PROBLEM TO BE SOLVED: To automatically cool an eccentric shaft part integrated with a driving shaft, its bearing and other peripheral member by using outside air by introducing the outsider air from the periphery of a housing in response to operation by installing one air fan on the driving shaft in a scroll fluid machine. SOLUTION: The outside air sucked by a primary intake hole 18 arranged in a proper place of the housing 1 is delivered from the other part of the housing 1 via various rotary parts in the housing 1 by the one air fan 15 arranged in a proper place of the driving shaft 9. A secondary intake hole is arranged in the proper place of the housing 1 for sucking and mixing new outside air by the pressure reduction action in the housing 1 by the outside air sucked and delivered by the air fan 15.
