Beschreibung
Zusammenfassung:	The present invention makes a lap clearance between a fixed scroll and an turning scroll as small as possible to suppress leakage of compressed fluid from a compression chamber in a compression operation, thereby improving a compression efficiency. Provided is a scroll-type fluid machine characterized by comprising: a fixed scroll having a scroll lap portion; and an orbiting scroll that is provided to face the fixed scroll and that has a scroll lap portion turning so as to form a plurality of compression chambers in a clearance relative to the lap portion of the fixed scroll, wherein the lap portion of at least one of the fixed scroll and the turning scroll is provided with, in a predetermined region, a recessed portion on one lateral surface thereof and a protruding portion on the other lateral surface thereof.
