A two-stroke cycle combustion engine of an air scavenging type includes one or more scavenging passages (13, 14) for communicating a crank chamber (2a) and a combustion chamber (1a) with each other, an air passage (10) for supplying an air (A), an introducing passages (16) for introducing the air (A) from the air passage (10) into an upper portion of each scavenging passage (13, 14) from a direction radially outwardly of a cylinder block (1), and a covering member (21) for covering the introducing passage (16) from an outer side. The covering member (21), the upper portion of each scavenging passage (13, 14) and a part of the introducing passage (16) are formed integrally with each other by a scavenging block (20). |
