摘要： A bearing apparatus includes a coil spring having a center portion in which a wire is wound at a predetermined pitch, and end turn portions arranged at both end portions of the center portion. Each of the end turn portions is formed by winding the wire at least three turns with a pitch which is smaller than the predetermined pitch of the center portion. A bearing member has a main body with an opening for supporting a shaft, and a connecting portion for connecting the coil spring to the main body. The main body and the connecting portion are integrally formed from a resin material by molding, and the end turn portion of the coil spring is connected to the connecting portion through molding of the main body and the connecting portion. The connecting portion of the bearing member has an inner connecting portion which protrudes into an inside of the end turn portion of the coil spring, and an outer connecting portion which surrounds an outside area of the end turn portion of the coil spring.
摘要翻译：轴承装置包括具有中心部分的螺旋弹簧，其中以预定间距缠绕线，以及设置在中心部分的两端部处的端部匝部。每个端匝部分通过以小于中心部分的预定间距的间距缠绕至少三匝来形成。轴承构件具有主体，其具有用于支撑轴的开口，以及用于将螺旋弹簧连接到主体的连接部。主体和连接部分通过模制由树脂材料一体地形成，并且螺旋弹簧的端部转弯部分通过主体和连接部分的模制而连接到连接部分。轴承部件的连接部分具有突出到螺旋弹簧的端部转弯部分的内侧的内部连接部分和围绕螺旋弹簧的端部转弯部分的外部区域的外部连接部分。

摘要： The object of the invention is to disuse press fitting of a coil spring into a bearing made of a resin material, to prevent resin chips that may be produced during press fitting. In order to achieve this object, the coil spring is inserted in the cavity of a mold. The coil spring is partly exposed in the cavity. A molten resin material is injected into the cavity and solidified. The resin material and a portion of the coil spring which is exposed in the cavity are connected to and integrated with each other.
摘要翻译：本发明的目的是不用将螺旋弹簧压配合到由树脂材料制成的轴承中，以防止在压配合期间可能产生的树脂屑。为了实现该目的，将螺旋弹簧插入模具的空腔中。螺旋弹簧部分地暴露在空腔中。将熔融树脂材料注入腔体并固化。树脂材料和暴露在空腔中的螺旋弹簧的一部分彼此连接并一体化。
