PROBLEM TO BE SOLVED: To increase durability and reduce the cost of a hitch. SOLUTION: The front tops of bilateral two point links 31, 31 folded in an L-shape in the side view are linked to be rotative upward and downward to the machine body of a mobile vehicle 1, a hitch 31 is linked to the rear ends of the bilateral two point links 32, 32, the folded parts of the bilateral two point links 32, 32 are mutually connected by a connection body 35 to which fitting units 37, 37 protruding forward and having connection holes 38a, 38a are constituted and the one end of a lift cylinder 35 is connected by a pin by using an actuating pin 39 passing through the connection holes 38a, 38a in the folded parts of the bilateral two point links 32, 32 and connection holes 38b, 38b of the fitting units 37, 37. Thus, the single lift cylinder 35 and the two point links 32, 32 are brought to be strong and the strength against a horizontal torsion is increased.
