An all-terrain vehicle has a chassis based on two longitudinal box section members and designed to permit a degree of torsional flexibility, with four beam axles equally spaced along the wheelbase. The drive transmission is arranged so that drive to the wheels on all four axles, or only the center two, can be selected, and the wheels on both the front and rear axles are steerable. The front axle wheels are positively steered whereas the rear axle wheels are arranged to castor to a smaller turnin...

This invention is generally a longitudinally slit tubular molding member that can be opened up or closed so as to receive electric wires extending therethrough, and comprising a base mountable on a wall and a pivotable cover to enclose the wires, and including hooks for attaching the wires inside the molding member.

An all-wheel-steerable vehicle has two front wheels, two rear wheels, and a steering system for steering the front and rear wheels in interlinked relation. The front and rear wheels are steered in the opposite directions to each other, and the steering angle of the front wheels is greater than the steering angle of the rear wheels. The vehicle thereby gives the driver a favorable drive feeling while obtaining a small radius of turning movement of the vehicle.
