Abstract:
1. A seat sliding apparatus for a vehicle, comprising: a lower rail secured to a stationary portion of the vehicle; an upper rail fixedly attached to a seat of the vehicle and assembled to the lower rail to be movable in a front-rear direction of the seat, the upper rail being movable between an insertion position and a finally assembled position in a vertical direction within a space defined between the upper rail and the lower rail; restraining means for restraining a sliding movement of the upper rail over a predetermined moving amount in the front-rear direction of the seat, the restraining means including a first projection extending in a lateral direction from a downardly-depending wall of the upper rail and second projections extending in a vertical direction from a downwardly-depending wall of the lower rail, the lower rail and the upper rail being structured in a way that an interval between the first projection and each second projection along the vertical direction in which the upper rail moves between the insertion position and the finally assembled position is greater than zero, and the restraining means restraining the sliding movement of the upper rail over the predetermined moving amount by a contact between the first projection and each second projection; and a slide supporting member disposed between the upper rail and the lower rail, the slide supporting member supporting the upper rail to be slidable in the front-rear direction relative to the lower rail and positioning the upper rail to the finally assembled position in the vertical direction.
