摘要： A resin ring is integrally formed on an outer peripheral face of a metal ring to form a hub. On a lower end portion side of the resin ring, a step portion exposing the metal ring is formed. A positioning portion with which the step portion of the hub can be fitted is formed at a central portion of a lower flange. Positions in a height direction of lower end faces of the resin ring and the metal ring are different from each other. Even if a minute gap exists between the metal ring and a metal mold for molding the hub and fluid resin flows into the gap to produce a burr, the burr does not reach the lower end face of the metal ring. Therefore, variations due to the burr do not occur in the lower end face of the hub for positioning in dimension of product.
摘要翻译： 在金属环的外周面上一体地形成树脂环，形成轮毂。 在树脂环的下端部侧形成露出金属环的台阶部。 在下凸缘的中心部分处形成有能够嵌合毂的台阶部的定位部。 树脂环和金属环的下端面的高度方向的位置彼此不同。 即使在金属环和用于成型的金属模具之间存在微小间隙，轮毂和流体树脂流入间隙以产生毛刺，毛刺也不会到达金属环的下端面。 因此，在用于定位产品尺寸的毂的下端面中不会发生由于毛刺引起的变化。

摘要： A recording tape cartridge houses a reel including a hub around which recording tape is wound and at least part of which is formed by a resin. The rigidity (modulus of elasticity) y in the radial direction of the hub and the creep deformation ratio x of the recording tape satisfy the conditions of y≧87.3 exp(21.6x) and x>0.1. By setting the rigidity of the reel hub to match the creep deformation ratio of the recording tape so as to satisfy this relationship, creep deformation of the recording tape can be controlled at the smallest cost.

摘要： A reinforcement ring is insert-molded as an insert body on a reel hub of a reel around which recording tape is wound. The reinforcement ring includes a metal ring at least whose inner peripheral surface is covered by a resin layer. The clearance between the reinforcement ring and a mold during reel molding can be reduced, and the amount of eccentricity of the insert body with respect to the reel hub can be reduced.
