A powered seat sliding apparatus includes a sliding mechanism having a lower rail and an upper rail being movable in a lengthwise direction relative to the lower rail, a feed screw fixedly supported by the upper rail to be rotated around a rotational axis in the lengthwise direction in response to a rotational force of a motor, a slit train provided at both side portions of the lower rail in the lengthwise direction and being engaged with the feed screw, and a feeding mechanism defined between the feed screw and the slit train so as to slidably move the upper rail relative to the lower rail.
