Claims

[Claims for Utility Model Registration] A bending transmission part that connects a work machine to a tractor so that it can be raised and lowered via a link mechanism that has an automatic connection function, and that can be bent from the tractor to the work machine on the tractor side and the work machine side. In a work equipment attachment device that is provided with a power transmission mechanism that transmits rotational power by having a At least one of the constant velocity joints is arranged so that the inner race or outer race can be slid in the axial direction by a control lever with respect to the outer race or inner race fixed to the work equipment side or the tractor side, and in the axial direction. A work equipment mounting device for a tractor, characterized in that a locking device is provided which elastically supports the operating lever in a movable manner and can lock the operating lever when the power transmission mechanism is in a disengaged state.
