Claim:
1. A working vehicle comprising: a running vehicle capable of running; an arm installed vertically oscillatably on the running vehicle; and a supporting mechanism for vertically oscillatably supporting the arm on the running vehicle, the supporting mechanism including control links that are disposed so as to stride over the arm and the running vehicle, an arm cylinder, and a lift link, and configured to vertically oscillate the arm by expanding and contracting the arm cylinder, wherein pivotal connection points A, B, and C are provided in the running vehicle and respectively connect the running vehicle with one end part of each of the control links, with one end part of the arm cylinder, and with one end part of the lift link, with respect to a vehicle longitudinal direction, the pivotal connection point A is located on a foremost side among the pivotal connection points A, B, and C, the pivotal connection point B is located on a rear side of the pivotal connection point A, and the pivotal connection point C is located on a rear side of the pivotal connection point B, the pivotal connection point B is located below the pivotal connection points A and C with respect to a vertical direction; the pivotal connection point A is located at an intermediate part of the running vehicle in the vehicle longitudinal direction, and the pivotal connection points B and C are located adjacent to each other in a rear part of the running vehicle; and a distance between the pivotal connection point A and the pivotal connection point B is greater than a distance between the pivotal connection point B and the pivotal connection point C, and in a state in which the arm is oscillated to a lowest position,
