Claims

[Scope of utility model registration request]

a winding shaft that is biased and rotated to wind up the webbing;
A main ratchet wheel fixed to the winding shaft, a sub-ratchet wheel rotating together with the main ratchet wheel, a main lock bar that engages with the main ratchet wheel to prevent rotation of the winding shaft, and is engaged with the sub-ratchet wheel by a biasing means. a sub-lock bar that is biased in the direction of the take-up; a regulating member that transmits the rotation of the take-up shaft through frictional force and is rotatable through a predetermined angle and restricts the swinging of the sub-lock bar; A support member that supports the sub-lock bar and rotates in response to the rotational force of the take-up shaft via the sub-ratchet foil in response to the webbing being drawn out when the sub-lock bar and the sub-ratchet foil are engaged, and engages the main lock bar with the main ratchet foil. A webbing retractor with an automatic locking mechanism.
