Abstract
There is provided a webbing take-up device including (1) a take-up shaft, (2) an attachment and detachment detection unit, (3) a motor, (4) a first transmission unit that transmits rotation of the output shaft in a first direction to the take-up shaft, (5) a second transmission unit that transmits rotation of the output shaft in a second direction to the take-up shaft, and that also transmits the output torque of the output shaft to the take-up shaft such that the take-up torque of the take-up shaft does not reach a preset first torque, and (6) a control unit that, in cases in which engagement between a tongue and a buckle has been detected, controls a drive voltage and a drive current such that the output shaft rotates in the first direction, and the take-up torque of the take-up shaft reaches a second torque higher than the first torque.
