<p><P>PROBLEM TO BE SOLVED: To provide an additional tightening joint structure capable of maintaining joining force of an additional tightening part of a platelike member and a shaftlike member for a long time. <P>SOLUTION: By pressurizing both sides of the shaftlike member inserted into a through hole of the platelike member and giving additional tightening deformation to one end of the shaftlike member, joining force is obtained by nipping force generated between a first joint face and a third joint face of both faces of the platelike member and tension force generated by swelling deformation onto an outside diameter side of the shaftlike member on a second joint face and a fourth joint face formed around the shaftlike member. For this reason, a gently inclined face (chamfered shape) is constituted as the fourth joint face in a corner part on an additional tightening side of the shaftlike member of the through hole. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
