Abstract: A coupling structure includes a first coupling portion formed by one end portion of a first tube, and a second coupling portion formed by one end portion of a second tube, and is configured such that the first coupling portion is inserted in the second coupling portion, the first coupling portion and the second coupling portion are coupled, with the second tube being pivotable with respect to the first tube, and a gap is formed between an outer surface of the first coupling portion and an inner surface of the second coupling portion in a first state in which a fluid is not flowing through the flow path, and in a second state in which the fluid is flowing through the flow path, pressure of the fluid causes the first coupling portion to deform to expand toward an outer side of the flow path to reduce the gap.

Abstract: The airbag device protects the occupant seated in the vehicle seat disposed in the vehicle. An airbag device includes a first airbag group and a second airbag group that are disposed in the vehicle seat in correspondence with impacts from two different directions and that respectively include a plurality of airbags; a gas generation unit that is disposed in a seat cushion, of the vehicle seat, that supports the buttocks region of the occupant and that generates gas to be supplied to the first airbag group or the second airbag group; and a switching unit that switches the supply of gas to either the first airbag group or the second airbag group.
