<p>PROBLEM TO BE SOLVED: To provide a scroll type fluid machine that can make a PV value of a rotation stop mechanism small and suppress noise from being generated at low cost.SOLUTION: A rotation stop mechanism 30 for a movable scroll member includes a circular hole 31 formed on the side of an end plate of the movable scroll member, a pin 32 projected on the side of a thrust reception part 17 of a front housing, and a disk 33 which has an eccentric hole 33a and is accommodated in the circular hole 31 with a gap left, and the pin 32 is fitted in the eccentric hole 33a with a gap left. Here, SPOR<AOR<LPOR holds the slewing radius AOR of the movable scroll member defined by contacting between both laps of a fixed scroll member 2 and a movable scroll member 3, the maximum allowable slewing radius LPOR of a movable scroll defined by the gap between the circular hole 31 and disk 33 and the gap between the eccentric hole 33a and pin 32, and the minimum allowable slewing radius SPOR.</p> |
