摘要： Scroll fluid machine (1) in which the dislodgement of a slide bush (56) and a spring (61), which are provided in an eccentric bush (36), is prevented. Provided in receiving hole (58) of eccentric bush (36) are slide bush (56), which is movable in the direction of eccentricity, and spring (61), which biases slide bush (56) in a moving direction. A spring holding section (56b) and engagement projections (56a) are formed on slide bush (56). After slide bush (56) is placed in the receiving hole (58), engagement projections (56a) engage with eccentric bush (36) in a state in which slide bush (56) has been moved by the biasing force of spring (61), thus preventing slide bush (56) from falling off the receiving hole (58), and the spring holding section (56b) prevents the spring (61) from falling off the receiving hole (58).

摘要： To provide a scroll-type fluid machine in which the influence on power recovery efficiency of a clearance in an expansion section is reduced. A scroll-type fluid machine (100) includes: a scroll unit (20) in which a fixed scroll (3) and an orbiting scroll (4) are disposed and an expansion section (1) and a compression section (2) are formed; and a support part (30) that supports the orbiting scroll (3) so as to be able to perform revolving motion, the compression section (2) being driven by power recovered in the expansion section (1). A minimum clearance between a wrap (3L) of the fixed scroll (3) and a wrap (4L) of the orbiting scroll (4) in the expansion section (1) is set to be less than a minimum clearance between the wrap (3L) of the fixed scroll (3) and the wrap (4L) of the orbiting scroll (4) in the compression section (2).
