A seatbelt device for a vehicle including: a belt reel having webbing wound thereon; a position detection device that detects a winding position of the belt reel; a motor that drives the belt reel to rotate to thereby perform winding of the webbing; and a control section that performs control of electric current conduction to the motor, wherein: the control section performs electric current conduction to the motor at a predetermined amount at the time of a rear vehicular collision or when a rear vehicular collision is predicted; and the electric current conduction amount is controlled, so that during electric current conduction at the predetermined electric current conduction amount, when a winding position detected by the position detection device reaches a predetermined position, variation in the winding position is suppressed.
