Webbing winding device

A webbing winding device comprising:

• a spool, a webbing to be attached to an occupant being wound around the spool, and the spool being rotated in a drawing-out direction by the webbing being drawn out;
• a displacement member configured to be displaced between a first position and a second position, rotation in the drawing-out direction of the spool being enabled in a state in which the displacement member is disposed at the first position, and rotation in the drawing-out direction of the spool being locked in a state in which the displacement member is disposed at the second position;
• an actuation portion, actuation of the actuation portion causing a part of the displacement member to be attracted to cause the displacement member to be displaced from the first position to the second position;
• and
• a controller configured to adjust an attracting force by which the actuation portion attracts the part of the displacement member, the controller configured to adjust the attracting force after completion of displacement to the second position of the displacement member to an attracting force that is weaker than an attracting force at a time of completion of displacement to the second position of the displacement member,
• wherein the actuation portion is configured to generate a magnetic field in response to the application of a voltage thereto, and to attract the part of the displacement member by the magnetic field, and
• wherein the controller adjusts the attracting force by which the actuation portion attracts the part of the displacement member by controlling the voltage applied to the actuation portion.
