Patent ID: 8613684

Claim:
A continuously variable transmission, comprising: first and second rotating elements that have a common first rotation axis and are arranged opposite to each other so as to be rotatable relative to each other; a rolling member that is rotatably supported by a support shaft having a second rotation axis separate from the first rotation axis, and is sandwiched between the first and second rotating elements such that torque transmission is possible between the first and second rotating elements; a transmission controlling section that changes a rotation ratio between the first and second rotating elements by tilting and rolling the rolling member; a pushing section that is a contact surface in contact with the support shaft, the pushing section is tilted at an angle to a support shaft axial direction such that axial movement of the pushing section provides a thrust force to the support shaft changing the support shaft axial direction, the support shaft extends in the first rotation axis or the second rotation axis, the thrust force is opposite in direction to a direction of tilt of the support shaft in accordance with a spin moment occurring at the rolling member; and a thrust force transmitting section that transmits, to the pushing section, the thrust force in the axial direction applied from the rolling member based on the spin moment occurring at the pushing section.
