ABSTRACT:
A wall mounting structure for a dual cavity toroidal continuously variable transmission (CVT) including two toroidal speed change units. Each toroidal speed change unit includes a pair of input and output disks rotatable about a common rotation axis, the input disks being axially spaced from each other, the output disks being disposed between the input disks and axially opposed to each other in a spaced relation, and a gear set drivingly connected with the output disks. The wall mounting structure includes a transmission case accommodating the toroidal speed change units, an intermediate wall disposed between the output disks and accommodating the gear set, and a fastener fixing the intermediate wall to the transmission case and extending in a direction perpendicular to the rotation axis of the output disks.
