PROBLEM TO BE SOLVED: To avoid such a problem that the seal performance of a side end is deteriorated, in a structure which connects both members in a state that a gasket is sandwiched and compressed between one member and the other member. ! SOLUTION: In a connecting region which opposes a mating member via a gasket 3 between both members 1, 2, there are arranged: flat edges 11, 12, 21 and 22 extending to a direction which is substantially orthogonal to a direction in which both the members 1, 2 are fastened to each other; first bevel edges 13, 14, 23 and 24 which bendly or curvedly extend to directions which are non-parallel with the flat edges 11, 12, 21 and 22; and second bevel edges 15, 25 which are located inside the first bevel edges 13, 14, 23 and 24, and bendly or curvedly extend to directions which are non-parallel with the flat edges 11, 12, 21 and 22, and whose cross angles γ with respect to fastening directions of their tangent lines are larger than cross angles α, β with respect to fasten |
