<p>A seat belt device 10 is provided with a pin 20 for connecting a spindle 12 and a tread head 14 in an initial state. The breaking load of the pin 20 is varied depending on the direction of relative rotation between the tread head 14 and the spindle, such that the pin 20 breaks at a small load through operation of a pretensioner 18. As a result, this allows firmly fixing together the spindle and the lock member during ordinary use without adversely affecting usability, and, upon vehicle collision or the like, the EA load is not affected through breaking of the pin at a small load.</p> |
