Abstract

PURPOSE:To couple simply surely an arm body with a bearing tube, namely manufacture a link by additionally providing a polygonal short pipe on a flange of an arm body while inserting a polygonal bearing tube in the short pipe and calking said tube fixedly to said pipe. CONSTITUTION:A link 1 is formed on an arm body 2 and a bearing tube 3. The arm body 2 is formed on both sides of a web 4 with a pair of flanges 6 while the flanges 6 are formed on the end edges with reinforcing ribs 7 respectively. Then, hexagonal openings 8 and an equally shaped short pipe 9 are on the identical line disposed on the flanges 6 respectively. On the other hand, the bearing tube 3 has the outline formed hexagonally while having a bearing hole 11 and a calking groove 12 respectively disposed in the center and on the outer peripheries of both ends. The bearing tube 3 is inserted into the opening 8 of the short pipe 9 and pressed from above and below by metal molds so that a portion of the short pipe 9 is calked fixedly to the calking groove 12. Thus, the arm body 2 is firmly coupled with the bearing tube 3.

The present invention also relates to a link that does not require complicated press processing, and a method for manufacturing the same. In a link that connects a bushing through one end, a pair of polygonal short tubes formed by purling are provided on both flanges in a line, and a bushing with a polygonal outer periphery is inserted into the short tube. It is characterized by being caulked together.
