PURPOSE: To assume uniform and accurate toe angle control for right and left rear wheels by a device small in size and low at cost by employing a control means controlling the toe angles of the right and left wheels under the restriction of a watt link mechanism with a hydraulic chamber supplied with/emptied of working oil.
CONSTITUTION: A Watt link mechanism 30 is made up out of a center arm 32 the center of which is rotatably pivoted to the center section of a cylinder 20 by a shaft 31, and of two link arms 34L and 34R equal in length the inner end sections of which are rotatably pivoted to the both end sections of the center arm 32 by shafts 33L and 33R. And the outer end sections of the link arms 34L and 34R are rotatably pivoted to members 35L and 35R fixedly pivoted at the halfways of a right and a left output rod 22L and 22R by shafts 36L and 36R. The right and left output rods 22L and 22R are thus connected to each other by the watt link mechanism 30, the output rods 22L and 22R are thereby restricted in such a way as to be mutually moved in the opposite direction in equal moving relation in response to hydraulic pressure within a hydraulic chamber 25.
