An airbag apparatus for pedestrian protection 18 including an airbag body 22 disposed along a vertical direction is disposed in an upper portion 16A of each of right and left front pillars 16. The expansion of the airbag body 22 toward the outer side of the vehicle is restrained to a predetermined amount by a cloth 22C connecting an attachment portion 22A of the airbag body 22 with a sewn portion 22B when the airbag body 22 is expanded. Thus, the airbag body 22 is expanded along the outer peripheral portion. In addition, a portion of the airbag body 22 expanded toward approximately the outer side in the lateral direction contacts a curved portion 30F expanded toward the inner side in the lateral direction, which is in a deployment portion 30A of a garnish panel 30. Thus, the airbag body 22 is expanded toward approximately the inner side in the lateral direction to a large extent.
