A power seat sliding apparatus does not produce an unusual sound and a good operation feeling is obtained. The power seat sliding apparatus includes a first load transmission member fixedly attached to an upper rail and having a first surface that intersects with an axis of a threaded rod and a second surface that opposes the first surface with a space in between, and a second load transmission member installed in the space between the first surface and the second surface, fixedly attached to the threaded rod, and having a third surface on which to abut the first surface and a fourth surface on which to abut the second surface. The first surface and the second surface are concave curved surfaces and the third surface and the fourth surface are convex curved surfaces.
