A special-shaped riveting pin for a stepless speed change clutch includes a transmission plate and actuating blocks, which are firmly combined together by the special-shaped riveting pin. The transmission plate is bored with a non-round riveting hole while the special-shaped riveting pin is formed with a non-round riveting portion to be correspondingly riveted with the non-round riveting hole. Thus, the actuating blocks and the transmission plate can firmly combined together for reinforcing the riveting pin so that the stepless speed change clutch can be used for a vehicle engine that outputs comparatively large torsion.
