A scroll hydraulic machine which can prevent a key groove of an aluminum front case from being abnormally abraded even when lubricating oil runs out, and which can reduce the number of parts, is provided. The scroll hydraulic machine includes a fixed scroll, a swirling scroll performing a revolutionary swirling motion while engaging with the fixed scroll, an Oldham joint having a key for causing a swirling scroll to move in a revolutionary swirling motion while preventing the swirling scroll from rotating a front case, and a case body receiving the fixed scroll, The swirling scroll and the Oldham joint are positioned within a housing formed by attaching the front case to an opening portion of an end thereof. A key groove portion to which the key of the Oldham joint is fitted and a portion supporting a thrust force acted on the swirling scroll of the front case are made of a ferrous alloy.
