A seat slide device for adjusting the forward and backward positions of the seat which comprises an upper rail and a lower rail, the upper rail being slidably fitted to the lower rail, in which a seat belt is at its one end secured to one of the upper rail and seat. In one of the upper and lower rails, formed are a plurality of projected pieces, while in the other of those rails, formed are a plurality of incised portions, so that, when an upward pulling force is exerted upon the upper rail via the seat belt, the projected pieces are pressed against the incised portions to bend them and pass therethrough, thereby causing a mutual direct engagement of the upper and lower rails to prevent removal of the upper rail from the lower rail. |
