In a seatbelt device, at a time of an emergency of a vehicle, gas is supplied into a tube, and gas within the tube is supplied into a chest bag of a bag, and the chest bag is inflated and expanded. Here, at a time when gas is supplied into the tube, due to the tube being inflated between a webbing and a lower side peripheral surface of an insert-through hole of a tongue, a transverse direction other side portion of the bag is crushed by the tube, and gas that is within the chest bag passing via the transverse direction other side portion of the bag into a waist bag of the bag is limited. Therefore, the chest bag can be inflated and expanded at an early stage.
