PROBLEM TO BE SOLVED: To make a tricycle that enables a senior citizen to easily get thereon, by holding a vertical posture without being turned over even when getting thereon in the stop state, in which a vehicle body is mechanically tilted to the turning direction according to the steering of handlebars, and thereby a stable traveling is enabled on a curved road.SOLUTION: A ball joint 48 of a turning mechanism 4 moves to the left side by steering handlebars 11 to the left side. Front wheels 14L, 14R are directed to the left side, and a cam 2L mounted to a turning shaft 42L is rotated and moved forward. A right rotation pressure is applied to a turning body 3 and operated to a swing mechanism 5 and a vertical posture holding mechanism 6, and a spring 61 is bent. The upper part of side posts 41L, 41R moves to the left side, and a vehicle body 1 is tilted to the left side mechanically. A cam 2R is rotated and moved rearward without coming into contact with the other turning body 3. When the vehicle body is tilted more than required in the turning, the tilting of the vehicle body is inhibited by coming into contact with the other turning body 3, and thereby a stable traveling is made possible.

    【課題】停車状態の乗車でも転倒することなく、直立姿勢が保持でき、ハンドルの操舵に応じて旋回方向へ機械的に車体を傾斜させ、安定したカーブ走行を可能にして、高齢者が乗り易い三輪自転車にする。【解決手段】ハンドル11の左方への操舵で、転向機構4のボールジョイント48が左方に移動し、前輪14L,14Rが左方に向き、転向軸42Lに取付けられたカム2Lが前方へ回転移動し、回動体3に右回転の圧力が加わり、揺動機構5と直立姿勢保持機構6に作用して、ばね61が撓み、サイドポスト41L,41Rの上部が左方に移動し、車体1が左方に機械的に傾斜する。カム2Rは、他の回動体3に接することなく後方に回転移動し、旋回中に車体が必要以上に傾斜した場合、他の回動体3に接して車体の傾斜を抑止し、安定した走行を可能とする。【選択図】図4
