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 reel comprises a hub onto which recording tape is wound and a flange that is disposed on an end portion of the hub and retains a width-direction end portion of the recording tape, wherein plural cutout portions that locally divide the hub and the flange are formed in the flange. The cross section of the hub in plan view has a substantially equilateral triangular shape and positions where constricting force resulting from the tape reaches a maximum are caused to protrude in advance.

摘要： Retention portions that retain a leader member of recording tape are formed inside a case, and a spring member pushes the leader member toward the retention portions. The spring member contacts support point members, and the support point members serve as support points when the spring member deforms. The support point members, which are disposed such that they protrude from side walls of the case, include a height D1 from an inner surface (attachment reference surface) of the side walls. The spring member is bent such that its height at positions contacting the support point members from the attachment reference surface includes a height D2 in a state where the spring member is not attached to the case. Here, D2≦D1. When the spring member is attached to the case, the spring member always contacts the support point members. Thus, the pushing force of the spring member is stable.
