PROBLEM TO BE SOLVED: To provide a bucket attachment structure of a construction machine which dispenses with a screw for operating a movable jaw, and a drive actuator such as a hydraulic cylinder, can reduce costs, and can surely prevent bucket connecting pins from coming off from a fixed jaw part and a movable jaw part, and the construction machine.SOLUTION: A fixed jaw part 1a attached to a tip of an opening arm 3a of a construction machine and a movable jaw part 1b attached to a tip of a piston 3b1 which elongates from and contracts to a bucker drive cylinder 3b, are opened at one-end sides, have semi-circular engagement parts having semi-circular shapes in cross sections corresponding to external peripheral faces of bucket connecting pins 2a, 2b, and also have semi-circular closing parts having semi-circular shapes in cross sections which support the bucket connecting pins 2a,2b between the semi-circular engagement part and themselves by blocking one-end opened sides of the semi-circular engagement parts of the fixed jaw part 1a and the movable jaw part 1b by being turned and slid after the connecting pins 2a, 2b are engaged with the semi-circular engagement parts. |
