A pedestrian protecting device includes an airbag housed below a cowl louver
made
of a synthetic resin, such that it is folded in an elongated shape along the cowl
louver. The airbag can be expanded to protrude upward by an inflating gas discharged
from an inflator, to protect a pedestrian. The cowl louver includes a door portion
covering the airbag when folded and housed, and curved to protrude to the front
at the respective centers of its front and rear edges. This door portion can be
opened to the front or to the rear by the expanding airbag. The door portion is
formed integrally with the cowl louver and includes expansion promoting means so
that it can be smoothly opened.
