請求の範囲第項に記載のバツクホウ。[Scope of Claim for Utility Model Registration] A swing bracket 7 to which a backhoe device 6 is attached is mounted on the front end side of the swivel base 2, which is attached to the traveling device 1 so as to be rotatable around the vertical axis, near the left and right center. In order to switch the boom 6a of the backhoe device 6 between a first position in which the boom 6a of the backhoe device 6 is extended in front of the swivel base 2 and a second position in which it is extended laterally, the swing bracket 7 is provided so as to be swingable. The backhoe is equipped with a drive device C4 for swinging operation, and the traveling device 1 moves straight when the swivel base 2 is directed to the lateral side of the traveling device 1 and the boom 6a is viewed from above. In order to position the bucket 6c of the bucket hoe device 6 in the second posture along the direction, the rotation axis of the swivel base 2 is adjusted so that the bucket 6c of the bucket hoe device 6 is located outside the portion 9 corresponding to the straight trajectory of the traveling device 1 in plan view. The correlation among the distance l 1 between the core P 1 and the swing axis P 2 of the swing bracket 7, the width l 2 of the traveling device 1, and the width l 3 of the bucket belt 6c is l 1 > 1/2 (l 2 + l 3 ) + K (K is a constant). The backhoe according to claim 1, wherein the constant K is 5 to 15 cm.
