Title:
自転車の定速構造
Document Type and Number:
Japanese Patent JP3146902
Kind Code:
U
Abstract:
A bicycle includes a frame, a wheel mounted on the frame, a handlebar mounted on the frame, a damping device mounted on the frame and movable to touch the wheel, a control switch mounted on the handlebar, and a connecting wire mounted on the frame and connected between the control switch and the damping device to control movement of the damping device by operation of the control switch. Thus, when the bicycle travels downhill and the rear wheel is rotated at a higher speed, the damping device provides a damping force on the rear wheel to reduce the rotation speed of the rear wheel so as to prevent the rear wheel from being rotated at an excessive high speed when traveling downhill, thereby protecting the rider's safety.
