PROBLEM TO BE SOLVED: To secure sufficient space occupied by an operator by comfortably enlarging a maneuvering part. SOLUTION: A retreating part which retreats backward in a slanting direction is formed in one side of the front part of a machine frame main body, and a fulcrum for mounting a boom bracket is protruded from the retreating part. An excavation work part is mounted to the fulcrum for mounting the boom bracket. It is possible for the outside line of a bucket for excavation mounted to the tip of the excavation work part to take a work form in which the outside line is approximately matched in a vertical line extended forward from the outside end of a traveling device with the maneuvering part directed forward.
