摘要： A sintered component forming step is for forming a sintered component by powder molding. An insert forming step is for forming a sintered insert component in which an exterior component is integrated on an outer peripheral portion of the sintered component. One or more grooves or ridges are formed on an outer peripheral portion of a region except for one end portion of the sintered component in the sintered component forming step. The insert forming step includes a step for bringing the outer peripheral portion of the end portion into contact with an inner peripheral surface of an insert forming mold along a circumferential direction and covering the one or more grooves or ridges by the insert forming mold with an interval to form a cavity on an outer peripheral portion of the sintered component and a step for filling a melted material in the cavity.

摘要： A bearing for a motor-type fuel pump comprises a Zn—P—Ni—Sn—C—Cu-based sintered alloy and has corrosion resistance to a coarse gasoline containing sulfur or an organic acid(s); superior wear resistance; and superior conformability with a shaft as a counterpart. The bearing is suitable for use in a downsized fuel pump and has a structure in which a base comprises 3 to 13% by mass of Zn, 0.1 to 0.9% by mass of P, 10 to 21% by mass of Ni, 3 to 12% by mass of Sn, 1 to 8% by mass of C and a remainder composed of Cu and inevitable impurities. The base also comprises a solid solution phase of a Zn—Ni—Sn—Cu alloy. A Sn alloy phase containing no less than 15% by mass of Sn is formed in grain boundaries of the base. Pores have a porosity of 8 to 18% and free graphite distributed therein.

摘要： A die having a cavity and a lower punch fitted into the cavity. The cavity is divided and the parts slide along a division plane passing through the cavity parallel to the fitting direction of the die and the lower punch. The divided cavity parts are placed in a state of alignment along the division plane. The divided cavity parts are each filled with raw material powder. The die and the lower punch are then slid along the division plane, whereby the divided cavity parts are combined as the original cavity. The raw material powder in the cavity in a combined state is compressed by an upper punch and the lower punch.
