Abstract

A power transmission mechanism of a motorcycle includes a drive case which is disposed at the rear end of and outside of a rear swing arm, and which surrounds the axle of a rear wheel and incorporates a transmission device. In addition, the power transmission mechanism includes a drive shaft extending from an output shaft of an engine for transmitting power of the drive shaft to the rear wheel. The transmission device converts the direction of a driving force of the drive shaft and transmits it to the rear wheel. The drive shaft constituting part of the power transmission mechanism is disposed below the rear swing arm and the pivot shaft. The result is a motorcycle configuration that suppresses the vehicle width without expanding the rear swing arm.

Description

technical field [0001] The present invention relates to a two-wheeled motor vehicle equipped with a power transmission mechanism including a drive shaft that transmits driving force from an engine to rear wheels. Background technique [0002] In the prior art, a two-wheeled motor vehicle is known (for example, refer to Patent Document 1), that is, the two-wheeled motor vehicle is provided with a rear swing arm swingably mounted on a body frame via a pivot shaft, fixed on a An engine mounted on the body frame, and a power transmission mechanism including a drive shaft that transmits driving force from the engine to the rear wheels. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2002-79982 (FIG. 3) [0004] In Fig. 3 of Patent Document 1, the power transmission mechanism is provided with a tapered output shaft 106 at the rear of the power unit 21, and a drive shaft 118 is connected to the tapered output shaft 106 through a universal joint 117. The rear end of 118 ...
