Abstract

An upper oil pan (17) of an engine (1) includes a flange (171) with an oil pan abutment surface (172) that is fixedly coupled to a flange (111) formed on a cylinder block (11). The oil pan abutment surface (172) comprises a flat portion (1721) that is substantially parallel to a cylinder block abutment surface (112) of the cylinder block (11), a slanted portion (1722) that is slanted with respect to the flat portion (1721), and a vertical wall portion (1723) connecting the flat portion (1721) and the slanted portion (1722). The vertical wall portion (1723) is formed substantially perpendicular to the flat portion (1721). The cylinder block (11) and the upper oil pan (17) are fixedly coupled together via an interposed liquid gasket (31a). Thus, the seal structure in which the liquid gasket (31a) is adequately cured is provided, and sufficient sealing properties can be obtained with a small amount of material used. <IMAGE>

Description

technical field [0001] The invention relates to a sealing structure. In particular, it relates to a liquid packing sealing structure suitable for use in an oil seal between a cylinder block and an upper oil pan and / or an upper oil pan and a lower oil pan or the like in an engine. Background technique [0002] An example of a conventional liquid packing seal structure is disclosed in Japanese Patent Application Publication No. H11-173424, which employs a form-in-place packing for an engine oil seal structure. Specifically, in such a conventional liquid packing seal structure, a groove is provided near the center of the flange abutment surface on either of two members joined together by forming in situ (form -in-place) filler is a liquid filler connected together. When the two components are joined, the groove acts as a reservoir for the liquid charge. Especially when assembling an engine, a liquid filler is applied to the adjoining surface of a flange of one of the two par...
