Abstract
In a tricycle in which left and right front forks (30L, 30R) for rotatably supporting left and right front wheels (WFL, WFR) respectively are disposed on laterally opposite sides of a handle post (21) to extend upwards and downwards and are turnably carried on left and right side posts (29L, 29R) supported on the handle post (21), and an upper link (35U) connected at its opposite ends to the left and right side posts (29L, 29R) and a lower link (35D) connected at its opposite ends to the left and right side posts (29L, 29R) are turnably connected at their central portions to the handle post (21), the left and right side posts (29L, 29R) are disposed in an inclined state, so that the distance between both of the side posts (29L, 29R) is decreased toward their upper portions. Thus, the tricycle can be braced sufficiently by inner one of the front wheels during bank-traveling thereof.
