  "textContent": "A webbing take-up device is provided with (i) a spool and (ii) a rotor rotatable integrally with the spool having a base portion and radially-extending engaging teeth. A webbing to be applied to a vehicle occupant is wound around the spool. Each engaging tooth protrudes from the base portion in a rotation axis direction of the spool, and is tapered along the rotation axis direction such that a thickness dimension in a rotation circumference direction of the spool of a portion of the engaging tooth at the opposite side thereof from the base portion becomes smaller toward the base portion side thereof. The axially-tapered shape of the engaging teeth reduces stresses and improves transmission efficiency between the rotor teeth and the teeth of a moving member engaged thereto.",
