A planetary carrier includes: a first plate and a second plate which pivotally support planetary gears between opposing plate surfaces of the first and second plates such that the planetary gears are located on a circular path so as to be spaced apart from each other, the circular path being a path of rotational centers of the planetary gears; and coupling plates which are located between the opposing plate surfaces, are spaced apart from each other in a circumferential direction of the circular path, couple the first plate and the second plate, and are coupled to external members at positions away from the planetary gears in the circumferential direction. The coupling plates are coupled to the external members at an outside of the circular path in a radial direction. Each of the coupling plates is coupled to the first plate and the second plate only at a first side in the circumferential direction.

The present disclosures relates to a toroidal continuously variable transmission which includes: a rotating shaft; a pair of outside disks supported by a rotating shaft to rotate in synchronization with the rotating shaft; an inside disk supported by the rotating shaft to rotate relative to the rotating shaft; a pair of rolling bearing units, each including a radial rolling bearing capable of supporting an axial load to support the inside disk so that relative rotation with respect to the rotating shaft is possible; a plurality of power rollers arranged between the axial inside surfaces the outside disks and the axial outside surfaces of the inside disk to transmit power between them; and a preloading mechanism elastically pressing the outer ring of the radial rolling bearing in the axial direction.

Toroidal conrtinuously variable transmission

A toroidal continuously variable transmission comprises an input disc and an output disc which are disposed to face each other; a power roller which is tiltably disposed between the input disc and the output disc and transmits a rotational driving force of the input disc to the output disc in a transmission ratio corresponding to a tilt motion angle of the power roller; a trunnion including a base on which the power roller is rotatably mounted, and a pair of side walls provided on both sides of the power roller in an axial direction of a tilt motion shaft of the power roller in such a manner that the pair of side walls extend upward from the base and face a peripheral surface of the power roller, and a beam mounted on the pair of side walls, the beam extending in the axial direction of the tilt motion shaft, on a side opposite to the base when viewed from a position of the power roller, wherein the beam includes a pair of contact portions, each of the contact portions being configured to contact an end surface of a tip end side of each of the pair of side walls, and a pair of restricting portions configured to contact side surfaces of the pair of side walls, respectively, the side surfaces facing each other, to restrict a movement of the pair of side walls in a direction in which the pair of side walls approach each other.
