Claims

[Scope of utility model registration request]

A lock arm keeper 10 that rotates together with the webbing take-up shaft 6 of the retractor, and a lock arm keeper 10 that is rotatably supported relative to the take-up shaft 6 and rotatable within a predetermined range relative to the lock arm keeper 10. The main body portion 14 is slidably supported on the inertia mass 18 at a position close to the rotation axis of the inertia mass 18, and a branch portion 15 protruding from the center of the main body portion 14 is attached to the inertia mass 18. is pivotably supported by the lock arm keeper 10 at a position close to the outer periphery of the main body portion 14, and when the lock arm keeper 10 rotates in the direction of pulling out the webbing with respect to the inertia mass 18, a claw 16 formed at one end of the main body portion 14 moves the inertia mass 18. A lock arm 13 protruding from the outer periphery, and the lock arm 1
3 against the lock arm keeper 10 in the direction of rotation when the webbing is drawn out;
0, and a clutch 2 rotatably supported with respect to the winding shaft 6 and having internal teeth 22 that engage with the pawl 16 of the lock arm 13 when the lock arm 13 is extended.
1, and locking means 28 and 7 for stopping the rotation of the winding shaft 6 when the clutch 21 rotates in the direction of pulling out the webbing,
The pawl 16 of the lock arm 13 and the clutch 2
An emergency locking mechanism for a retractor, characterized in that engagement surfaces 24 and 25 with the internal teeth 22 of the lock arm 13 are inclined in a direction in which the lock arm 13 is disengaged from the inertia mass 18 with respect to the sliding direction of the lock arm 13 with respect to the inertia mass 18.
