A resin cover includes an insertion strip configured to be inserted into an insertion hole formed in an object member, and a clip configured to be fitted into an attachment hole formed in the object member. The clip is arranged and constructed to be fitted into the attachment hole of the object member while the insertion strip is inserted into the insertion hole of the object member. The insertion strip has a first rib formed therein and positioned adjacent thereto. The first rib is configured to interfere with the object member when the insertion strip is displaced laterally with respect to the insertion hole during an insertion operation of the insertion strip into the insertion hole, so as to displace the clip substantially upward or downward with respect to the attachment hole.
