Abstract: The purpose of the present invention is to obtain a protective film having a segmented structure that is stable in terms of strength and that prevents the destruction or damage of a groove structure due to load deformation stress from outside and inside forces, by means of, in particular, a structure that connects a side surface of a groove to the bottom section of the groove and a structure of the bottom section of the groove.

Abstract: In a front gable portion (13) of a rubber-tired new traffic vehicle (11), an outer bumper (45) is fixed to the exterior of an inner bumper (32) constituting an underframe (33), front beams (47, 48) and side beams (49) are constructed between a roof frame (42) and the outer bumper (45), the front beams (47, 48) are inclined and curved in harmony with the streamlined design of the vehicle (11), and straight portions (47a, 48a) of predetermined lengths are formed in lower end portions of the front beams (47, 48) along a vertical direction.

Abstract: A device for improving a safety of a crew in a cab over type vehicle by absorbing shock at the time of a collision of the vehicle with a simple structure in which each main sill is provided on the right and left sides under the cab the tips of the main sills are connected together with a cross pipe in the vehicle width direction, and the cab is pivotally supported on the right and left sides of the chassis frame through the cab hinge shaft.On the other hand, the central portion of a pipe shaped like a substantial U-character, both ends of which are fixed to the right and left sides of the chassis frame respectively, rises above the chassis frame, and a belt or wire is spanned between the cross pipe and the central portion of the pipe.

Abstract: Drawing two virtual lines passing through the center of a rectangular thin plate, made of a ferromagnetic material such as a permalloy, in directions deflected 45 degrees to the right and left relative to the horizontal/vertical lines, right, left, upper and lower edge areas between the two virtual lines of the thin plate are cut out to form notches. Edges of the notches do not contact the virtual lines. A coil wire is wound utilizing bottom lines of the individual pairs of opposing notches across the center to form an excitation coil and an output coil. With this construction, coil winding can be easily achieved by a robot rather than manually. This thereby considerably reduces the production cost and provides improved product quality and measurement accuracy.

Abstract: A rear wheel steering device is provided in a vehicle with a simple structure in which rear wheels are supported at both end portions of a rear axle housing along a width direction of a chassis in order to drive the vehicle more stably at high speeds. The rear wheel steering device includes leaf spring devices connected to the chassis through first and second shackle links, respectively, and a rear wheel steering mechanism including an upper radius rod and a pair of lower radius rods, a pair of L-shaped levers, a connecting rod and a rear wheel steering actuator mounted on the chassis so that a rear wheel steering action can be smoothly and stably operated.

Abstract: A rear wheel steering device is provided in a vehicle with a simple structure in which rear wheels are supported at both end portions of a rear axle housing along a width direction of a chassis in order to drive the vehicle more stably at high speeds. The rear wheel steering device includes a leaf spring device connected to a chassis through a shackle link, a pair of upper and lower rubber pad members for sandwiching a rear axle housing and a tightening device for tightening the rear axle housing to be applied with a predetermined compressive load so that a durability of the rubber pad is improved without any frictional abrasion.
