Abstract
A locking device of a seat rail for a vehicle, designed to solve problems, such as clearance or engagement error occurring in a conventional single lock member. The locking device comprises a lower rail, an upper rail coupled to the lower rail, a locking guide fixed to a bottom surface of the upper rail, a pair of lock members lifted and lowered inside the locking guide and having a plurality of locking protrusions, a plurality of locking grooves formed through a bottom surface of the lower rail so as to be engaged with the locking protrusions, and a lock spring inside the locking guide to constantly press the lock members such that the locking protrusions are engaged with the locking grooves. Even when deformation occurs on the seat rail, since all or some of the plurality of locking protrusions can be maintained in an engaged stated with the locking grooves in a manner that the locking protrusions are alternately disposed on the seat rail, engagement between the locking protrusions and the locking grooves can be safely maintained.
