A power seat driving apparatus for a vehicle includes a moving unit and a decelerating mechanism (3) which includes a driving gear (51), a driven gear (52) engaging with the driving gear (51) and driven to rotate while decelerating a rotational speed of the driving gear (51), a supplemental gear (53) coaxially connected to the driven gear (52) in an interlocking manner, made of a resin material having elasticity and lower rigidity than the driven gear (52), having a larger tooth thickness than a tooth thickness of the driven gear (52) by an amount corresponding to a backlash, and engaging the driving gear (51) together with the driven gear (52), and a housing (6) accommodating and rotatably supporting the driving gear (51), the driven gear (52) and the supplemental gear (53). |
