摘要： A fill limit vent valve includes a float valve, a housing, and a lid. The housing includes a cylindrical outer wall and a tubular portion. The outer wall has a central axis. The tubular portion accommodates the float valve. The lid is placed on the upper end of the tubular portion and has a communicating opening. The housing includes a fuel passage that has an inlet and a discharge port. The discharge port is connected to the communicating opening. A section of the tubular portion that faces the fuel passage is constituted by a curved surface. A guide wall that has at least one guide surface is provided between the fuel passage and the inlet. A straight line on the curved surface that is parallel with the central axis is defined as a generatrix. The guide surface extends along the curved surface while being inclined relative to the generatrix.
