Zusammenfassung:	PROBLEM TO BE SOLVED: To advantageously reduce a structural volume in an axial direction of an eccentric device and to simplify its assemblage. SOLUTION: This radial piston pump is provided with a rotary pump shaft 2 having a section 1 coupled with an irrotationally disposed eccentric ring 4, and a needle shaft bearing disposed on an outer circumferential surface of the eccentric ring 4, and a pump plunger 13 disposed in a pump casing in the form of a star to be extended in a radial direction toward the pump shaft 2 is supported by an end surface of a needle sleeve 9 of the needle shaft bearing. In this case, the needle shaft bearing is formed as a separate component unit in which loss of parts never occurs in such a way that the eccentric ring 4 is disposed to be positioned between both flanging mold parts 10, 11 inside the needle shaft bearing.
