Claims

[Claims for Utility Model Registration] 1. A rotatable webbing winding shaft means; A locked member attached to the winding shaft means; A locking member that selectively locks the locked member. and; a control means for controlling the locking member; and an emergency state detection means connected to the control means, and the control means is configured to detect a state in which the webbing is substantially fully pulled out, a state in which a small amount of webbing is wound up, and a state in which the webbing is slightly wound up. An auto-lock state in which the locking member and the locked member are locked between a state in which a predetermined amount of webbing has been wound up from the When the state detection means detects an emergency state, it is possible to selectively set an emergency lockable state in which the locking member and the locked member are locked, and change from the auto-lock state to the emergency lockable state. The switching is performed by further winding up the webbing from the state in which the webbing has been wound up by the predetermined amount, and the switching from the emergency lockable state to the auto-locking state is performed by pulling out substantially the entire amount of webbing, and then A retractor equipped with an emergency locking mechanism and an auto-locking mechanism, characterized in that the locking is performed by winding up a small amount as described above. 2. The control means: a protrusion provided on a rotating member coaxially rotating with the webbing take-up shaft means; cooperating with the protrusion to set the auto-lock state; 2. The retractor according to claim 1, comprising: a lock arm for releasing; and biasing means having a bias force for selectively rotating the lock arm. 3. A two-stage deceleration means is provided between the webbing take-up shaft means and the control means, which reduces the rotation of the webbing take-up shaft means in two stages and transmits the transmission. Retractor as described in Section. 4. The two-stage speed reduction means is a first speed reducer provided on the webbing take-up shaft means.
a gear means; a second gear means provided on a rotating member that rotates coaxially with the webbing take-up shaft means; a third gear means meshing with the first gear means; and a second gear means. 4. The retractor according to claim 3, further comprising an intermediate gear means provided with a fourth gear means meshing with the intermediate gear means.
