Claims

[Scope of utility model registration request]

One end of the spool shaft, which is rotatably attached to the U-shaped housing, has multiple pawls on the outer periphery and multiple inertia plate engaging parts on the circumferential side, and is close to the inside of one side wall of the housing. an inertia plate having a flange fixed to the spool shaft, and a plurality of locking protrusions facing the flange on the circumferential side thereof and protruding from between the inertia plate retaining portions of the flange to the other side of the flange. is loosely fitted to the flange with a set spring interposed therebetween, and a cam plate is fixed that comes into contact with the back surface of the inertia plate to move the inertia plate in the axial direction toward the flange when the webbing is suddenly pulled out, and the other A plurality of lock holes are formed in the side wall of the housing facing the flange, into which the locking protrusions of the inertia plate enter and engage, and a plurality of lock holes are formed on the back side of the side wall to engage with the locking protrusions when the inertia plate moves in the axial direction. A stopper that guides the protrusion into the lock hole is fixed thereto, and an inertial body is mounted on the back side of the side wall, and a stopper that is lifted as the inertial body swings and engages with the pawl of the flange to move upward. What is claimed is: 1. A seatbelt retractor comprising a slider that is pulled up and engages with the engagement protrusion to stop the rotation of the inertia plate.
