    摘要: A straddled vehicle, including a frame structure, a rear arm, a driving wheel rotatably supported by the rear arm, a power source unit, and a drive unit including a gear box, a drive motor and a control unit. The drive motor is arranged with an off-set toward a first direction from a center of the straddled vehicle, without overlapping the power source unit in a side view. The control unit is further in a second direction than the drive motor, and overlaps the drive motor, but does not overlap the power source unit, in the side view. The gear box is further in the second direction than the drive motor, and overlaps the drive motor in the side view. The gear box is also further in the first direction than the control unit, and overlaps with the control unit, but does not overlap the power source unit, in the side view.

    摘要: An electric vehicle includes a frame unit and a vehicle body cover unit. The frame unit includes tread tubes extending toward a rear side and arranged pairwise as a left tread tube and a right tread tube. The vehicle body cover unit includes a tread board that shields the left tread tube and the right tread tube. The frame unit is provided with a battery box that receives and holds therein a battery and the frame unit is provided thereon with a side stand. The electric vehicle is provided with an electric connection mechanism on the vehicle body at one side thereof opposite to the side stand for replenishing the battery with external electric power so that a drawback that the electric vehicle tips over when replenishment of electric power is being made to the battery is prevented to thereby improve utilization of the electric vehicle.

    摘要: A final gear box accommodates a pinion gear and a bevel gear in a rotatable manner and contains an oil. A recess is provided at a downstream end of a drive shaft. The recess and the upstream end of the pinion gear shaft portion are splined coupled with each other so that the drive shaft and the pinion gear can be rotated together and relatively moved in an axial direction. A space permitting relative movement between the drive shaft and the pinion gear is provided between the pinion gear and the recess. The pinion gear is provided with a hollow portion which pierces the pinion gear in the axial direction and conducts oil to the space portion.

    摘要: An exhaust system of a saddle-ride type vehicle includes an exhaust pipe portion, a chamber portion, and a silencer. The exhaust pipe portion is coupled to an engine supported by a frame. The exhaust pipe portion is configured to guide exhaust air. The chamber portion is coupled to the exhaust pipe portion. A cross section of the chamber portion is formed larger than the exhaust pipe portion. The silencer is coupled to the chamber portion. The chamber portion includes: a main body portion disposed below the frame, and a fixing bracket projecting upward from the main body portion. The fixing bracket is secured to the frame. The frame and the fixing bracket have a fixed position. The fixed position is positioned above a lower end of the frame.
