The invention provides a speed suppression device and a vehicle. This speed suppression device (1) is provided with: a brake drum (11); a brake shoe (23) that reduces the rotational speed of the wheel by means of a braking force generated by contact with the inner peripheral surface of the brake drum (11); an elastic member (24) that biases the brake shoe (23); an abutment member (25); a shift cam (26) that increases or decreases the force of the contact member (25) pressing the elastic member (24); and an adjustment gear (27) that adjusts the force pressing the elastic member (24) by determining the rotational position of the shift cam (26). The diameter (D1) of the shift cam (26) is larger than the diameter (D2) of the adjustment gear (27).

    本发明提供速度抑制装置和车辆。本发明的速度抑制装置(1)具备:制动鼓(11);制动蹄(23),其利用由与制动鼓(11)的内周面的接触而产生的制动力使车轮的旋转速度降低;弹性构件(24),其对制动蹄(23)施力;抵接构件(25);换挡凸轮(26),其使抵接构件(25)按压弹性构件(24)的力增减;以及调整齿轮(27),其通过确定换挡凸轮(26)的旋转位置来调整按压弹性构件(24)的力。换挡凸轮(26)的直径(D1)比调整齿轮(27)的直径(D2)大。
