Abstract
A toroidal continuously variable transmission including input and output disks rotatable about a common first axis, and power rollers interposed therebetween and supported on trunnions to rotate about a second axis. The trunnions are displaceable along a third axis extending perpendicular to the second axis and pivotally moveable about the third axis. A link connects the trunnions. A link support supports the link to allow the displacement and pivotal movement of the trunnions. A pin extending parallel to the first axis and a pin guide having an open end cooperate to support the link so as to swing about the pin and offset along the third axis. The pin is disposed on one of the link and the link support, and the pin guide is disposed on the other. Upon mounting the link to the link support, the pin is radially inserted into the pin guide through the open end.
