Abstract: PROBLEM TO BE SOLVED: To display stable dynamic pressure effect with high shape accuracy of a bearing surface by providing the bearing surface with dynamic pressure groove forming areas and other areas simultaneously formed on the inner peripheral surface of a bearing body formed of a soft metal. SOLUTION: A bearing surface 3c of a bearing 3 is formed by inserting a mold with shape corresponding to the bearing surface 3c of a finished product (bearing 3), into the inner periphery of soft metallic material 3' of approximately cylindrical shape and pressurizing a bearing surface forming area 3x' of an inner peripheral surface 3b' to the mold so as to simultaneously form the forming area of dynamic pressure grooves 3e of the bearing surface 3c, and other areas 3f. A process of eliminating burrs of the bearing surface 3c is therefore dispensed with, and worsening of cylindricity of the bearing surface 3c is prevented. Since the whole area of the bearing surface 3c is simultaneously formed by pressure application to the mold, the dynamic pressure grooves 3e formed with micro step difference of 2-4 μm can be formed with accuracy.
