Resin-made floor panel structure

摘要

Rigidity distribution of trunk floor (F) is uneven, and intervals between high rigidity portions and low rigidity portions are set uneven, and more specifically a plurality of concave commodity storage spaces (E1,E2,E3,E4,E5) are integrally formed in the trunk floor, and dimensions of the these storage spaces and/or walls (Dw) formed among storage spaces are set differently from each other, so that the rigidity of the trunk floor (F) is set uneven. Thereby, in using resin materials for a floor panel, vibrations in the floor can be suppressed by a relatively simple structure without increasing the weight.
