To downsize a link mechanism for lifting up and down a working device while the lowest ground height of a working machine is kept high.SOLUTION: A riding working machine includes a portal rear axle case 11R having a lateral transmission case part 13 in a position higher than a shaft center of a rear wheel. There are provided in the rear part of a vehicle body frame 10, a lateral frame 10B for connecting the rear parts of a main frame 10A at a rear side from the lateral transmission case part 13, and a lower fulcrum bracket 15 extending downward from the main frame 10A in the rear side part of the lateral transmission case part 13. A top link mounting part 50 is provided above the lateral frame 10B, and a lower link mounting part 52 is provided in the lower end part of the lower fulcrum bracket 15. The lower link mounting part 52 is set in a height position equivalent to the lower edge of the lateral transmission case part 13.SELECTED DRAWING: Figure 6

    【課題】作業機の最低地上高が高い状態を維持しながら、作業装置を昇降作動させるリンク機構の小型化を図る。【解決手段】後輪の軸心よりも高い位置に横向き伝動ケース部13を備えた門形の後車軸ケース11Rを備え、車体フレーム10の後部に、横向き伝動ケース部13よりも後方側でメインフレーム10Aの後部同士を繋ぐ横向きフレーム10Bと、横向き伝動ケース部13の後方箇所においてメインフレーム10Aから下方へ向けて延出された下部支点ブラケット15と、が設けられ、横向きフレーム10B上にトップリンク取付部50が設けられ、下部支点ブラケット15の下端部にロアーリンク取付部52が設けられ、ロアーリンク取付部52は、横向き伝動ケース部13の下縁と同程度の高さ位置に設定されている。【選択図】図6
