A seatbelt winding apparatus and a seatbelt apparatus includes: a motor; and a control device configured to decrease a duty ratio of a pulse width modulation signal for controlling a driving voltage of the motor from a first value that is required to wind up a seatbelt to a second value that is smaller than the first value. After decreasing the duty ratio from the first value to the second value, the control device increases the duty ratio at an increase rate that defines an amount of increase in the duty ratio per unit time, in order to restrain the seatbelt from being pulled out.
