CONSTITUTION: A transferring rod connecting structure comprises a driving section(200), provided on a mould, for driving a feeder transferring section(100), and a connecting section(300) for connecting the feeder transferring sections. The driving section is provided on any one of the first and second feeder transferring sections, and no driving section is provided on the other feeder transferring section. The driving section includes a cam follower(221) mounted on a movable bracket(220) engaged to a feeder cam(211), and the feeder cam is rotated by a main shaft(210). The connecting section includes a connecting member and a bearing. A groove for accommodating the bearing is formed on an end of the transferring rod.

Abstract: 본 발명은 제 1 및 제 2 다단 스프로켓 어셈블리가 후륜의 축과 페달축에 각각 설치되고, 디레일러가 상기 후륜의 제 1 다단 스프로켓 어셈블리에 설치되고, 구동체인이 상기 제 1 및 제 2 다단 스프로켓 어셈블리사이에 감겨져서, 가속주행에 따른 원심력에 의해 상기 제 1 다단 스프로켓 어셈블리중, 가장 직경이 큰 저단의 스프로켓으로부터 가장 직경이 작은 고단의 스프로켓으로 상기 구동체인이 드레일링되어 업시프팅되거나 이와 반대로 다운시프팅되는 자동변속장치를 채용한 다단 자전거에 관한 것으로, 상기 후륜의 축과 상기 제 1 다단 스프로켓이 고정설치하는 고정수단과, 상기 페달축과 상기 제 2 다단 스프로켓 어셈블리사이에 개재된 슬립구동수단으로 구성되어, 주행중 페달을 작동하지 않더라도, 상기 후륜과 상기 제 1 다단 스프로켓 어셈블리가 상기 제 2 다단 스프로켓 어셈블리와 함께 회전하여 상기 제 1 다단 스프로켓 어셈블리중, 고단의 스프로켓으로부터 상기 저단의 스프로켓으로 상기 구동체인이 드레일링되어 다운시프팅되는 것을 특징으로 한다. 
     본 발명의 다단 자전거에 의하면, 페달링을 하지 않더라도 구동체인이 계속적으로 구동되어, 자전거의 주행속도에 따라 다운시프팅이 발생되므로, 스프로켓에 무리한 하중을 가하지 않게 되는 효과를 가진다.
