To provide a tricycle that is able to prevent unstable self-support of a front frame, for example, at a low speed.SOLUTION: A tricycle 1 comprises: a frame 2; and one front wheel 92 and two rear wheels 91, supporting the frame 2 on a movement surface. The frame 2 includes: a front frame 21 on which the front wheel 92 is mounted via a front fork; a rear frame 3 on which the rear wheels 91 are mounted; and a coupling frame 32 joining the front frame 21 and the rear frame 3. The coupling frame 32 includes a shaft 33 that enables the front frame 21 to rotate around a rotary shaft 331 along forward/backward directions, in a plan view, with respect to the rear frame 3. The tricycle further comprises a resistance force generation device 8 that, when rotational force around the rotary shaft 331 is caused, applies resistance force to the rotational force.SELECTED DRAWING: Figure 1

    【課題】例えば、低速時において、前部フレームの自立が不安定になるのを抑えることができる三輪自転車を提供する。【解決手段】三輪自転車1は、フレーム2と、フレーム2を移動面上で支える一つの前輪92及び二つの後輪91と、を備える。フレーム2は、前輪92が前ホークを介して取り付けられた前部フレーム21と、後輪91が取り付けられた後部フレーム3と、前部フレーム21と後部フレーム3とをつなぐ連結フレーム32と、を有する。連結フレーム32は、後部フレーム3に対して、前部フレーム21を、平面視で前後方向に沿った回転軸331を中心に回転可能とするシャフト33を含む。回転軸331回りの回転力が生じると、回転力に対して抵抗力を加える抵抗力発生装置8を更に備える。【選択図】図1
