GASKET STRUCTURE IN INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To enhance pressure resistance of a gasket between a cylinder head and a head cover.SOLUTION: A gasket 48 integrally includes: a mounting part 52 mounted on a mounting groove 49 so that one end part comes into contact with a closed end wall 49a of the mounting groove 49; and a flange part 53 which is connected to the other end part of the mounting part 52 so as to be configured by an inside flange portion 53a extending to the inward side of a cylinder head 25 and a head cover 26 from a virtual line VL which passes through a width direction center of the mounting part 52 and which extends in parallel with a holding direction of the gasket 48, and by an outside flange portion 53b extending from the virtual line VL to the outward side of the cylinder head 25 and the head cover 26. Extension length L1 of the inside flange portion 53a from the virtual line VL is set to be larger than extension length L2 of the outside flange portion 53b from the virtual line VL.
