Abstract
An upright three-wheeled vehicle. A footboard part is disposed between and connected to a pair of rear wheel parts, and has a space section therein. A frame connects a front section of the footboard part to a front wheel part. A handlebar part extends upward from the frame. A suspension includes a first link perpendicularly connected to a drive shaft of a corresponding rear wheel part to initially reduce delivery of shocks by rotating and reciprocating in a lateral direction when the rear wheel part moves up and down, a second link perpendicularly bent from the first link and accommodated within the space section in a rear frame of the footboard part to secondarily reduce the shocks, and an elastic member disposed on the second link to absorb the shocks depending on a direction of the shocks applied to the rear wheel part.
