The insertion hole 5 is aligned with the bolt insertion hole 2 of the link body 1. Next, the end portion of the link body 1 is sandwiched and pressed using a press device, whereby the wedge portion 7 on one side of each hard stopper member 6 is cut into the inner surface of the upper wall and the inner surface of the lower wall of the link body 1 respectively. .

Even if a large input exceeding the coefficient) is applied, the rigid stopper member 6 is caught on the link body 1 and the prismatic extension 4 regardless of the holding force, and the contact between the link body 1 and the prismatic extension 4 is caused. Since slip on the surface is prevented, a high-strength bond can be obtained in the slip direction.

For example, a plate-like member or an elliptical ring may be used. When an elliptical ring is used, the coupling rigidity can be increased as in the case of a circular ring, and slip in the rotating direction can be prevented at the same time.

It is not always necessary to do so, and the rectangular columnar extension 4 is mounted with the hard stopper members 6 placed substantially concentrically with the bolt insertion holes 5 on both long sides of the prismatic columnar extension 4. The bolt insertion hole 5 of the prismatic extension 4 is inserted into the end of the link body 1 and the bolt insertion hole 2 of the link body 1 is inserted.
By pressing the end of the link body 1 in this state, the wedge portion 7 on one side of each hard stopper member 6 is cut into the inner surface of the upper wall and the inner surface of the lower wall of the link body 1 at the same time. The wedge portions 7 on the side may be made to bite into both long side surfaces of the prism-shaped extension portion 4. In this case, the gap when the prismatic extension 4 is inserted into the end of the link main body 1 is reduced, and the end of the link main body 1 is less likely to be crushed, so that the slit 10 described above can function effectively. it can.

する。Next, a second embodiment of the present invention will be described. FIG. 7 is an explanatory cross-sectional view for explaining a connecting structure of aluminum members according to the second embodiment of the present invention. This embodiment differs from the first embodiment in that a rivet 30 is used instead of the bolt 8 and the nut 9. The rivet 30 is inexpensive but does not act on the axial force, so it is unsuitable when coupling rigidity is required. However, in this embodiment, the rigid stopper member 6 is connected to the link body 1 and the corners regardless of the holding force. Since the sliding at the contact surface between the link main body 1 and the rectangular column-shaped extending portion 4 is prevented by being hooked on the column-shaped extending portion 4, the rivet 30 has a function of merely preventing each hard stopper member 6 from coming off. Is sufficient, and as a result, the connection using the rivets 30 can be enabled. Note that the other configuration and operation and effect are the same as those of the first embodiment, and the description thereof will be omitted.
