Claims

[Scope of utility model registration request]

A take-up shaft that winds up the occupant restraint webbing with a biasing force, a latch gear that rotates together with the take-up shaft, a pawl lever that can be engaged with and separated from the latch gear, and the rotational force of the take-up shaft is transmitted through friction means. a cam plate provided between the cam plate and the pawl lever, a drive means that senses whether the webbing is attached or not and moves the pawl lever in the direction of engagement with the latch gear and the direction of separation thereof; The operation when the webbing is attached makes the pole lever engageable with the latch gear, and the pawl lever is engaged with the latch gear by slightly winding and pulling out the webbing immediately after the webbing is attached, thereby blocking the webbing winding force of the winding shaft. a first guide means, a rotary cam that rotates in the same direction as the winding shaft to which the rotational force of the winding shaft is applied at a reduced speed; and a rotary cam formed on the rotary cam that separates the pawl lever from the latch gear when the webbing is pulled out after the webbing is attached. a second guide means that engages the pawl lever with the latch gear again to prevent rotation of the take-up shaft in the webbing take-up direction when the same amount of webbing as the webbing take-up amount from the webbing pull-out state has been taken up; A webbing retractor with a webbing retractor.
