Claims

[Claims for Utility Model Registration] (1) A webbing retractor equipped with a lock mechanism that can instantly prevent rotation of a retracting shaft in the webbing withdrawal direction in response to sudden withdrawal of the webbing, which A ratchet that rotates together with the take-up shaft, a pawl that can be engaged with and separated from the ratchet and that prevents the take-up shaft from rotating in the webbing winding direction when engaged with the ratchet, and control that engages the pawl with the ratchet when the webbing is attached. a rotational force transmission member provided between the ratchet and the winding shaft and capable of transmitting the rotation of the winding shaft to the ratchet; and when the rotational force transmission member is energized and an impact force of a predetermined value or more is applied. a buffer member that moves the rotational force transmission member to rotate the ratchet and the take-up shaft relative to each other;
A webbing take-up device comprising: (2) Utility model registration claim No. (1) characterized in that the rotational force transmitting member is a sphere and is fitted into an engaging portion formed on the ratchet so that rotation of the winding shaft can be transmitted to the ratchet. The webbing retractor described in item ). (3) Utility model registration claim No. 1, characterized in that the buffer member is a compression coil spring.
The webbing retractor described in item ).
