Abstract:
1. A scroll fluid machine comprising: a drive shaft having an eccentric shaft portion at one end; a stationary scroll comprising a stationary end plate having a stationary wrap; an orbiting scroll comprising an orbiting end plate having an orbiting wrap, said orbiting scroll being supported around the eccentric shaft portion of the drive shaft to turn via a bearing; a self-rotation preventing device for preventing the orbiting scroll from rotation around its own axis, the orbiting scroll being eccentrically revolved with respect to the stationary scroll while forming a sealed chamber between the stationary wrap and the orbiting wrap; and a bearing plate fixed to the orbiting scroll behind the orbiting scroll, an oil-supply hole being formed through the bearing plate in front of the self-rotation preventing device so that grease may be supplied from the oil-supply hole into a bearing of the self-rotation preventing device.
