Abstract

Provided is a scroll fluid machine capable of effectively achieving performance of a tip seal installed in a tooth crest of a wall including an inclined portion. The inclined portion in which a distance between opposing surfaces of end plates facing each other gradually decreases from an outer peripheral side toward an inner peripheral side is provided. A tip seal () configured to make contact with a tooth base facing the tip seal () to perform sealing against fluid is provided in tip seal groove () formed in a tooth crest of a wall () corresponding to the inclined portion. In a stop state where a scroll () does not perform compression of fluid, an inclination height (Ls') of the tip seal () is smaller than an inclination height (Ls) of the wall ().
