PROBLEM TO BE SOLVED: To solve a problem in a riding type traveling vehicle in which a working machine including a mounting hitch compatible with a hitch shape of a removable hitch is mounted, and further the working machine is mounted in one front place thereof when the working machine is mounted in the removable hitch, and therefore the fixing force is low and a mounting portion cannot tolerate the vibration and impact of the working machine and might be damaged.SOLUTION: A connecting device 16 is provided for connecting a riding type traveling vehicle with a walking type management machine 17 (working machine). The connecting device includes: a hitch device mounting bracket 66 (first connection part) connected to a lifting/lowering link device 11 (lifting/lowering device) of the riding type traveling vehicle a front hitch mounting hole 67 (second connection part) disposed at the rear of the hitch device mounting bracket 66, and connected to the walking type management machine 17 and a turning frame mounting bracket 69 (third connection part). The front hitch mounting hole 67 and the turning frame mounting bracket 69 are deviated and disposed in the traveling direction of the riding type traveling vehicle.SELECTED DRAWING: Figure 7COPYRIGHT: (C)2017,JPO&INPIT【課題】乗用型の走行車輌には、着脱ヒッチのヒッチ形状に対応した取付ヒッチを備えた作業機を取付けている。更に、着脱ヒッチに作業機を取付ける際には、作業機の前部の1カ所で取付けるために固定力が低く、作業機の振動や衝撃に取付け部分が耐えられず破損する場合があった。【解決手段】乗用型の走行車輌と歩行型管理機17(作業機)とを連結する連結装置16において、乗用型の走行車輌の昇降リンク装置11(昇降装置)に連結されるヒッチ装置取付金具66(第1の連結部)と、該ヒッチ装置取付金具66の後方に配置され、歩行型管理機17に連結されるフロントヒッチ取付穴67(第2の連結部)及び旋回フレーム取付金具69(第3の連結部)と、を備え、上記フロントヒッチ取付穴67及び上記旋回フレーム取付金具69は、乗用型の走行車輌の進行方向にずれて配置される。【選択図】図7
