Electric motorcycle
First Claim
1. An electric motorcycle comprising:
- a power unit including a motor whose revolving shaft is oriented in a motorcycle width direction and a centrifugal clutch configured to transmit a rotary drive force of the motor to an output shaft, said output shaft being provided in parallel to the revolving shaft, whereinthe centrifugal clutch is coaxially arranged with the motor, and includes a primary driven gear arranged coaxially with the output shaft and configured to transmit a drive force transmitted from the centrifugal clutch to the output shaft,the primary driven gear is disposed so as to be interposed between the centrifugal clutch and the motor in an axial direction of the revolving shaft; and
,wherein the primary driven gear is arranged so as to overlap with the centrifugal clutch in a side view of the motorcycle so that an outline thereof comes close to the revolving shaft.

Abstract
In a electric motorcycle including a power unit having a motor whose revolving shaft is oriented in the vehicle width direction, and a centrifugal clutch configured to transmit a rotary drive force of the motor to an output shaft, the centrifugal clutch is arrange coaxially with the motor. A primary driven gear arranged coaxially with the output shaft and configured to transmit a drive force transmitted from the centrifugal clutch to the output shaft is provided. The primary driven gear is arranged so as to be interposed between the centrifugal clutch and the motor in the axial direction of the revolving shaft. A clutch outer is fixed to a clutch outer holder which is relatively rotatable with respect to the revolving shaft, and the primary driven gear is engaged with a primary drive gear formed on the outer periphery of the clutch outer holder.
