PROBLEM TO BE SOLVED: To accurtely press-form rack teeth on a formed side while securing rigidity of the rack teeth, the formed side being one of two or more formed sides formed by bending a metal plate and being positioned at an end, even when the metal plate is a hard and thin material.SOLUTION: There is provided a parts 31 with integrally-formed rack teeth in which at least two or more formed sides 41-46 formed by bending perform prescribed functions, and the rack teeth 33 are integrally press-formed in a straight line on at least one of the formed sides 41, 46 positioned at the ends of a metal plate-made parts. In the parts 31 with integrally-formed rack teeth, the rack teeth 33 are formed in such a manner that a flat plate-shaped flange 35 is provided along the rack teeth 33 on the edge 51b of the metal plate on the formed side 46 on which the rack teeth are press-formed.COPYRIGHT: (C)2013,JPO&INPIT【課題】金属板が硬く薄い材料であっても、金属板を曲げ加工して形成される2以上の形成面のうち端に位置する形成面において、剛性を確保しながら精度良くラック歯をプレス成形する。【解決手段】折り曲げられて形成される少なくとも2以上の形成面41~46が所定の機能を果たす金属板製部品の端に位置する形成面41,46のうち少なくとも一方に、プレス成形によりラック歯33が直線状に一体形成されており、該ラック歯がプレス成形される形成面46における金属板の縁端51bにラック歯33に沿って平板状のフランジ部35が設けられてラック歯33が形成されていることを特徴とするラック歯を一体形成した部品31。【選択図】図3
