Continuously variable transmission for vehicle

A continuously variable transmission apparatus for a vehicle, comprising:

• a main shaft configured to receive torque of an engine;
• a subshaft disposed in parallel with and spaced apart from the main shaft;
• an output shaft disposed in parallel with and spaced apart from the subshaft;
• a reverse speed gear disposed on the main shaft without rotational interference in-between and selectively connected to the main shaft through a first clutch;
• a first speed gear disposed on the subshaft without rotational interference in-between and selectively connected to the subshaft through a second clutch;
• a second speed gear disposed on the subshaft without rotational interference in-between and selectively connected to the subshaft through a third clutch;
• a first output gear disposed on the output shaft and externally meshed with the first speed gear;
• a second output gear disposed on the output shaft and externally meshed with the second speed gear;
• and
• a variable shift apparatus continuously changing a ratio between rotation speeds of the main shaft and the subshaft so as to transmit torque of the main shaft to the subshaft,
• wherein the reverse speed gear is configured to transmit the torque of the main shaft to the subshaft through the first speed gear or the second speed gear, and
• the first output gear or the second output gear is configured to transmit torque of the output shaft to a differential through a final reduction gear.
