PURPOSE:To raise trailing traveling performance at high speed by connecting the rear part of a car with the front part of a trailer by means of a pair of left and right links and making a distance between the front ends larger than that between the rear ends of the link and further bringing the center of instantaneous rotation of the trailer close to the axled direction of the trailer. CONSTITUTION:A wide hitch plate 11, long in left and right directions, is provided fixedly to the rear part of a car 1 towards the rear. On the other hand, a hitch plate 12, long in left and right directions, is also provided fixedly to the front part of a trailer 2 towards the front. Then, front end parts 13a, 14a of a pair of links 13, 14, equal in length with each other, are attached to both left and right end parts 11a of the hitch plate 11 by means of perpendicular shafts 15, 16 respectively, while the rear end parts 13b, 14b of the links 13, 14 are attached to both left and right end parts 12a of the hitch plate 12 by means of perpendicular shafts 17, 18 respectively. Thus, a stand-shaped link, as a whole, is formed. Further, after setting a distance between the front end perpendicular shafts 15, 16 larger than that between the rear end perpendicular shafts 17, 18 a point P1, at which the central line of the link 13 intersects that of the link 14, is brought in correspondence with an axis on an axle 3 of the trailer 2. |
