    摘要： A joined body includes: a first member having a pipe shape; and a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape provided with an insertion hole through which the first member is inserted. In a state where the first member is inserted into the insertion hole of the flange portion of the second member, the first member and the second member are joined with the first member pipe-expanded. A material of the second member is larger than a material of the first member in a spring-back amount.

    摘要： A steel plate frame and a thin plate are made of different materials. A plurality of through holes are formed in a portion of the thin plate to be placed on the steel plate frame. A plurality of projections 6c are formed on a support plate, each of the projections being allowed to be inserted into a corresponding one of the through holes. An adhesive is applied to a portion of the steel plate frame on which the thin plate is placed. The thin plate is placed on the steel plate frame, and the steel plate frame and the thin plate are bonded together by the adhesive. The support plate is placed on the thin plate to insert the projections into the through holes. The projections and the steel plate frame are welded to form a plurality of welded spots.

    摘要： A method for joining members includes: providing a wall surface body which is a die-molded article provided with a hole portion with a draft angle provided from its opposite end portions toward its center portion, a tubular body with a hollow shape, and an elastic body; inserting the tubular body into the hole portion in the wall surface body; inserting the elastic body into the inside of the tubular body; and compressing the elastic body in the direction of an axial line L of the tubular body to expand the elastic body outwardly in the radial direction of the axial line L, thereby deforming and expanding the tubular body to joint the tubular body to the wall surface body by press-fitting.
