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 diskis attached to the front end of a slide screw, which is screwed with a nutdisposed within a lower railand an upper rail. A lock mechanismcomprises rollersand, springsfor imparting a force to the rollers in the peripheral direction and a supporting memberdisposed with the rollers and the springs therein. The springsimpart a force to the brake diskand the supporting memberto bring the rollersandinto a friction engagement; thus the rotation of the slide screwcan be locked. Owing to first and second engagement platesand, the rollersandare caused to roll against the force imparted by the springs, and are released from the friction engagement; thus the slide screwcan be unlocked.
