<p>The invention provides a heat insulating structure of a gas channel joint part, which can prevent the generation of cracks and improve the reliability. The heat insulating structure of the gas channel joint part includes: an exhaust manifold which is provided with a channel for the gas flowing in a cylinder of an engine and a cylinder cover (61) being fastened on the engine via a flange part (22), a heat separating plate (10) which is configured between the engine and the exhaust manifold and is provided with a joint part (11) being fastened at the engine together with the flange part (22) and an inclined part (16) and support leg parts (17) protruding toward the outer side of the outer edge (23) of the flange part (22). The flange part (22) has upper side protruding part shapes (24d, 24e) arranged at the outer edge (23) of the inclined part (16) and support leg parts (17) and protruding toward the inclined part (16) and support leg parts (17), and the joint part (11) is provided with a notch (14) in the position opposite to the outer edges of the upper side protruding part shapes (24d, 24e).</p> |
