PROBLEM TO BE SOLVED: To solve problems in laying a hydraulic hose for a boom cylinder in a conventional back hoe wherein the hose is more liable to break and unpleasing in appearance due to being exposed to the side part of a boom and moreover curved in a method of laying it in a U-turn state from the back face of the boom. SOLUTION: The boom 9 is pivotally supported to working machine mounting parts 2a projecting forward from a body frame 2 of this back hoe, through a boom bracket 8. In this constitution, the hydraulic hose H for the boom cylinder is laid to pass below a base part fulcrum of the boom cylinder 12 and above a vertical pin which is the lateral rotation fulcrum of the boom bracket 8.
