PURPOSE:To provide a compact and lightweight constitution and securely hold the condition where no steering angle is given to the rearmost wheels. CONSTITUTION:One end of the first toggle link 25 is pivotably supported at the chip of a knuckle arm 6 which is fixed to the base end part of a knuckle supporting rearmost wheels. One end of the second toggle link 27 is pivotably supported at the other end of the first toggle link 25. The tip part of a support link 29 is pivotably supported at the other end of the second toggle link 27. The end of a position rod 35 of an air cylinder 32 is povitably supported at a connection part of the first and the second toggle links 25, 27. The first and the second togle links 25, 27 are extended by the air cylinder 32, and stretched between the knuckle arm 6 and a link stopper 36, leading to no steering angle given to the rearmost wheels. |
