The rocking lever for a cam mechanism presents a hollow box-type structure and consists of a modular base piece provided with the trunnions and with the cam follower rollers adapted to cooperate with the cams. The modular base piece presents two connection surfaces, arranged at 90 DEG with respect to each other, and adapted for the fastening of modular appendix pieces. The said modular appendix pieces can be secured in a removable and changeable manner to the modular base piece. |
