PURPOSE:To improve the operation ability of a steering wheel by setting each axis of upper and lower arms with specific relations between a top view and a side view in the suspension unit in the title, which is suspended by a double wishbone-type swing arm. CONSTITUTION:The axial area 28 of a front wheel 21 is axially supported by each pivot 24, 25 at each pointed end of an upper arm 22 and an under arm 22. And the base end area of each arm 22, 23 is fixed to a frame 27 by each supporting shaft 28, 29. In this case, each axis A, B of each supporting shaft 28, 29 is provided as follows. The axis B is provided parallel to a frame center FC as viewed from the upper side and the axis A is inclined toward a rear inside at a predetermined angle theta, so as to converge at the frame center FC from both sides. Each axis A, B is provided parallel to each other as viewed from a side, and inclined toward a front upside at the inclination theta. |
