PROBLEM TO BE SOLVED: To provide a method for injection-molding of a grating-like part by which it is possible to make less conspicuous a weld to be generated in the final confluence part of a molten resin and thereby upgrade the appearance quality of a grating-like injection molding when injection-molding a resin part of grating shape as well as a grating-like injection molding. SOLUTION: The method for injection-molding this grating-like part is to restrict the flow of a molten resin by thin wall parts 5a, 5b formed at a part in which odd number-th vertical bars 4a, 4c cross a horizontal bar 3 out parts in which the horizontal bar 3 crosses the vertical bars 4. Further, the resins flowing in from a part in which an adjacent even number-th vertical bar 4b crosses the horizontal bar 3 and a part in which a frame 2 crosses the horizontal bar 3 are made to join each other in the part in which the odd number-th vertical bars 4a, 4c cross the horizontal bar 3. |
