摘要： A webbing winding device includes a spool, a sensor lever, and a solenoid. The sensor lever is displaceable between the first position and the second position. In a state where the sensor lever is disposed at the first position, the rotation in the drawing-out direction of the spool is enabled, and in a state where the sensor lever is disposed at the second position, the rotation in the drawing-out direction of the spool is locked. When the solenoid is actuated, a part of the sensor lever is attracted and the sensor lever is displaced from the first position to the second position. The center of gravity of the sensor lever is set so that the sensor lever is displaced toward the second position when negative acceleration with respect to the direction in which a part of the sensor lever is attracted to the solenoid is generated in the sensor lever.

摘要： A webbing winding device includes a spool, a sensor lever, a solenoid, and a controller. In a state where the sensor lever is disposed at the first position, the rotation in the drawing-out direction of the spool is enabled, and in a state where the sensor lever is disposed at the second position, the rotation in the drawing-out direction of the spool is locked. When the solenoid is actuated, a part of the sensor lever is attracted and the sensor lever is displaced from the first position to the second position. The controller adjusts the attracting force by which the solenoid attracts a part of the sensor lever. The controller adjusts the attracting force after completion of displacement to the second position of the sensor lever to an attracting force weaker than the attracting force F at the time of completion of displacement to the second position.
