摘要： A scroll fluid machine is provided to cool a driving shaft by inflow of external air into a cooling hole, and to prevent cooling-finished air from being entered into the cooling hole by including auxiliary fins. A scroll fluid machine comprises a driving shaft(6), a fixed scroll(33), an orbiting scroll(5) and a cooling fan(8). The driving shaft has an eccentric axial portion at one end and has an axial cooling hole through which cooling external air sucked from a front end flows to cool the driving shaft, and is discharged from a rear end. The fixed scroll has a spiral fixed wrap. The orbiting scroll has a spiral orbiting wrap which engages with the fixed wrap to form a compressing chamber between the fixed and orbiting wraps. The orbiting scroll is rotatably secured around the eccentric axial portion of the driving shaft. The cooling fan is rotatably secured on the driving shaft, and comprises a base plate that has a main fin on a rear surface and a plurality of auxiliary fins on a front surface. The driving shaft enables the cooling fan to rotate to cool a side of the fixed scroll by the main fin. The plurality of auxiliary fins prevents cooling-finished air from invading into the cooling hole of the driving shaft.
