A seatbelt winding apparatus includes: a motor; and a control device configured to generate a flow of motor current in a winding-current direction that drives the motor to generate force to wind up a seatbelt, and configured to lower a current value of the motor current flowing in the winding-current direction from a first current value to a second current value, the first current value being required to wind up the seatbelt and the second current value being required to sustain tension of the seatbelt. The control device measures a current-conducting duration during which the motor current flows in the winding-current direction, and, upon the current-conducting duration having attained a set time, the control device further lowers the current value of the motor current flowing in the winding-current direction from the second current value.
