<p>PROBLEM TO BE SOLVED: To provide a rocking support element with a hollow, closed inner profile by manufacturing a rod-like shape to be formed as a hollow shape into shell-shaped open parts through injection molding, and forming the rod-like shape from one shell-shaped part formed by the close connection of the shell- shaped open parts. SOLUTION: A rod-like shape between bearing eyes 1, 2 formed at ends is manufactured from two shell-shaped parts 3, 4 which are connected together after being independently manufactured. In this case, each bearing eye 1, 2 is formed on one of the shell-shaped parts 3, 4. A cutout surrounding the bearing eye after connection is provided in the other of the shell-shaped parts 3, 4 in order to enhance stability. The shell-shaped parts 3, 4 are thus formed in mirror symmetry and are constructed as a rocking support element by opposing their open sides at the positions of mirror images, and connecting them together using appropriate connecting means.</p> |
