Claims

[Claims for Utility Model Registration] 1. A winding shaft to which the webbing is tightly attached and rotatably supported by the retractor pace in the webbing winding direction; and a locking means formed around the winding shaft; supported by the winding shaft so as to be able to rotate in a predetermined range with respect to the winding shaft and slide in the axial direction between a position in which it engages with the locking means and a position in which it does not engage with the locking means; a latch wheel having an engaging portion for engaging with the locking means; a biasing member biasing the latch wheel toward the non-engaged position; the latch wheel being slidable in the axial direction; a ratchet wheel that is integrally attached in the rotational direction, has a gear portion, and is loosely fitted to the winding shaft so as not to be movable in the axial direction; the ratchet wheel is movable between a first position and a second position; a first ratchet lever that is movably attached and biased toward the first position; an inertial body that is loosely fitted onto the winding shaft so as to be immovable in the axial direction and operates the first ratchet lever; ; from the first position to the second position by rotating the inertial body relative to the ratchet wheel upon sensing a webbing drawing speed equal to or higher than a predetermined value)
a latch part fixed to the retractor pace that engages with the first ratchet lever brought to the retractor to stop the rotation of the ratchet wheel; a vehicle body sensing mechanism provided on the retractor pace to bring the second ratchet lever from a disengaged position to an engaged position with the gear portion of the ratchet wheel to stop rotation of the ratchet wheel; The rotation of the latch wheel is stopped, and the latch wheel slides in the axial direction without rotation against the biasing force of the biasing member, which attempts to rotate the take-up shaft in the direction of pulling out the webbing. 1. An emergency lock type retractor, characterized in that the retractor is brought into a position where it engages with a locking means, and the rotation of the take-up shaft in the webbing pull-out direction is locked. 2. The tractor according to claim 1, wherein the locking means is a through hole. 3. The retractor according to item 1 of the application for utility model registration, wherein the locking means is a recess. 4. The tractor according to claim 1, wherein the locking means 6 is a large protrusion.
