    • A stable and play-free pivot connection of a bicycle derailleur between a parallelogram link and either a base member or a chain cage. The pivot points are formed with first and second bushings that are arranged as far from one another as possible. The parts are connected by pivot pins having a anti-rotation contour for preventing rotation of the pin within an inner pivot part. The axial displacement of the pivot pin is prevented by a securing element or by a deforming element engaging a holding contour on the pivot pin. One of the first and second bushings is protected and arranged in a blind hole and the other of the first and second bushings is covered on the outside by a pin head of the pivot pin.
    • 平行四边形连杆与底座或链条架之间的自行车拨链器的稳定且无间隙的枢转连接。 枢转点形成为尽可能远离彼此布置的第一和第二衬套。 这些部件通过具有防旋转轮廓的枢轴销连接,以防止销在内枢转部分内旋转。 枢轴销的轴向位移由固定元件或与枢轴销上的保持轮廓接合的变形元件来防止。 第一和第二衬套中的一个被保护并布置在盲孔中,并且第一和第二衬套中的另一个通过枢轴销的销头在外部被覆盖。
