Abstract
To provide a swing arm structure capable of suppressing the required rigidity of a cross member to a low level to reduce the weight of the cross member. In a swing arm structure, a swing arm includes a pair of left and right arm bodies with a cross member spanning therebetween. Ends of the swing arm suspend rear wheels. A rear wheel-driving rear drive shaft, connected to a rear final reduction gear unit, is placed above the cross member. As viewed laterally, the cross member is contained within the profile of each arm body and is formed to be trapezoidal in section such that its bottom portion is broader than its upper portion.

A swing arm structure wherein a swing arm includes a pair of left and right arm bodies and a cross member for spanning therebetween, an end of the swing arm suspends rear wheels, and a rear wheel-driving rear drive shaft operatively connected to a rear final reduction gear unit is placed above the cross member,
- wherein, as viewed laterally, the cross member is contained within a profile of each arm body, and is formed to be trapezoidal in section such that a bottom portion thereof is broader than an upper portion thereof.
A swing arm structure comprising:
- a swing arm having a pair of left and right arm bodies, said left and right arm bodies having a profile with a predetermined height;
- a cross member for spanning between the pair of left and right arm bodies;
- an end of the swing arm being adapted for suspending rear wheels;
- and
- a rear wheel-driving rear drive shaft operatively connected to a rear final reduction gear unit, said rear wheel-driving rear drive shaft being positioned above the cross member,
