A seat sliding apparatus for a vehicle includes a pair of lower rails for being fixed to a vehicle floor, and a pair of upper rails for being fixed to a vehicle seat each of which is slidably retained on a respective lower rail. Each upper rail includes a base plate portion for being fixed to the vehicle seat, a pair of side wall portions each of which extends from the side edges of the base plate portion in the downward direction, and a pair of engaging portions each of which is formed at the bottom edge of the side wall portion and each of which is engaged with the lower rail. A reinforcing member is also provided and is defined by at least one pair of vertical bracing walls each of which substantially intersects the space between the side wall portions of the upper rail and at least one horizontal plate connecting the top edges of the respective pairs of vertical bracing walls. The horizontal plate is fixed to the base plate portion of the upper rail such that the reinforcing member is disposed in the upper rail.
