The present invention relates to a clutch gear for a tricycle and a step driven kick scooter. According to the present invention, power is transferred in only the forward direction of a rotary shaft, that is, a forward direction by pressing a pedal of the tricycle or the step driven kick scooter, and when moving backward, the rotary shaft, gear cover and pole make an idle rotation in a ratchet gear unit of a gear main frame. Accordingly, the present invention is able to prevent a variety of accidents which can occur when young children riding a tricycle move backward, to have a simple structure, which can be mounted on a rotary shaft by only a simple combination of a gear cover with prefabricated gear main frame, pole, and compression spring and a combination of a bearing on an external side of the gear main frame, and to be manufactured from POM materials excluding the compression spring and the bearing, thereby allowing the light weight and the mass-production of the clutch gear. According to the present invention, the clutch gear comprises a gear main frame, a bearing, a compression spring, and a gear cover.

    본 발명은 세발자전거 및 스탭 구동 킥보드용 클러치 기어에 관한 것으로서, 회전축의 전진방향 즉 세발자전거 혹은 스탭 구동 킥보드의 페달을 밟아 전진방향으로만 동력이 전달되고, 후진시에는 회전축과 기어커버, 폴이 기어본체의 래칫기어부에서 헛돌게 함으로써, 세발자전거를 타고 노는 어린아이들의 후진시 발생할 수 있는 각종 안전사고를 미염에 방지하는 효과가 있고, 기어본체, 폴과 압축스프링을 가 조립한 기어커버의 간단한 조합과 기어본체의 외측에서 베어링의 조합만으로 회전축에 장착할 수 있는 간단한 구조이면서 자체 소재는 압축스프링과 베어링을 제외한 나머지 POM 소재로 제작되어 클러치 기어의 경량화와 더불어 대량생산이 가능한 이점이 있다.
