• wherein the belt airbag comprises:
• a belt-direction deployment section extendable and deployable along the shoulder belt section;
• and
• an intersecting-direction deployment section extendable and deployable in a direction intersecting the shoulder belt section,
• wherein the belt-direction deployment section and the intersecting-direction deployment section are configured to form a single bag by being coupled to each other below a head of the occupant sitting on the seat,
• wherein the belt-direction deployment section is longer than the intersecting-direction deployment section when the belt-direction deployment section extends along the shoulder belt section,
• wherein the belt-direction deployment section and the intersecting-direction deployment section form a substantially X-shape by being coupled to each other at centers thereof, and
• wherein a filler that fills a space between the belt-direction deployment section and the intersecting-direction deployment section is formed above an area where the belt-direction deployment section and the intersecting-direction deployment section are coupled to each other.
