<p>A scroll fluid machine that provides solutions to failures caused by an orbiting scroll tilting while being orbitally driven and that has improved performance and durability is provided. The scroll fluid machine includes a pair of scrolls, that is a stationary scroll and an orbiting scroll, including spiral wraps (31) vertically disposed on end plates (30), wherein the stationary scroll and the orbiting scroll are engaged by making the spiral wraps (31) oppose each other with the phases shifted, and offset parts (36, 37) are provided, in a direction that reduces the wrap thickness, on a ventral surface and a dorsal surface of a tooth-tip part of the spiral wrap (31) of at least one of the stationary scroll and the orbiting scroll, from the inner circumferential end to the outer circumferential end of the spiral wrap(31).</p> |
