ROTATION TRANSMISSION DEVICE AND VEHICLE USING THE SAME

摘要

A vehicle has a joint mechanism between a main frame and a front frame. The joint mechanism transmits, while permitting swing of the front frame relative to the main frame, rotational drive force produced on the main frame side to the front frame side. Also, the joint mechanism has a first joint section, a second joint section, and a joint connection body. The first joint section is rotatably installed on the main frame. The second joint section is rotatably installed on the front frame. The joint connection body is pivotally connected to the first joint section so as to form a first universal joint, and is pivotally connected to the second joint section so as to form a second universal joint.
