PROBLEM TO BE SOLVED: To prevent separation of a housing member.SOLUTION: There are provided: projection parts 71, 72 which are connected to a housing member 21 and have parts that are inside the housing 2 and extend nearer the housing member 22 side than joint surfaces 21a, 22a of the housing member 21 and the housing member 22 and projection parts 73, 74 which are connected to the housing member 22, have parts inside the housing 2 and extending nearer the housing member 21 side than the joint surfaces 21a, 22a, and cross the projection parts 71, 72 viewed from the cross section orthogonal to the joint surfaces 21a, 22a and a ceiling agent 11 which is applied to the joint surfaces 21a, 22a and joins the housing member 21 and the housing member 22. A foaming material 10 is filled in a part ranging from an end part opposite the part where the projection parts 71, 72 and the projection parts 73, 74 are in contact with the housing 2 to the part where the projection parts 71, 72 and the projection parts 73, 74 cross and between the projection parts 71, 72 and the projection parts 73, 74.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】ハウジング部材の分離を防止すること。【解決手段】ハウジング部材21と接続し、ハウジング2の内部であってハウジング部材21とハウジング部材22の接合面21a、22aよりもハウジング部材22側に延びる部分を有する突起部71、72と、ハウジング部材22と接続し、ハウジング2の内部であって接合面21a、22aよりもハウジング部材21側に延びる部分を有し、接合面21a、22aに対して垂直な断面から見て突起部71、72と交差する突起部73、74と、接合面21a、22aに塗布され、ハウジング部材21とハウジング部材22とを接合するシーリング剤11と、を備え、発泡材10は、突起部71、72及び突起部73、74がハウジング2と接続する部分とは反対側の端部から、突起部71、72と突起部73、74が交差する部分までの間であって突起部71、72と突起部73、74の間に充填されている。【選択図】図4
