Patent attributes
A vehicle slide rail device including: a memory mechanism which includes a memory member configured to define a default seat position by engagement; a release operation mechanism which is configured to release a lock mechanism from a locked state and slide together with the memory member in a slide direction by removing the memory member from a state of defining the default seat position; a memory operation mechanism which is configured to release the lock mechanism from the locked state while leaving the memory member in the state of defining the default seat position; a cancel mechanism which is pressed against the memory member to cancel the releasing of the lock mechanism by the memory operation mechanism and return the lock mechanism to the locked state when the seat position is returned to the default seat position defined while an operated state of a memory operation member is maintained.
