Abstract
A vehicle pre-crash seat belt device includes: a buckle moving mechanism that moves a buckle, with which a tongue that has a webbing inserted therein engages, between a normal position and a raised position that is further toward a seat upper side than the normal position; a retractor that includes: a spool and a lock mechanism that locks rotation of the spool in the pull-out direction, and that releases the locked state by causing rotation of the spool in the take-up direction; and a controller that, due to a signal from a collision prediction sensor that predicts a collision of a vehicle, causes rotation of the spool in the take-up direction and increases tension acting on the webbing, and actuates the buckle moving mechanism to move the buckle from the normal position toward the raised position in a case in which the vehicle collision has been avoided.
