Claims

[Claims for Utility Model Registration] A lock means that directly engages with the take-up shaft and prevents rotation in the direction of pulling out the webbing, and a lock means that rotates following the take-up shaft and when the rotation stops, sets the lock means to a state that prevents rotation of the take-up shaft. A locking wheel for guiding the vehicle, an acceleration detection means that is actuated by detecting an emergency state of the vehicle and stops the rotation of the locking wheel, a state that engages with the locking wheel to prevent rotation of the locking wheel, and a state in which the locking wheel is stopped from rotating. an ALR lever that is movable between a state where it is separated and allows rotation of a locking wheel; and a switching holding member that holds the ALR lever in one of the two states; By switching the ALR lever between the two states, the ELR
and ALR, the webbing retractor is pressed by the switching holding member and is movable between a first state corresponding to ELR and a second state corresponding to ALR. a lever body formed integrally with the lever body and capable of elastic deformation, which is spaced apart from the lock wheel when the lever body is in a first state, and is directly connected to the lock wheel when the lever body is in a second state; an elastic pawl that engages to prevent rotation of the locking wheel and is elastically deformed to move relative to the lever body to buffer the impact force received from the locking wheel; A webbing take-up device characterized by the following configuration.
