Dissimilar material joining member, dissimilar material joining structure, and dissimilar material joined body manufacturing method

摘要

A dissimilar material joining member includes a tubular portion, a flange portion (24), a deformation-scheduled portion to be clinched, a first joining component (14) made of metal, and a second joining component (16) made of metal. The tubular portion passes through a first joining-object member (18) made of resin. The flange portion (24) is extended in a flange shape to a radially outer side of the tubular portion from one axial end of the tubular portion. The deformation-scheduled portion is the other axial end side of the tubular portion. In the first joining component (14), the deformation-scheduled portion holds the first joining-object member (18) between the deformation-scheduled portion and the flange portion (24) by being bent such that a center portion in a direction along the axial direction is expanded to the radially outer side to form a fold-back portion when a compressive load equal to or greater than a predetermined value is axially applied to the tubular portion.
