The airbag is housed in the retainer and includes a proximal end-side folded portion folded in a roll shape or a bellows shape, an intermediate-side folded portion extending from the proximal end-side folded portion and folded above the proximal end-side folded portion, and a distal end-side folded portion extending from the intermediate-side folded portion and folded in a roll or bellows shape in a cross section in a vehicle side view. The intermediate-side folded portion has a plurality of folding-back points at which folding is made along the distal end-side folded portion in a front-rear direction of the distal end-side folded.

Abstract: This saddle-type vehicle includes an occupant protection device (21), a plurality of acceleration sensors (S1 and S2) which detect translational acceleration in a forward and backward direction acting on a vehicle, and a control device (25) which controls an operation of the occupant protection device (21) on the basis of detection values of the acceleration sensors (S1 and S2). The plurality of acceleration sensors (S1 and S2) include a first acceleration sensor (S1) and a second acceleration sensor (S2). The first acceleration sensor (S1) is disposed above a center of gravity (G) of the vehicle. The second acceleration sensor (S2) is disposed below the center of gravity (G). The control device (25) averages a detection value (de1) detected by the first acceleration sensor (S1) and a detection value (de2) detected by the second acceleration sensor (S2) and controls an operation of the occupant protection device (21) on the basis of the averaged value.
