Claims (1)
の拡張室と、これら拡張室を順次直列に連通させる狭隘
路とを設けて、燃料タンク内の燃料蒸散ガスを上記拡張
室および狭隘路を経て大気中へ流出させるガス流出通路
を形成し、このガス流出通路は、最下流側の拡張室から
上流側へ向かって漸次下降して設定されていることを特
徴とする燃料タンクのキャップ。A cap that closes a fuel filler port of a fuel tank, and is provided with a plurality of expansion chambers and a narrow passage that communicates these expansion chambers in series, and allows the fuel evaporated gas in the fuel tank to flow through the expansion chambers and the narrow passage. What is claimed is: 1. A cap for a fuel tank, wherein a gas outflow passage is formed to cause gas to flow out into the atmosphere, and the gas outflow passage is set to gradually descend from an expansion chamber on the most downstream side toward an upstream side.
