Webbing take-up device

The webbing take-up device includes a spool, a sensor lever, and a solenoid. The sensor lever allows rotation of the belt shaft in the pull-out direction when disposed at the first position, and locks rotation of the belt shaft in the pull-out direction when disposed at the second position. When the solenoid operates, the sensor rod is displaced from the first position to the second position. The sensor rod is provided with a hollow groove, and when a part of the sensor rod disposed at the second position is pressed toward the first position side, the hollow groove deforms to allow the displacement of the part of the sensor rod toward the first position side. 安全带卷取装置具备带轴、传感器杆以及螺线管。传感器杆在配置于第一位置的状态下允许带轴向拉出方向的旋转，在配置于第二位置的状态下锁止带轴向拉出方向的旋转。若螺线管工作，则传感器杆从第一位置向第二位置位移。在传感器杆设置有空心槽，在配置于第二位置的传感器杆的一部分被向第一位置侧按压了时，该空心槽发生变形来允许传感器杆的一部分向第一位置侧的位移。
