Abstract: A rear monitor camera device for a working vehicle equipped with a cable arrangement structure which is capable of preventing damage to a cable connected to a rear monitor camera installed on a counterweight and does not spoil the beauty of the counterweight. The rear monitor camera device 20 comprises a monitor camera 22 attached to the outer surface of a counterweight 14 installed on the rear part of the vehicle body, and a through-hole 26 which permits the passage of a cable 24 connected to the monitor camera 22 and is formed in the counterweight 14 from the outer surface thereof through to the inside of the vehicle body.

Abstract: This invention relates to a non-slip structure, which is highly efficient in preventing a slip with no trouble caused by a through hole, thereby enhancing reliability. The non-slip structure of this invention is characterized in that a portion of a metal plate such as a steel plate and the like is sheared so as to form cutting lines (a pair of lateral side cutting lines and a joining cutting line) for forming a protruded piece and, at the same time, the protruded piece is pulled up along the cutting lines to a height, which does not exceed the thickness portion of the steel plate so as to raise the shearing surface (edge), so that the sheared surface does not form a gap nor any through hole in contacting the steel plate.

Abstract: The invention provides a slip stopper which achieves a great slip stopping effect, and can be used for a location where a problem occurs if a through hole is opened therein. In a protruding portion that protrudes from the upper surface of a steel plate in the plate thickness direction, a concave portion and drain channels, that lead to the steel plate upper surface from the concave portion, are formed. The inner surface of the concave portion and the groove side surfaces of drain channels are formed by shear planes which extend substantially perpendicular to the steel plate upper surface, and are obtained by half blanking that does not open a through hole in the steel plate.
