ABSTRACT:
There is provided a fluid machine able to secure a sectional area of a passage sufficient for gaseous fluid flow from a suction port to a compression mechanism, while able at the same time to achieve a reduction in size of the outline shape. In a scroll compressor where a scroll compression mechanism is housed within a housing having a funnel shaped, a compression mechanism main body of the scroll compression mechanism is arranged in a wide opening section of a front housing, and a compression mechanism driving section is arranged in a narrow section, a concave section is formed on the outside of a thrust receiving surface which is positioned on a bottom surface of the wide opening section and which supports the compression mechanism.
