<P>PROBLEM TO BE SOLVED: To effectively prevent a contact portion of dissimilar metal from being electrically eroded with a simple structure. <P>SOLUTION: In a vehicle body structure and its manufacturing method, a vehicular structure (a shock absorbing member 3) for a vehicle made of an aluminum alloy casting material is coupled to a vehicle body side member (a rear side frame 1) made of a ferrous material. The vehicular structure is provided with a mounting flange 19 connected to the vehicle body side member through a connection member (a connecting bolt 18) and a bobbin-like member 31 formed of ferrous material having a through hole of the connection member. The body of the bobbin-like member 31 is cast in the mounting flange 19 with the end surface of the bobbin-like member 31 projected outward from the end surface of the mounting flange 19. <P>COPYRIGHT: (C)2012,JPO&INPIT |
