PEDESTRIAN PROTECTION AIRBAG DEVICE

A pedestrian protection airbag device (10) includes an airbag case (28), a pair of inflators (32) and an airbag (42). The airbag case (28) is configured to be disposed at a lower face side of a hood rear end portion (18A) with a length direction of the airbag case (28) along a vehicle width direction. A vehicle width direction middle region (28B) of the airbag case (28) is formed with a cross-sectional height in a cross section cut up and down along the vehicle front-and-rear direction that is smaller than a cross-sectional height of a general portion (28A9 of the airbag case (28). The inflators (32) are accommodated at both of vehicle width direction ends of the middle region (28B). The airbag (42) is folded and accommodated in the airbag case (28), the airbag (42) inflating and expanding, due to pressure of gas generated by the inflators, to the vehicle rearward side through a gap between the hood rear end portion (18A) and a windshield glass (20).
