Transmission for vehicle

A transmission for a vehicle, comprising:

• a shift lever rotatable around a rotation axis, thereby allowing one of a plurality of shift stages to be selected;
• a pawl member disposed in the shift lever so as to be movable in a radial direction with respect to the rotation axis;
• a detent plate including a plurality of detent grooves formed therein and arranged along a rotational direction of the shift lever so that the pawl member is capable of being inserted into each of the plurality of detent grooves corresponding to each of the plurality of shift stages;
• and
• a shift lever actuator that rotates the shift lever to allow a shift stage to be shifted from one of the plurality of shift stages to another of the plurality of shift stages, based on a shift signal,
• wherein the shift lever actuator includes:
• a driving unit;
• and
• a driven unit that is rotated about the rotation axis by a driving force transmitted from the driving unit to cause the pawl member to move in the radial direction with respect to the rotation axis, and to apply a force to the pawl member in the rotation direction of the shift lever to rotate the shift lever,
• wherein the driven unit includes:
• a gear unit that is rotated by the driving force of the driver;
• and
• a shift guide that is rotated with the gear unit to cause the shift lever to be rotated, and
• wherein the shift guide includes:
• a first guide disposed such that a distance between the rotation axis and the first guide is equal to or greater than a distance between the rotation axis and each of the plurality of detent grooves;
• a second guide formed at one side of the first guide in a rotation direction of the shift lever, wherein the second guide is disposed such that a distance between the rotation axis and the second guide is equal to or smaller than a distance between the rotation axis and each of the plurality of detent grooves;
• a connector connected to and disposed between the first guide and the second guide;
• and
• an extension that extends from the output gear and is connected to the second guide.
