Abstract: The invention provides a ventilation member attached to a wall member having a wall opening. The ventilation member includes: an outer surface member attached to an outer surface of the wall member to cover the wall opening; and an inner surface member attached to an inner surface of the wall member to cover the wall opening and coupled to the outer surface member. The outer surface member and the inner surface member are configured as identical members and each have an opening and at least one fin provided in the opening.

Abstract: The present invention provides a utility vehicle including fuel system components located compactly. The utility vehicle includes a single or a plurality of seat rows, a cargo bed, a cabin, and an engine. The utility vehicle further includes a fuel tank accommodated in a lower space of one of the seat rows, a fuel system mounting bracket provided next to the fuel tank in the lower space and fixed to a seat frame, and a fuel feed pump and a single or a plurality of fuel system accessories mounted to the fuel system mounting bracket.

Abstract: A windscreen up-down device comprises a pair of right and left side rails disposed to extend in a forward direction and a rearward direction so as to be tilted downward in the forward direction, a center rail that is disposed between the side rails such that the center rail extends in the forward and rearward directions so as to be tilted downward in the forward direction, and a movable unit that is configured to be guided up and down along the side rails and the center rail, and is attached with a windscreen. The movable unit includes a pair of side slide members respectively guided along the side rails, a coupling member disposed to extend in a rightward direction and a leftward direction to couple the side slide members to each other, and a center slide member that is provided on the coupling member and is configured to be guided along the center rail. The side rails and the center rail have circular-arc shapes of substantially concentric circles as viewed from the side.

Abstract: A ducted fan-type tail rotor of a rotor craft in which the tail rotor is surrounded by a tubular duct is provided which includes at least six rotor blades, and pitch horns, each mounted to the respective rotor blades. Each pitch horn is swingable to change a pitch angle of the rotor blade. Some of the pitch horns, the number of which is about a half of the total number of the pitch horns, are mounted to a first type of the rotor blades at a mounting angle larger than a reference mounting angle required to obtain a predetermined thrust, and the remainder of the pitch horns are mounted to a second type of the rotor blades at a mounting angle smaller than the reference mounting angle.
