It is sufficient that one type of press die is used for molding, but if the short tube portions 3 and 3 and the short tube portions 4 and 4 have the same diameter, the plate press products 1 are not necessarily connected to each other. It does not have to be the same. For example, the lengths of the short tubular portions 3 and 4 may be different between the plate pressed products 1, and the cross-sectional shape of the connecting portion 5 may be different.

By welding at the flange 6, as shown in FIG. 7, the strength of the link portion 15 can be further improved. This is particularly effective when the cylindrical bush type link 2 has a long link portion 15. This welding may be performed continuously along the longitudinal direction of the connecting portion 5, or may be performed at one or several locations in a part such as near the center in the longitudinal direction. Further, instead of this welding, one of the flanges 6 facing each other as shown in FIG. 8 may be bent and engaged with the other flange 6. Also in this case, it is possible to continuously engage along the longitudinal direction of the connecting portion 5, or to engage at a part thereof. Further, the flanges 6 on the outer circumferences of the short tube portions 3, 4 can be welded or engaged with each other in the same manner as the welding or engagement of FIG. 7 or FIG. It is also possible to form concavities and convexities between the flanges 6 at any position of the flanges 6 and engage these concavities and convexities. It is advisable to form these irregularities at the same time when the plate press product 1 is press-molded. Furthermore, it is also possible to rivet both flanges instead of the welding, engagement or concave-convex engagement.

どうしを溶接又は係合することは困難である。FIG. 9 and FIG. 10 are views showing a second embodiment. In this example, two plate press products 1 are arranged so that each flange 6 is on the side far from each other. The shape is opposite to the shape, and the cylindrical rubber bushes 7 and 8 are press-fitted into the cylindrical portions 13 and 14 formed thereby. Therefore, in the two plate press products 1, the concave surfaces of the connecting portions 5 face opposite to each other, and the connecting portions 5 are opened to be parallel to each other. Thus, since the two connecting portions 5 are separated from each other on both sides in the axial direction of the cylindrical rubber bushes 7 and 8, even if the input to the cylindrical rubber bushes 7 and 8 is inclined with respect to the longitudinal direction of the link portion 15, sufficient strength is obtained. Can be obtained. It should be noted that in this embodiment, the flange 6 has both connecting portions 5
Welding or engaging one another is difficult.

Further, in both of the above-described embodiments, the cylindrical rubber bushes 7 and 8 are press-fitted into the cylindrical portions 13 and 14 in a state in which the plate pressed products 1 face each other or are diametrically opposed to each other. With the flanges 6 of both plate pressed products 1 facing up or the flanges 6 of both plate pressed products 1 facing down, the short tube portions 3 and 3 and the short tube portions thereof. It is also possible to form the cylindrical bush type link 2 by press-fitting the cylindrical rubber bushes 7 and 8 into the cylindrical portions 13 and 14 formed of 4 and 4.
