  • Patent number: 7431112
    Abstract: A hybrid motorcycle capable of mounting thereon a hybrid-type drive unit, which does not project in a vehicle width direction and can be mounted even on a motorcycle having a limited vehicle width, includes a power distributing device positioned between a generator and a motor, and a reduction device arranged rearwardly of the power distributing device. A front end of a drive-wheel transmission device is journaled on a rear end of a central storage casing so that a rear end side of the drive-wheel transmission device is vertically swingable, and a rear wheel is journaled on the rear end of the drive-wheel transmission device. The power distributing device includes a sun gear, planetary gears, a planetary carrier, and a ring gear. Further, a carrier shaft projects from a rotor shaft and rotation of a crank shaft is transmitted through a intermediate gear portion to the projecting end of the carrier shaft.

  • Patent number: 7182167
    Abstract: A hybrid-type unit for a two-wheeled vehicle can include an engine, a motor for driving a wheel of a vehicle, a power distribution mechanism, and a generator. The generator and the motor can be disposed at different positions offset longitudinally from each other and offset from the power output shaft of the engine.

  • Patent number: 4978181
    Abstract: A sunshade composed of a transparent substrate, a first base and a second base which are provided on the both surfaces of the substrate, an infrared ray-reflecting layer which is provided on the first base and which reflects infrared rays, and a sun light-reflecting layer which is provided on the second base and which reflects a sun radiant energy with partly transmitting visible rays. The infrared ray-reflecting layer may optionally be coated with a protective layer. At least one of the protective layer, the first base and the second base has a rough surface which may diffusively reflect the light as reflected by the infrared ray-reflecting layer and the sun light-reflecting layer. In place of formation of the rough surface, a light-diffusing agent may be incorporated into the substrate, the both bases or the protective layer.
