を特徴としたウェビング巻取装置。This system includes a take-up shaft on which occupant restraint webbing is wound, and an inertial mass that is rotatably supported relative to the take-up shaft and rotates relative to the take-up shaft when the take-up shaft suddenly rotates to pull out the webbing. An inertia lock mechanism that operates based on the relative rotation between the inertial mass and the take-up shaft and prevents the take-up shaft from pulling out the webbing, a winding diameter sensor that detects the webbing winding diameter to the winding shaft, and this winding diameter sensor. A webbing take-up device comprising: a holding member that prevents the relative rotation of the take-up shaft and the inertial mass when the webbing take-up diameter is greater than or equal to a predetermined value when activated.
