Claims

[Scope of utility model registration request]

A take-up shaft for winding up occupant restraint webbing, a first urging means for urging the take-up shaft in the webbing take-up direction with a large urging force, a latch gear pivotally supported on the take-up shaft, and the latch gear. a pawl lever that can be engaged with and separated from the pawl lever, a first guide means that engages the latch gear and the pawl lever to prevent rotation of the latch gear when the webbing is attached, a rotating plate that rotates together with the take-up shaft, and a pawl lever of the latch gear. a second biasing means for rotating the latch gear following the rotation of the rotary plate when the latch gear is not engaged with the pawl lever; a sensing lever attached to the latch gear; and the relative rotation between the latch gear and the rotary plate due to the webbing pulling rotation of the take-up shaft after the engagement of the latch gear and the pawl lever. The winding prevention means is disengaged, the sensing lever is guided and moved to the spiral groove of the rotary plate, the amount of webbing pulled out is memorized, and when the same amount of webbing has been wound from this state, the winding prevention means is re-engaged. A webbing take-up device comprising: a second guide means for preventing rotation of the take-up shaft in the webbing take-up direction.
