Claim:
1. A continuously variable transmission for a vehicle comprising: an input shaft receiving torque of an engine; a first power delivery shaft disposed in parallel with and apart from the input shaft; a variable shift apparatus configured to change rotation speed of the input shaft and transmit the changed rotation speed to the first power delivery shaft; a second power delivery shaft selectively receiving torque of the first power delivery shaft; a third power delivery shaft disposed apart from the second power delivery shaft; a planetary gear set including a first rotation element, a second rotation element, and a third rotation element; and an idle gear set operably connecting the input shaft with the first rotation element of the planetary gear set, wherein the second rotation element of the planetary gear set is directly connected to the third power delivery shaft and the third rotation element of the planetary gear set is directly connected to the second power delivery shaft, wherein the third power delivery shaft is coaxially disposed with the second power delivery shaft in series along an imaginary axis, wherein the planetary gear set is a single pinion planetary gear set and is configured to perform shift by torque transmitted from the idle gear set and torque selectively transmitted from the variable shift apparatus, and wherein the first rotation element of the planetary gear set is a planet carrier, the second rotation element of the planetary gear set is a sun gear, and the third rotation element of the planetary gear set is a ring gear.
