For achieving the above object, its structural characteristics of the present invention are as follows, on the axletree of the rear wheel of bicycle, an end wherein is by axle, and the Campatible bracing frame of the bicycle use that slightly is the コ font that each turning of a pair of montant that can rotate freely and cross bar that is connected with the other end of montant and bottom is connected to form is installed; At least maintain certain space between any one turning and the montant, the backward directions of bicycle are provided with the outstanding lever that sole is arranged, make the swivel that is provided with in the above-mentioned space with respect to montant and lever, when bicycle when tilting with the orthogonal thereto direction of its travel direction, kiss the earth can freely rotate and support at this direction of tilt.

According to the above the present invention, when Campatible bracing frame frame being erected stop action, sole on the lever is pressed downwards as the force, turning with the Campatible bracing frame drives rear wheel as point of action, less women and the old man of strength it upwards lifted like a cork, even also can easily accomplish flexibly.

In addition, when the Campatible bracing frame erects, contact with ground, thereby can keep stable dead ship condition in the bottom of Campatible bracing frame and sole.

Further, when the bicycle that is in dead ship condition need carry out side travel, needn't firmly lift the Campatible bracing frame that maybe will be in the state of erecting to rear wheel fell, as long as make the Campatible bracing frame slightly toward lateral inclination, rear wheel is supported, swivel is contacted to earth, make its rotation, so just easily finish side travel.
