Claims

[Scope of utility model registration request]

A take-up shaft that is pivotally supported near both ends of the frame and that winds up the occupant restraint webbing by the urging force of the urging means, a latch gear that rotates to follow the rotation of the take-up shaft under frictional force, and is engaged with the latch gear. A separable pawl lever, a cam plate to which the rotational force of the winding shaft is transmitted via a friction means, and a drive means that senses whether the webbing is attached or not and moves the pawl lever in a direction in which it engages with the latch gear. By operating a driving means provided between the cam plate and the pawl lever, when the webbing is attached, the pawl lever can be engaged with the latch gear, and when the webbing is not attached, the pawl lever is guided in the direction of separation, and the webbing is slightly uncoiled immediately after the webbing is attached. a first guide means that engages the pawl lever with the latch gear when taken out and pulled out and blocks the webbing winding force of the take-up shaft; and a first guide means that is attached along a direction perpendicular to the axis of the take-up shaft and rotates around the axis of the take-up shaft. The latch gear includes a guide lever, a spiral groove formed in the latch gear, and a pin attached to the guide lever and inserted into the groove, and when the webbing is pulled out after the webbing is attached, the guide lever is moved along the groove by rotation of the take-up shaft. a second guide means for stopping the rotation of the take-up shaft in the webbing take-up direction by causing the guide lever to come into contact with the end of the groove when the same amount of webbing has been taken up from the webbing draw-out state as the pull-out amount; A webbing retractor having a webbing retractor.
