Patent ID: 6953414

Claim:
A trunnion linkage structure for a dual-cavity toroidal continuously variable transmission, the structure comprising: trunnions each having an axis and an axial end portion; an upper link displaceable along the axis of the trunnion and formed with connection holes through which the upper link is coupled to the axial end portion of the trunnion; a stop mounted to the axial end portion of the trunnion, the stop having an outer diameter larger than each of the connection holes and limiting displacement of the upper link in an axial direction of the trunnion in which the upper link is released from the axial end portion of the trunnion; a snap ring mounted to the axial end portion of the trunnion and performing positioning of the stop in the axial direction of the trunnion; and a stop positioning portion disposed on one of the upper link and the stop and engaged with the other of the upper link and the stop so as to limit displacement of the stop in a lateral direction substantially perpendicular to the axial direction of the trunnion.
