Webbing take-up device

A webbing take-up device comprising:

• a spool that takes up a webbing by rotating in a take-up direction, and that rotates in a pull-out direction opposite to the take-up direction by the webbing being pulled out;
• a motor that rotates a motor output shaft by driving;
• a first rotation force transmission mechanism that is capable of transmitting rotation force between the motor output shaft and the spool, and that is capable of rotating the spool in the take-up direction by being input with rotation force of the motor output shaft in a first direction;
• a second rotation force transmission mechanism that is capable of transmitting rotation force between the motor output shaft and the spool, and that is capable of rotating the spool in the take-up direction by being input with rotation force of the motor output shaft in a second direction opposite to the first direction;
• a cut-off section that cuts off transmission of rotation load along a rotation force transmission route from the second rotation force transmission mechanism to the spool via the first rotation force transmission mechanism due to the rotation load in the pull-out direction becoming a predetermined value or greater;
• and
• a resistance section that resists the rotation load during transmission of the rotation load, and that suppresses transmission of the rotation load along the rotation force transmission route in a case in which the rotation load is less than the predetermined value.
