Abstract
A webbing take-up device includes a spool that takes up webbing worn by an occupant, an input gear that is rotated by rotation force being transmitted, a spool gear that rotates the spool by being rotated, and a second clutch that is provided between the input gear and the spool gear, and that transmits rotation force of the input gear to the spool gear by being rotated by the input gear. The webbing take-up device further includes a sub clutch spring that is provided between the input gear and the second clutch, that transmits rotation force of the input gear to the second clutch when the input gear is rotated toward one side, and that shuts off transmission of rotation force of the input gear to the second clutch when the input gear is rotated toward another side.
