Hello Jun Kitsukawa. The adapter most commonly used is made by Roundhouse Engineering in England.
They have a web site at http://www.roundhouse-eng.com/ There part number for this part is GFA and the cost is GBP 8 that is 8 Pounds Sterling. An idententical part is available from Sulphur Springs Steam Models in America. They have a web site at http://www.sssmodels.com/ Their part number is TGF1 and the cost is $US 17.50 Both of these companies give excellent service, and will export, and do take credit cards. I usually have stock of these filling adapters, but have none in stock at the moment, and they are not expected for a month or two. Jim Gregg. Precision Industrial Model Makers. Western Australia.
