ABSTRACT:
In a scroll-type fluid machine in which a movable scroll member (3) is placed between a front housing (1) and a fixed scroll member (4), the movable scroll member is elastically urged towards the fixed scroll member by an urging member. The movable and the fixed scroll members are engaged with each other to form a compression space (6) therebetween. It is preferable that the urging member is composed by at least one of races (24, 25) of a ball coupling (5) which is placed between the stationary and the movable scroll members and is for preventing the movable scroll member from being rotated relative to the fixed scroll member.
