Disclosed is a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation. An object of the present invention is to provide a locking device for a walk-in seat of a vehicle capable of stably maintaining the locked state of the walk-in seat prior to a walk-in operation (that is, the locked state of a drive plate for the walk-in operation of the seat) even if the engagement between the drive plate and a pawl is released due to deformation caused by a torsional load applied to a connection frame of the seat by additionally providing a separate component configured to prevent the drive plate from being rotated in an unlocking direction when a load is applied to a seat belt buckle.
