A vehicle seatbelt apparatus includes a inhibiting section for inhibiting a belt-reel driving motor from being driven when it determines, on the basis of an output signal from a rotational position detecting unit associated with a belt reel, that variation in the rotational position of the belt reel, which is less than or equal to a predetermined value, has occurred, on condition that a door opened/closed state detecting units detects that a vehicle door has shifted from a closed state to an opened state.
