摘要： A continuously variable transmission includes a first rotating element, a second rotating element, a rolling member, a support shaft, and a support rotating element. The support rotating element includes a fixed element provided with a first guide portion guiding a first guide end portion, and a movable element provided with a second guide portion guiding a second guide end portion. The support shaft is configured such that: either one of a moving distance of the first guide end portion and a moving distance of the second guide end portion at the time when the support shaft is tilted together with the rolling member is relatively large, and the other one of the moving distances is relatively small; and an outside diameter of that one of the first guide end portion and the second guide end portion which has a relatively large moving distance is relatively larger than an outside diameter of the other one which has a relatively small moving distance. This yields such an effect that the continuously variable transmission is able to realize a smooth change gear operation.

摘要： A continuously variable transmission includes a shaft, first and second rotary members, a sun roller, a carrier, planetary balls, a gear shifter for changing a gear ratio between input and output by tilting each of the planetary balls, a casing for accommodating these elements, and a lubricating oil supply opening for supplying lubricating oil into the casing. The casing includes a discharge opening for discharging the lubricating oil to the outside of the casing. The discharge opening is provided in a wall of the casing in an axial direction of the shaft and radially outside the lubricating oil supply opening. As seen in the axial direction, the discharge opening is formed either at a position that crosses a contact section between the planetary ball and each of the first and second rotary members or an auxiliary contact section, or radially outside the contact section or the auxiliary contact section.

摘要： A stepless transmission includes: a transmission shaft; first to fourth power transmission elements; a plurality of rolling bodies clamped by the first and second power transmission elements disposed in confrontation with each other, and tiltably held by the fourth power transmission element; an axial force generator configured to generate axial force in an axial direction for pressing at least one of the first and second power transmission elements against the rolling bodies; and a transmission device configured to change a gear ratio between an input and output by tilting the rolling bodies. Young's moduli of a contact section and an additional contact section, in contact with the rolling body, of one of the first and second power transmission elements are larger than those of other one of the first and second power transmission elements.
