<p>Provided is a seat belt device wherein movement of a webbing from the shoulder side toward the lap side can be prevented or restrained when the webbing is pulled, without particularly increasing the strength of the webbing. A dilatant characteristic part (62) configured so as to include a dilatant characteristic resin member (66) is provided in a webbing (18) from a lap webbing (42) portion to a portion that extends further to the shoulder webbing (44) side than the through-hole (24) of a tongue (22) in a webbing-attached state. When the webbing (18) is pressed against an inner peripheral part of the through-hole (24) due to a vehicle occupant's body pulling the webbing (18) when the vehicle rapidly decelerates, the dilatant characteristic resin member (66) is hardened by the load. The flexure of the webbing (18) when the webbing (18) attempts to move through the through-hole (24) is thereby restricted, and the shoulder webbing (44) can therefore be prevented or restrained from moving through the through-hole (24) to the waist of the vehicle occupant.</p> |
