PROBLEM TO BE SOLVED: To facilitate connecting work of a work vehicle and an excavator by simultaneously making even a structural change in a connecting shaft come in sight by inexpensively improving rigidity by changing a shape of a guide plate luring-in part due to requiring high cost for manufacture for requiring high rigidity of a luring-in guide plate and also requiring reproducibility of positioning accuracy in setting in an applying stop positioning method using a connecting pin in a connecting fixing part of the work vehicle and the excavator. SOLUTION: A guide plate 26 of a connecting part 23 is constituted by forming a luring-in shape in a " V " shape by two fan-shaped curves. A grip 33 composed of a member bent in a " U " shape is also arranged on a rear part side surface of the connecting pin 32 in a position for revealing the positioning regulating effect of the connecting pin when the tip contacts with an insertion object member when inserting the connecting pin in the coaxial direction with the connecting pin 32.
