<p><P>PROBLEM TO BE SOLVED: To provide a fluid machine configured to achieve weight reduction and space-saving by an improvement in a rigidity increased structure of a housing. <P>SOLUTION: The fluid machine includes a pulley rotatably supported by the housing, and compresses or expands fluid by using torque of the pulley rotated by driving an endless belt wound on the pulley so as to wrap a part of the outer periphery of the pulley. In the fluid machine, the housing is constituted so that rigidity in an area outside of a range of a belt wrapping angle, becomes smaller than rigidity in an area in the range of the belt wrapping angle when viewed from a rotary shaft of the pulley. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
