Abstract: An engagement structure engages a first part with a second part, and includes a receive portion provided on the first part and an insertion portion provided on the second part. The insertion portion includes an insertion main body protruded in its insertion direction to the receive portion, and protrusions protruded from a side face of the insertion main body and having elasticity to be deformable. The receive portion includes an opening provided with an opening main portion into which the insertion main body is inserted and cutouts into which the protrusions are inserted when the insertion main body is inserted into the opening main portion, and overhangs that are disposed adjacently to the opening main portion to prevent, on a back surface of the receive portion, the protrusions from being pulled out due to elastic restorations of the protrusions that have passed through the cutouts.

Abstract: A cowl cover includes a cover-body portion that covers a cowl portion between a windshield and a vehicle-body member; and a lid body to be detachably attached to the cover-body portion. The cover-body portion includes a cover-body-side engagement portion and the lid-body includes a lid-body-side engagement portion that is to be engaged with the cover-body-side engagement portion. The cover-body-side engagement portion and the lid-body-side engagement portion are configured such that an engagement amount between the cover-body-side engagement portion and the lid-body-side engagement portion increases when a load is applied from an outside to the lid-body-side engagement portion.
