合を困難にする虞れがある。Prior Art and Problems to be Solved by the Invention A frame to be joined on the work equipment side is provided to be joined by superposition to the joining frame supported by the top link and the left and right lower links on the tractor side. In this type of tractor work equipment attachment/detachment device, the female spline shaft that is spline-fitted to the input spline shaft on the work equipment side that projects forward is usually provided in a refractive and transmittable shaft joint and attached to the coupling frame. Although they are rotatably supported, when making this spline connection, both of these connection frames are too large to obtain appropriate precision, so the axes of the input spline shaft and the female spline shaft must be aligned particularly in the vertical direction. It may be difficult to match and therefore make this spline connection difficult.
