Abstract
A webbing take-up device includes a spool, a motor that includes a rotation shaft, and an A-gear, a B-gear, a holder gear, an input gear, a clutch gear, an idle gear, and a spool gear that transmit rotation of the rotation shaft to the spool. The webbing take-up device further includes clutch weights that are moved toward a rotation-radial direction outside by being rotated together with the input gear such that rotation force of the input gear is transmitted to the clutch gear. Moreover, axial centers of rotations of the A-gear, the B-gear, the input gear and the clutch gear, and the idle gear are disposed between an axial center of rotation of the holder gear and an axial center of rotation of the spool gear.
