PROBLEM TO BE SOLVED: To improve rust performance between both jointed members while assuring joint strength between two members for a vehicle, with ease at a low cost.SOLUTION: A mastic sealer 4 in which zinc powder is mixed by 20-60 wt.% is applied linearly along length direction, for jointing a reinforcement 3 to an outer panel 1. Thus, with a so-called lump generated at an application start point and an application end point of the mastic sealer 4, even if water remains in a region surrounded with lumps of the outer panel 1, the reinforcement 3, and the mastic sealer 4, occurrence of rust is suppressed by sacrifice corrosion-proof effect of zinc in the mastic sealer 4.

    【課題】簡単かつ安価に、車両用の2つの部材の接合強度を確保しつつ、接合される両部材間の防錆性能を向上できるようにする。【解決手段】20〜60重量%の亜鉛粉が混在されたマスチックシーラー4がリインフォースメント3の長手方向に線状に塗布してアウターパネル1にリインフォースメント3を接合する。そのため、マスチックシーラー4の塗布開始点および塗布終了点に生じるいわゆるダマにより、アウターパネル1、リインフォースメント3およびマスチックシーラー4のダマにより囲まされた領域に水が溜まっても、マスチックシーラー4中の亜鉛の犠牲防食効果によって、錆の発生を抑制することができる。【選択図】図2
