Patent number: 7604082Abstract: To provide a swing arm structure capable of suppressing the required rigidity of a cross member to a low level to reduce the weight of the cross member. In a swing arm structure, a swing arm includes a pair of left and right arm bodies with a cross member spanning therebetween. Ends of the swing arm suspend rear wheels. A rear wheel-driving rear drive shaft, connected to a rear final reduction gear unit, is placed above the cross member. As viewed laterally, the cross member is contained within the profile of each arm body and is formed to be trapezoidal in section such that its bottom portion is broader than its upper portion.Type: GrantFiled: September 15, 2005Date of Patent: October 20, 2009Assignee: Honda Motor Co., Ltd.Inventors: Hideo Yanai, Kozo Yamada, Yuji Maki

Patent number: 7478694Abstract: A snowmobile provided with skis and being steerable by a steering shaft, and being provided with a silencer on the front side of an engine. The steering shaft passes between the engine and the silencer and overlaps the silencer in side view. Flat step floors for a rider's feet are provided on lateral sides of a lower portion of a seat. Step bars for enabling positioning of the rider's feet are provided at front portions of the step floors. The step bars are each provided on the rear side relative to the step floor tip end and within 350 mm from a track belt drive shaft which is provided on the rear side of the engine. The resulting configuration of the snowmobile makes it possible to lay out the silencer close to the engine, affords excellent turning performance, and provides step floors for good foot holding properties.Type: GrantFiled: May 16, 2005Date of Patent: January 20, 2009Assignee: Honda Motor Co., Ltd.Inventors: Tomohisa Abe, Kozo Yamada
