Abstract: A straddle-type vehicle in which a seat is arranged behind a fuel tank has improved layout flexibility behind the fuel tank is improved and allows efficient arrangement of vehicle components. The front of a fuel tank is mounted to right and left main frames via brackets. Brackets separated to the right and left are mounted to seat rails. The fuel tank has, at the rear, right and left ring-shaped brackets mounted to the brackets and an upwardly projecting recess between the right and left ring-shaped brackets. An air cleaner is disposed under the rear of the fuel tank and overlaps the fuel tank in side view.

Abstract: A straddle-type vehicle includes a rear arm connected pivotally at a front end to a vehicle body through a first connecting shaft and at a rear end to a rear wheel. A connecting member is connected pivotally at one end to the rear arm through a second connecting shaft. A link is connected pivotally to the vehicle body through a third connecting shaft and pivotally to a remaining other end of the connecting member through a fourth connecting shaft. A damper is connected pivotally at a lower end to the link through a fifth connecting shaft. A lower end of the damper is positioned below a plane A including central axes of the second connecting shaft and the fourth connecting shaft, which are positioned at both ends of the connecting member, in a fully extended state of the damper. The connecting member is curved downward to avoid interference with the damper in a fully extended state.

Abstract: The present invention presents a method and an apparatus for heat treating a metallic material by performing hydrogen absorption in or desorption from the metallic material. The method includes the steps of recovering the hydrogen gas released from a desorption step and recycling it to a hydrogen absorbing step. Hydrogen recovering can be performed either in a device containing a hydrogen absorbing alloy or in a second heat treating furnace containing the metallic material. Various controlling devices are used to regulate the process of heat treating and recovering of hydrogen gas.
