Claims (1)
- クランクケース圧縮掃気型の2サイクルエンジンにおいて、シリンダブロック(2)の内部にピストン(4)が往復運動する内部空間(2b)を形成するとともに、該内部空間(2b)のシリンダ面に軸心と平行に溝(21a・21b)を形成し、該溝(21a・21b)に隔壁部材(22・23)を設けて掃気経路(11a・11b)を形成し、該隔壁部材(22)は板状の部材を屈曲して、隔壁部(22a)と、両側の側壁部(22b・22c)により平面視コの字型に形成し、該隔壁部(22a)は、前記溝(21a)に隔壁部材(22)を設けたときに、該溝(21a)の中途部と、シリンダブロック(2)の内部空間(2b)とを隔てる略長方形の部材であり、該側壁部(22b・22c)は、該隔壁部(22a)の左右端部から延設される略長方形の板状の部材であり、該溝(21a)に隔壁部材(22)を設けたときに溝(21a)の壁面と当接して、該隔壁部材(22)を支持し、前記隔壁部材(22)に、2箇所の係止部(22e・22d)を設け、該係止部(22e・22d)は、前記隔壁部材(22)のそれぞれの側壁部(22b・22c)の下端部を90度折り曲げて形成し、前記シリンダブロック(2)とクランクケース(3)との接合面の、該シリンダブロック(2)側に形成された凹部(2c・2c)に該係止部(22e・22d)を嵌入係止し、前記溝(21a)とシリンダブロック(2)の内部空間(2b)との境界部分に、該隔壁部材(22)を支持するための突起(24)を、溝(21a)に沿って設け、前記隔壁部材(22)の隔壁部(22a)の外側部分に、該突起(24)の内側部分を当接させて、該隔壁部材(22)を支持し、該隔壁部材(22)の内部空間(2b)側への倒れ込みを阻止することを特徴とする2サイクルエンジン。
