PROBLEM TO BE SOLVED: To provide a motor tricycle which can enhance cornering performance by using neither a differential gear nor an active suspension.SOLUTION: A motor tricycle comprises a control part which adds an additional engine speed ratio Rd1 corresponding to a travel speed V and a steering angle θ when the travel speed V is a predetermined speed V1 or more with the steering angle θ of a predetermined angle θ1 or more with respect to an outer wheel necessary engine speed ratio R0, which is an engine speed ratio necessary for an outer wheel to an inner wheel, obtained in accordance with a handle steering angle θ detected by steering angle detection means under the assumption that no slip develops between each of right and left rear wheels and a road face when a vehicle body turns on a curve by handle turning operation, and which drives an outer wheel with drive means at an engine speed ratio R after the addition.SELECTED DRAWING: Figure 2

    【課題】ディファレンシャルギヤおよびアクティブサスペンションを用いることなくコーナリング性能を高めることができる自動三輪車を提供する。【解決手段】ハンドルの回動操作により車体がカーブを曲がる際、左右の各後輪と路面との間にスリップが生じないという仮定の下において、操舵角検出手段にて検出されたハンドルの操舵角θに応じて得られる、外輪に必要とされる、内輪に対する回転数比である外輪必要回転数比R0に対し、走行速度Vが所定速度V1以上であり、かつ、操舵角θが所定角度θ1以上であるとき、当該走行速度Vおよび操舵角θに応じた付加回転数比Rd1を付加し、その付加後の回転数比Rにて、外輪を、駆動手段にて駆動する制御部を備えている。【選択図】図2
