PROBLEM TO BE SOLVED: To secure riding comfort and lower a position of a driver seat.SOLUTION: A suspension device 10 includes: a link mechanism 40 that includes a caster link 42 and an under link 43 which can be oscillated vertically through a common supporting shaft 48; and an elastic member 60 that absorbs vibration of a caster wheel 31. The under link 43 includes one end part attached to a drive unit 20, the other end part 43b in a lower space of a driver seat, and a main body part 43c that bears the supporting shaft 48. The caster link 42 includes: one end part that is arranged above the one end part of the under link in a lateral space and attached to a vehicle body frame; the other end part 42b attached to a vertical shaft 32 that turns the caster wheel 31 in the lower space; a main body part 42c that bears the supporting shaft; and an erected part 42d erected in an approximately vertical direction near the one end part 42a. The elastic member 60 is attached between the one end part of the under link 43 in the lateral space and the one end part of the caster link 42.SELECTED DRAWING: Figure 2

    【課題】乗り心地を確保し、運転席の位置を下げる。【解決手段】懸架装置10は、共通の支軸48を介して上下に揺動可能なキャスタリンク42およびアンダーリンク43を含むリンク機構40と、キャスタ輪31の振動を吸収する弾性部材60とを備える。アンダーリンク43は、ドライブユニット20に取り付けられた一端部と、運転席の下方空間内の他端部43bと、支軸48を軸受する本体部43cとを含む。キャスタリンク42は、側方空間内のアンダーリンクの一端部の上方に配置されて車体フレームに取り付けられた一端部と、下方空間内のキャスタ輪31を旋回させる鉛直軸32に取り付けられた他端部42bと、支軸を軸受する本体部42cと、一端部42a側に略鉛直方向に立設された立設部42dを含む。弾性部材60は、側方空間内のアンダーリンク43の一端部とキャスタリンク42の一端部との間に取り付けられている。【選択図】図2
