Hood lock device

When a collision load of a frontal collision imposed on a front hood is transmitted through a striker (16) from the front or the above to an upper portion of a lock device (18) provided inside a frame member (17), an upper wall (23b) of a thin-plate first member (23) of the frame member (17) to which a base portion (28) of the lock device (18) is fixed and a front wall (23a) continuous with the upper wall (23b) are deformed to allow the base portion (28) to move rearward and downward. Thereby, an impact absorption stroke for absorbing collision energy is ensured. At this time, if a rear face (28b) of the base portion (28) interferes with a rear wall (24a) of a thick-plate second member (24), the base portion (28) is hindered from moving rearward. However, the rear face (28b) of the base portion (28) passes through a first cut-out (24c) in the rear wall (24a), and thereby a rearward impact absorption stroke is ensured. Accordingly, it is possible to ensure an impact absorption stroke at collision of a front portion of an automobile by moving a front portion of a front hood at a desirable load.
