PROBLEM TO BE SOLVED: To reliably seal a take-out part for taking out the end part of an electric heater from a liquid tank by brazing.SOLUTION: An end part 1 of an electric heater is taken out to the outside by passing through a cylindrical member 3 fixed to a tank while passing through the wall surface of the tank. The opening parts on the inside and outside of the tank in a gap between the end part 1 and the cylindrical member 3 are brazed by an inside wax member 10 and an outside wax member 11 to seal the take-out part of the end part 1 of the electric heater from the tank. First gap intercepting members 8, 16, and second gap intercepting members 9, 17 for intercepting the gap between the end part 1 of the electric heater and the cylindrical member 3 are provided, and the inside wax member 10 and the outside wax member 11 which are brazed are thereby made to stay in the vicinity of the opening part to reliably seal the opening by brazing.

    【課題】液体タンクから電熱ヒータの端部を取り出す取り出し部の、ろう付けによるシールを確実に行なう。【解決手段】電熱ヒータの端部1はタンクの壁面を貫通してタンクに固定された筒状部材3を貫通して外部に取り出される。端部1と筒状部材3の隙間のタンクの内側と外側の開口部を内側ろう部材10と外側ろう部材11でろう付けすることで、電熱ヒータの端部1のタンクからの取り出し部を密閉する。電熱ヒータの端部1と前記筒状部材3との隙間を遮断する、第1の隙間遮断部材8,16と第2の隙間遮断部材9,17とを備えることで、ろう付けされた内側ろう部材10と外側ろう部材11とを隙間の開口部付近に留めて、ろう付けによるシールを確実に行なわせる。【選択図】図1
