Knuckles for pivotally supporting front wheels are supported by a knuckle support part provided at a steering arm fixed to the outer cylinder 38 so as to be turned. A first lever 56 located at a lower end part of a steering shaft 13 is connected to a second lever 58 located at an upper end part of a sub-steering shaft 57, which rotatably penetrates through the inner cylinder 37, through a connection rod 59. A third lever 62 located at a lower end part of the sub-steering shaft 57 is connected to the knuckles through tie rods. Both end parts of a rod which is not able to expand and contract are connected to a fourth lever 66, which is fixed to a rear part of the outer cylinder 38, and a vehicle body frame FA through adjustable joints. |
