摘要： A vehicular structure includes: a first member formed in a tubular shape and having protrusions on an outer periphery thereof; and a second member formed in a tubular shape and having a locking wall with a hole in which the first member is inserted. The first member is joined to the second member such that a portion of the first member that is inserted in the hole of the second member is expanded, and the protrusions are in contact with the locking wall of the second member.

摘要： A structural member includes an inner member and an outer member formed of a material different from that of the inner member, the outer member being positioned outside the inner member so as to surround the inner member and including a first adjacent surface adjacent to an outer surface of the inner member, wherein an insulator is disposed between the first adjacent surface and a second adjacent surface of the inner member, the second adjacent surface being adjacent to the first adjacent surface.

摘要： A side member (example of second member) having a hollow shape is inserted into holes formed in a cross member (example of first member) (member insertion step). The cross member and the side member are joined by caulking by expanding an insertion portion of the side member from the inside of the insertion portion (caulked junction step). The insertion portion of the side member is a portion inserted into the cross member.

摘要： A method of bonding a first frame member and a second frame member includes: a protrusion formation step of forming a protrusion in a predetermined region of a plate by press fabrication; a stacking step of producing such a stack body of flanges and the plate that a leading end of the protrusion of the plate contacts with the flange and the flange is disposed between the flange and the plate; and a welding step of welding the protrusion to the flange by applying welding current between a pair of electrodes while the stack body is sandwiched between the pair of electrodes so that the protrusion is pressed against the flange.

摘要： Structure including joint structure of dissimilar materials comprises a roof panel and a skeletal body. The roof panel has a bent portion at its end and is a panel member made of an aluminum alloy. The skeletal body has a support portion for supporting the first member and is made of steel. The roof panel and the skeletal body are joined by continuous welding of a vicinity of an apex of the bent portion of the roof panel and the support portion of the skeletal body, a reinforcing plate is joined to the roof panel at least partially along the joining portion with the skeletal body.
