PROBLEM TO BE SOLVED: To establish a high reliability joining structure for metal members having different material characteristics in which the impact strength of the joining members is heightened. SOLUTION: According to this joining structure, one metal member 1 is joined with another metal member 2 having less rigidity than the former, wherein if the angles to the free edge at the end of the joining surface of the former member and the latter member are both below 90 deg., the angle to the free edge at the end of the joining surface of the remaining metal member part should be below 90 deg. In joining the two metal members 1 and 2, if either of the angle to the free edge at the end of the joining surface of the former member and latter member is below 90 deg., the angle to the free edge at the end of the joining surface of the remaining metal member part should be below 90 deg. |
