Claims

[Scope of utility model registration request]

A take-up shaft for winding up occupant restraint webbing, a latch gear that rotates together with the take-up shaft, a pawl lever that can engage and separate from the latch gear, and a cam plate to which the rotational force of the take-up shaft is transmitted via friction means. a drive means that senses whether the webbing is attached or not and moves the pole lever in the direction of engagement with the latch gear; and a drive means provided between the cam plate and the pawl lever that moves the pole lever when the webbing is attached. The pole lever can be engaged with the latch gear and guides the webbing away when it is not attached, and when the webbing is slightly wound up and pulled out immediately after the webbing is attached, the pole lever is engaged with the latch gear and the webbing winding force of the winding shaft is prevented. 1 a guide means, an internal gear wheel to which rotational force of the winding shaft is applied when the drive means is activated, and a pawl lever formed on the internal gear wheel to separate the pawl lever from the latch gear when pulling out the webbing after the webbing has been attached, and to remove the webbing from the pulled-out state. a second guide means for engaging a pawl lever with a latch gear to prevent rotation of a take-up shaft in a webbing take-up direction when the same amount of webbing as the pull-out amount has been taken up.
