In the case of arranging hydraulic hoses inside a boom, to make it possible for the hydraulic hoses to smoothly move along part of a hose introduction hole when the boom is vertically swung. On the inner surface side of the upper wall of the body part, an enlarged opening part gradually extending upward from the fore end side toward a forked side is formed, whereas on the outer surface side of the upper surface of the body part, a swelling part extending upward from the fore end side toward the forked side so as to correspond to the upper wall inner surface side, and skirt parts gradually extending downward from the lateral center of the top part of the swelling part toward the upper surfaces of the left and right leg parts are formed.
