PROBLEM TO BE SOLVED: To provide an intake system resin component capable of preferably improving impact resistance of an upper outer wall.SOLUTION: An upper outer wall 14 of an air cleaner box 12 positioned at a vertical upper part of an air cleaner when the air cleaner is installed at an engine room is set to have a shape in which a plurality of convexoconcave patterns 15 formed in such a way that its planar shape forms a hexagon and a portion corresponding to a planar central part of the hexagon may expand to an outside part of the air cleaner in respect to a portion corresponding to each side of the hexagon are arranged adjacent to each other. Further, all the portions in arrangements of the convexoconcave patterns 15 do not produce any location where the boundary lines of the convexoconcave patterns 15 are continuously connected to each other on the same straight line.SELECTED DRAWING: Figure 2 |
