PURPOSE:To obtain a compact engine by dividedly forming a breezer chamber inside a cylinder head cover and forming a guide passage by utilizing a part of a cam chain chamber and introducing the blow-by gas, etc. formed in a crank chamber into the breezer chamber. CONSTITUTION:A plate 12 is fixedly installed inside a cylinder head cover 11, and a breezer chamber 13 is dividedly formed between the both 11 and 12. While, at one edge part of a cylinder head 14, a partitioning wall 16 is formed along the side wall 15, and a passage part 17 dividedly formed by the both 15 and 16 communicates to the breezer chamber 13 through a hole 18 formed at one edge part of the plate 12. Further, the both sides of a cam chain guide 19 are attached in slidable ways onto the both side surfaces of the side wall 21 of a cylinder block 20, and a passage part 23 is dividedly formed by the both 19 and 21 and the cylinder head gasket 22, and said passage part 23 communicates to the passage part 17 through a hole 24 formed onto the gasket 22. |
