Abstract

　スクロール型流体機械(1)は、ラップ(44)の側面(44a)に位置づけられるテーパエンド(60a)から該ラップ(44)の立設される鏡板面(40a)に向けて傾斜したテーパ面(60)を有する根元部(58)と、根元部(58)を有するラップ(44)と対をなすラップ(42)に形成され、該ラップ(42)の側面(42a)に位置づけられる面取りエンド(70)から該ラップ(42)の先端面(42b)に向けて面取りして形成された面取り部(68)とを備え、面取り部(68)は、摺接面(66)の形成に伴い、根元部(58)と離間し且つ面取りエンド(70)から摺接面(66)までの距離がテーパエンド(60a)から摺接面(66)までの距離以上となる大きさに形成される。
