Gear-shifting device for vehicle

A gear-shifting device for a vehicle performing a gear-shifting operation based on a manual gear-shifting gate having a plurality of gear-shifting levels disposed one by one in a plurality of substantially straight passages vertically connected to one side or both sides along a neutral line and a diagonal passage diagonally formed from an end portion of the neutral line connected to an outermost substantially straight passage to an intermediate end of a lower substantially straight passage provided to one side of the outermost substantially straight passage, the gear-shifting device comprising:

• a guide body having a first end portion connected to a control shaft, installed so that a second end portion is rotated at the first end portion as an axis in a rotational displacement that corresponds to a selecting path to perform a selecting operation along the neutral line and the diagonal passage of the manual gear-shifting gate, and installed to be moved in a substantially straight displacement that corresponds to a shifting path along an axis direction of the first end portion to perform a shifting operation along the straight passage;
• a guide unit disposed to distinguish each shifting path on the selecting path in which the second end portion of the guide body is rotated and is configured to guide the second end portion of the guide body to be movable along the shifting path;
• and
• a stopper unit having a stopper plate rotatably disposed at an end portion position of the selecting path in which the second end portion of the guide body is rotated,
• wherein the stopper plate is configured to block the second end portion of the guide body from being positioned at the selecting path connected to an outermost substantially straight passage when the guide body rotates along the selecting path, and
• wherein when the guide body performs a shifting operation to a gear-shifting level that corresponds to a substantially lower straight passage, and is then rotated and moved toward the selecting path connected to the outermost substantially straight passage, the stopper plate is rotated to allow a gear-shifting level disposed at the outermost substantially straight passage to be shifted.
