Abstract

A swing arm structure (20) for a saddle riding electric vehicle (1) includes a swing arm (21) pivotably supported by a vehicle body frame at a pivot section (22a) and extending rearward from the pivotsection (22a) to rotatably support a rear wheel (4), an electric motor (11) that drives the rear wheel (4), and a speed reduction mechanism (12) that reduces an output of the electric motor (11) andtransmit the output to the rear wheel (4), and a housing (40) installed separately from the swing arm (21) and attached to the swing arm (21), wherein the speed reduction mechanism (12) and the housing (40) are configured as a speed reduction mechanism unit (12U) in which the speed reduction mechanism is attached to the housing and integrated with the housing.

Description

technical field [0001] The invention relates to a rocker arm structure of a saddle-riding electric vehicle. Background technique [0002] Conventionally, as a rocker structure for a saddle-riding electric vehicle, there is, for example, the rocker structure for a saddle-riding electric vehicle disclosed in Japanese Patent Application Laid-Open No. 2004-210072. The rocker arm structure of the saddle-riding electric vehicle combines the casing of the motor, the casing of the reducer, the transmission arm and the rear driving device in this order from the front to the rear. For example, the housing of the reducer is combined with the rear surface of the housing of the motor. The front end portion of the transmission arm is fixed to the housing of the speed reducer with fixing bolts. The rear end portion of the transmission arm is fixed to the housing of the rear drive device with fixing bolts. [0003] However, if the housing of the motor, the housing of the reducer, the tra...
