In the drawings, 12 is a second branch pipe, 13 is a third branch pipe, 14 is a fourth branch pipe, 19 is a gathering part, 28 is a flange, and 44 is a thermal deformation means.

Claims

[Claims for Utility Model Registration] (1) In an exhaust manifold in which flanges are provided at the ends of the first to fifth branch pipes and the flanges are attached to the cylinder head of an in-line five-cylinder engine, A deformation absorbing means is provided, and the thermal deformation absorbing means is used to compensate for the difference in length between the second branch pipe and the third branch pipe, and between the third branch pipe and the fourth branch pipe.
A flange structure of an exhaust manifold characterized in that it is located between a branch pipe and a branch pipe having a larger difference in length. (2) In an exhaust manifold in which a flange is provided at the end of the first to fifth branch pipes and this flange is attached to the cylinder head of an in-line five-cylinder engine, the flange is provided with a thermal deformation absorbing means such as a notch and The deformation absorbing means is the second branch pipe;
A flange structure for an exhaust manifold, characterized in that the flange structure is located between a third branch pipe and between the third branch pipe and the fourth branch pipe, whichever is closer to a gathering part of the branch pipes.
