摘要： Construction is achieved whereby durability is maintained while size and weight are reduced. Installation plate sections are provided on the top and bottom end sections of a pair of support columns. Bolts are inserted through through-holes that penetrate through the installation plate sections in the axial direction; the bolts are then screwed into screw holes provided in the axial direction of anchor sections of an actuator body and a connecting plate, and the bolts are further tightened, whereby the support columns are securely joined and fastened to the actuator body and the connecting plate.

摘要： A toroidal continuously variable transmission includes a preload spring disposed between a rotary assembly including a first disc and a pressing device, and a driving force transmission shaft, and a thrust bearing disposed between a first member and the preload spring, the first member being one of the rotary assembly and the driving force transmission shaft. In a direction of an axis line, a gap is formed between a second member and the thrust bearing, the second member being the other of the rotary assembly and the driving force transmission shaft. A dimension of the gap in the direction of the axis line is less than a deformation amount of the preload spring in the direction of the axis line, at an elastic limit.
