PROBLEM TO BE SOLVED: To provide a radial piston type fluid rotating machine capable of maintaining a pintle in a non-rotation condition even if a cylinder block is displaced and the pintle is also displaced by following it and maintaining a clearance between the cylinder block and the pintle at fixed size. SOLUTION: The pintle 3 is elastically supported on a case 1 through a slipper seal 27, and an Oldham's coupling 30 is provided between an end part of the pintle 3 and the case 1. Both end parts of a cylinder bore part 6 in the cylinder block 4 are supported by a pair of bearings 7. Cancel ports 20a, 20b for high pressure communicating with a high pressure port 15 are formed in sections on both sides of a low pressure port 16 arranged by opposing to the high pressure port 15 formed in the pintle 3.
