Abstract: A differential mechanism regulating device which is mechanically connected to two manipulators is miniaturized. When a first cable and a second cable are pulled, a collecting member moves its position. As a result of this movement, the collecting member tilts a portion of an arm by way of a rod. As a result, a differential lock is released. The operation of the first cable and the operation of the second cable can be merged by the collecting member, and it is sufficient to connect only a collecting transmission member to the arm. The connection between the arm and the collecting transmission member can be simplified thus realizing the miniaturization of the differential mechanism.
