Claims

[Scope of utility model registration request]

In a two-stroke engine cylinder in which a scavenging port 3 is formed in a wall 2 of a cylinder body 1, a starting end 4 of the scavenging port 3 is opened at a lower end surface 6 of the cylinder body 1, and a terminal end 5 is opened at an inner circumferential surface 7. A window hole 10 is formed in the peripheral inner wall 8 of the scavenging port 3 (in the outer wall portion 11 of the terminal spine 8a), a blind cover 12 is covered and fixed in this window hole 10, and the inner surface of the blind cover 12 is fixed. A cylinder for a two-stroke engine, characterized in that 14 is formed as a scavenging surface 15 suitable for guiding scavenging air and faces the scavenging port 3.
