A scroll fluid machine comprises a stationary scroll and an orbiting scroll between which a sealed space is formed. The orbiting scroll is eccentrically revolved with respect to the stationary scroll around a drive shaft via a bearing. An oil-supply hole is formed at the orbiting scroll so that grease may be supplied into the bearing for lubrication; There is a self rotation preventing device for the orbiting scroll and another oil supply hole to that device.
