Abstract

　渦巻き状ラップの段部高さを十分に高くしつつ、ラップ強度を必要かつ十分に確保することができ、しかもラップ加工が容易にできる三次元圧縮可能なスクロール圧縮機を提供する。一対の固定スクロール部材（１５）および旋回スクロール部材（１６）の渦巻き状ラップ（１５Ｂ，１６Ｂ）の先端面（１６Ｄ）とボトム面（１６Ｅ）とにそれぞれ段部（１６Ｆ，１６Ｇ）を備え、該段部よりも渦巻き状ラップの外周側において渦巻き状ラップ高さを内周側の渦巻き状ラップ高さよりも高くし、渦巻き状ラップの周方向および高さ方向に三次元圧縮が可能な構成としたスクロール圧縮機で、渦巻き状ラップの先端面（１６Ｄ）とボトム面（１６Ｅ）とに設けられる段部を複数段の段部（１６Ｌ，１６Ｍ）および（１６Ｆ，１６Ｇ）により構成するとともに、各段部の高さをそれぞれの段部の根元応力が略等しくなる高さに設定した。
