The present invention relates to a device for transmitting running and turning operation force of a working vehicle. The device includes: a turning operation mechanism for controlling a turning HST to enable forward and rearward gear shifting of a vehicle; and a turning operation transmitting device for transmitting the operating force of the turning operation mechanism to the turning HST. The turning operation transmitting device has a link connecting structure composed of one or more arms and rods. Each connecting portion of the link connecting structure has a structure in which a hole and a pin are coupled to each other so as to transmit the operation force while allowing relative rotation. A turning buffer connection portion is provided in at least one connecting portion to prevent erroneous operation of the turning operation mechanism. It is possible to reduce malfunction by lowering the sensitivity of the turning operation and it is possible to improve the reliability of the turning operation.

    본 발명은 작업차의 선회 운전 조작력 전달 장치에 관한 것으로서, 선회용 HST를 제어하여 차량의 좌측 선회 및 우측 선회 변속을 가능하도록 하는 선회 조작기구와, 상기 선회 조작기구의 조작력을 상기 선회용 HST에 전달하는 선회조작 전달장치를 포함하고; 상기 선회조작 전달장치는, 하나 또는 그 이상의 암과 로드로 이루어진 링크 연결 구조를 갖고, 상기 링크 연결 구조의 각 연결부가 상대 회전이 가능하면서 조작력을 전달토록 홀과 핀이 결합된 구조로 이루어지며, 적어도 하나의 연결부에 선회 조작기구의 오조작을 방지할 수 있도록 선회용 버퍼 연결부가 구비됨으로써, 선회 운전 조작의 민감도를 저하시켜 오조작 발생을 최소화하고, 선회 운전 조작의 신뢰성을 높일 수 있는 효과를 제공한다.
