surface passing though an abutting point between the float and the lower valve seat and the horizontal line.
