Webbing winding device

In a webbing winding device, when an external gear of a clutch receives driving force of a motor and rotates in a winding direction, a pressing portion of an inertial plate pushes a pawl and meshes the pawl with outward teeth of an adaptor. Consequently, the winding shaft rotates in the winding direction. When the external gear receives rotating force of the motor and rotates in a drawing out direction, another pushing portion of the inertial plate pushes another pawl and meshes the pawl with the outward teeth of the adapter. Consequently, the winding shaft rotates in the drawing out direction. Thus, by providing these pawls, in this webbing winding device it is possible to transmit both forward-rotation and reverse-rotation of the motor for rotating the winding shaft.
