In a bearing structure for a front of a work machine, a box part having a rectangular cross section is formed by an upper plate, a lower plate, and left and right side plates, and a plate boss into which a connecting pin is inserted is welded to the tip of the box part. The surface of the plate boss on the box welding side is formed into a rounded surface with one radius of curvature, the upper and lower ends of the boss on the box side are equal to the thicknesses of the upper plate and the lower plate, respectively, and the tip of the side plate is The rounded portion of the side plate is formed into a radiused portion that matches the radiused surface, and the radiused portion of the side plate is welded to the radiused surface of the plate boss, and the ends of the upper plate and the lower plate are connected to the upper and lower ends of the box side of the plate boss. The front bearing structure of the working machine is characterized by welding to the front of the work machine.
