ABSTRACT:
An object of the invention is to provide a seat rail apparatus, which is capable of locking/unlocking forward/backward sliding of a seat for vehicle in a stepless manner with a simple structure, at an inexpensive cost. A brake disk51is attached to the front end of a slide screw5, which is screwed with a nut4disposed within a lower rail2and an upper rail3. A lock mechanism6comprises rollers63and64, springs65for imparting a force to the rollers in the peripheral direction and a supporting member61disposed with the rollers and the springs therein. The springs65impart a force to the brake disk51and the supporting member61to bring the rollers63and64into a friction engagement; thus the rotation of the slide screw5can be locked. Owing to first and second engagement plates81and82, the rollers63and64are caused to roll against the force imparted by the springs65, and are released from the friction engagement; thus the slide screw5can be unlocked.
