Abstract: A thickened part is formed in the first member. The thickened part has a protruded part that is convex on one side in the thickness direction of the first member, so that the thick portion is set thicker than the general portion as the other portion. At least a part of the second member overlaps a part of the first member that includes the thickened part from another side of the first member in the plate thickness direction, and the self-piercing rivet is driven into a fastening overlapped part that is a part that the second member overlaps the thickened part from a second member side, so as to fasten the first member and the second member.

Abstract: A wear-resistant iron-based sintered alloy made of a mixed powder including first hard particles, second hard particles, graphite particles, and iron particles is produced. The first hard particles are Fe—Mo—Ni—Co—Mn—Si—C alloy particles. The second hard particles are Fe—Mo—Si alloy particles. The mixed powder includes the first hard particles at 5 mass % to 50 mass %, the second hard particles at 1 mass % to 8 mass %, and the graphite particles at 0.5 mass % to 1.5 mass % when a total amount of the above particles is set as 100 mass %. In a sintering process, sintering is performed so that the hardness of the first hard particles becomes 400 to 600 Hv and the hardness of the second hard particles exceeds 600 Hv. Then, an oxidation treatment is performed so that a density difference between before and after the oxidation treatment in a sintered product becomes 0.05 g/cm3 or more.
