Abstract: In a normal state, a roller is engaged with an engaging projection of a rotor constituting a pretensioner and is not nipped between the rotor and a shaft. Accordingly, the shaft is freely rotated and a spool is also freely rotated so that a webbing can be pulled out and wound up. When a vehicle suddenly decelerates, the rotor is rotated and the engaging projection is separated from the roller. Accordingly, the roller is pushed by a taper of the rotor and is nipped between an outer circumferential face of the shaft and the taper. Since the rotor and the shaft are connected to each other through the roller, the rotation force of the rotor is transmitted to the shaft and the spool is rotated and the webbing is wound. Accordingly, it is possible to provide a webbing winding device in which the rotation force of the pretensioner can be transmitted to the spool without causing resistance in the rotation of the pretensioner at its operating time or wasting the rotation force for rotating the spool.
