    • PROBLEM TO BE SOLVED: To provide a rotational transmission member and its manufacturing method, which requires no special shaping work to prevent the part of a metal insert member joined to a resin gear from releasing and peeling. SOLUTION: The rotational transmission member includes: the shaft-shape metal insert member 12 having a first gear part 11 or 111 on the outer periphery; and a resin gear 14 formed by resin-molding on the outer periphery on one end side of the metal insert member to have a second gear part 13 or 113 on the outer periphery of the resin gear. The first gear part is formed substantially over the whole length of the metal insert member. The first gear part contains an insert part 17 on the periphery on the one end side on which the resin gear is resin molded. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供一种旋转传递构件及其制造方法,其不需要特殊的成形工作,以防止接合到树脂齿轮的金属插入构件的一部分被释放和剥离。 解决方案:旋转传递构件包括:在外周具有第一齿轮部分11或111的轴形金属插入件12; 以及通过在金属插入构件的一端侧的外周上树脂模制而形成的树脂齿轮14,以在树脂齿轮的外周上具有第二齿轮部13或113。 第一齿轮部分基本上形成在金属插入件的整个长度上。 第一齿轮部分在树脂齿轮被树脂模制的一端侧的周边上包含插入部17。 版权所有(C)2008,JPO&INPIT
