PROBLEM TO BE SOLVED: To connect/disconnect an arm side connection body to/from a bucket side connection body by advancing/retracting a connection pin by operating an actuator in a state that an operator takes the driving seat of a traveling vehicle body when connecting/disconnecting a bucket. SOLUTION: The bucket side connection body is installed on the back face of a bucket and an arm side connection body is installed at the front end of a bucket arm. A coupling pin made retractably movable by an actuator is provided in the same arm side connection body, by retractably moving the coupling pin by operating the actuator from the driving section of the traveling vehicle body, the arm side connection body is made connectable/disconnectable to/from the bucket side connection body.
