<p>PURPOSE:To enable steering rear wheels by providing a pair of cam plates dephased 180 deg. from each other on an input shaft turning synchronously with a steering wheel and actuating a pair of arms branched from the support point of a rear wheel support member, using said cam plates. CONSTITUTION:Cam plates 10a and 10b, symmetrical right and left, are fixed at front and rear positions of an input shaft 9, with the phase thereof shifted by 180 deg.. At symmetrical positions about the cam plate 10a, two follower levers 11a and 12a are so supported as to oscillate right and left freely and the two follower levers 11a and 12a are connected to each other with a tension spring 13a and rollers 14a and 15a on the tip of each lever 11a and 12a are so made as to be in press contact with the cam plate 10a. Also, levers 11b and 12b are supported at positions symmetrical about the cam plate 10b and rollers 14b and 15b on the tip of the levers 11b and 12b are pressed to the cam plate 10b.</p> |
