ABSTRACT:
An impact-absorbing structure of a door trim mounted to a door member at an interior side of a vehicle. The door member is located at a transverse direction side portion of the vehicle. The door trim is formed with a plurality of ribs which extend from the door trim toward an exterior of the vehicle and oppose the door member. When impact load is imparted to the door member due to a side collision of the vehicle, the door member abuts the ribs which then plastically deform, thereby absorbing the impact load. Further, lengths of the ribs are such that distances between the door member and respective end portions of the ribs differ in a plurality of stages. Moreover, the plurality of ribs have respective rigidities which decrease in accordance with a decrease in the distance between the end portion of the rib and the door member.
