ABSTRACT:
A webbing drive apparatus for an automatic seat belt apparatus in which a webbing is automatically fitted around an occupant by driving one end of the webbing which comprises a screw plate with which one end of a wire for driving the webbing is engaged and which has portions for contact with a drum so as to be rotated through the contact portions by the rotational force of the drum. It is as well as moved in the direction of the rotational axis of the drum, whereby the wire is spirally wound around the drum. Each of the contact portions have a bent portion which is bent substantially at right angles with respect to the rotational direction of the drum. The rotational force of the drum is therefore transmitted to the screw plate through these bent portions.
