PROBLEM TO BE SOLVED: To provide a safety tricycle having advantages of both bicycle and tricycle and improving defects thereof to solve such problems that normal bicycles are easy to sway at low-speed running, and three-wheel stationary cycles are apt to overturn when cornering at high speed.SOLUTION: There is provided a tricycle which has two front wheels; is configured so that the front wheels tilt in parallel by a parallel linkage mechanism. A parallel link and a handle are combined using an unparallel link. The tricycle can be erected even at stopping by vertical load operation applied to the handle, can be made to run without swaying at low-speed running and can be balanced well by steering at normal running even when curving with the same driving sensibility as that of a normal bicycle.SELECTED DRAWING: Figure 1

    【課題】 通常の二輪自転車は低速走行時にふらつきやすく,三輪固定式の三輪自転車は高速でカーブを切ると転倒しやすいという問題があったので,二輪車と三輪車の両方の長所を備え,短所を改善した安全な三輪自転車を提供する。【解決手段】 前輪を二輪とし,平行リンク機構により前輪が平行に傾くようにし,この平行リンクとハンドルを非平行リンクで結合し,ハンドルに加える上下荷重操作で停止時にも直立でき,低速走行時にはふらつかずに走行でき,通常走行時には普通の二輪自転車と同じ感覚でカーブでも操舵によりバランスがとれる三輪自転車を実現する。【選択図】図1
