To provide a hemming part structure of a vehicle body, capable of suppressing corrosion an outer panel and an inner panel regardless of whether adhesive used in a hemming part is conductive or non-conductive.SOLUTION: A hemming part structure of vehicle body includes: an outer panel 10; an inner panel 20; and adhesive 30 bonding the outer panel to the inner panel. An end part of the outer panel is folded to pack an end part of the inner panel, thereby constituting a hemming part. The adhesive 30 includes a thermally responsive microcapsule 31M containing a two-liquid mixed curable resin A and a thermally responsive microcapsule 32M containing a two-liquid mixed curable resin B. A resin of at least a part of an exposing area of the adhesive is covered with a coating 33 of the two-liquid mixed curable resin.SELECTED DRAWING: Figure 4

    【課題】 ヘミング部に用いる接着剤が導電性であっても非導電性であっても、アウターパネル及びインナーパネルの腐食を抑制することができる自動車車体のヘミング部構造を提供する。【解決手段】 自動車車体のヘミング部構造は、アウターパネル10と、インナーパネル20と、アウターパネルとインナーパネルを接合する接着剤30とを備え、アウターパネルの縁部は、インナーパネルの縁部を包み込むように折り返してヘミング部を構成し、接着剤30は、2液混合硬化型樹脂のA液を内包する熱応答性マイクロカプセル31Mと、2液混合硬化型樹脂のB液を内包する熱応答性マイクロカプセル32Mとを含み、接着剤の露出した部分の少なくとも一部の領域は、2液混合硬化型樹脂の被膜33で覆われている。【選択図】 図4
