PROBLEM TO BE SOLVED: To provide a waterproof floor pan that secures the rigidity against deformations such as a warp and a twist that could change the size of a corner in a square in a square lattice-like reinforcing rib without increasing the thickness size of the rib and that enables the installation of leg members on the spot without these deformations being generated. SOLUTION: A first rib 13 and a second rib 14 are protrusively provided in a square lattice-like shape on a rear face 12 of the body. A plurality of boss parts 15 in which leg members are installed are protrusively provided to be connected with the boss parts 15 on a diagonal line in prescribed recesses 20 of the plurality of recesses 20 that are partitioned by the ribs. A third rib 16 is provided that divides the recesses 20 so as to make the recesses 20 appear triangular viewed from the rear face of the body. COPYRIGHT: (C)2012,JPO&INPIT |
