Zusammenfassung:	There is provided an improved cylinder head cover that prevents the gas outlet for the blow-by gas from being cooled by structural improvements so that the gas outlet does not freeze or become clogged in a cold condition.A cylinder head cover 5 includes: a gas passage W through which blow-by gas g from a crankcase passes; and a gas outlet portion 8 protruding upward from a head cover upper wall 5A. The gas outlet portion 8 includes a protruding case portion 15 bulging upward from the head cover upper wall 5A so as to form an outlet passage 8A through which blow-by gas g passes, and an air layer 16 is formed outside the outlet passage 8A in the protruding case portion 15.
