摘要：
A manufacturing tool (20) for forming a dynamic pressure groove (52) in an inner peripheral surface of a bearing sleeve (50) includes a tool shaft (21) for being rotated in a bore of the bearing sleeve while being moved in an axial direction thereof. Protrusions (25) are integrally and circumferentially arranged on an outer periphery of the tool shaft near a leading end (22) thereof. Machining tips (26) are integrally formed on outmost ends of the protrusions for machining the inner peripheral surface of the bearing sleeve to form the dynamic pressure groove therein.
