Abstract

A tricycle includes left and right front wheel support members which rotatably support left and right front wheels, respectively, and which are disposed on laterally opposite sides of a handle post and pivotally supported on left and right leg members which are supported by the handle post, a steering shaft which is connected to the front wheel support members to steer the front wheels in response to the turning operation of the steering shaft, and a driven wheel supported at a rear portion of a vehicle body frame structure. In this tricycle, a banking travel is possible, leading to an enhanced steering travelability. The handle post 21 and the left leg member 29.sub.L are connected to each other through a pair of left upper and lower links 38.sub.L, 39.sub.L to form a left parallel link arrangement 37.sub.L, while the handle post 21 and the right leg member 29.sub.R are connected to each other through a pair of right upper and lower links 38.sub.R, 39.sub.R to form a right parallel link arrangement 37.sub.R, 94.sub.R. The left and right parallel link arrangements 37.sub.L, 37.sub.R are formed laterally symmetrically with each other with respect to the handle post 21.
