PROBLEM TO BE SOLVED: To provide a seat rail device which restricts a slide position in a seating state and largely moves in a walk-in state without needing a large space.SOLUTION: A seat rail device 100 is used to move a vehicle seat in a fore and aft direction and includes: an upper rail 20 to which the vehicle seat is directly or indirectly attached; and a lower rail 10 for guiding the upper rail 20. The upper rail 20 includes a link member having a rotation roller provided at an inner wall surface side of the lower rail 10, biasing means which biases the rotation roller to the inner wall surface side, and releasing means which moves the biased rotation roller in a direction opposite to a biasing direction. The lower rail 10 includes a stopper member 30 having a stopper piece which is disposed at the outer side relative to the inner wall surface and contacts with the link member to restrict movement of the upper rail 20; and a rotation roller introduction piece for introducing the rotation roller from the inner wall surface.SELECTED DRAWING: Figure 1 |
