摘要： PROBLEM TO BE SOLVED: To provide a fixation supporting system capable of establishing a good accelerating performance and a cornering performance by securing a high stiffness for precluding a sideways swing of a front fork.
SOLUTION: The system to support the fixation of the handlebar of a bicycle with its front fork is configured so that the end of the handlebar is connected with the front fork or an axle holder through a stay, whereby the load concentrated on head parts is dispersed.

摘要： PROBLEM TO BE SOLVED: To provide a reverse rotating crank enhancing a force transmission efficiency when pedaling a bicycle by reversing a rotational direction of a wheel to that of the crank.
SOLUTION: Drive chains are across each other in the vertical direction to reverse the rotation of a crank to the rotation of a driving wheel. An idle gear is provided between the crank and a gear wheel, and the gear wheel is reversely rotated to the crank. The rotational direction is changed on the driving wheel side to reversely rotate the drive chain to the wheel side gear wheel. A crank shaft and a shaft of the crank side gear wheel form two-shaft system and the rotational direction thereof is reversed by the gear. The crank side gear wheel and the wheel side gear wheel are coupled with a drive shaft, and the rotational direction is reversed.

摘要翻译：要解决的问题：提供一种通过将车轮的旋转方向反转到曲柄的旋转方向来蹬踏自行车来提高力传递效率的反向旋转曲柄。解决方案：驱动链在垂直方向上彼此相交，以将曲柄的旋转反转到驱动轮的旋转。在曲柄和齿轮之间设置空转齿轮，并且齿轮与曲柄反向旋转。在驱动轮侧改变旋转方向，将驱动链反向旋转到轮侧齿轮。曲柄轴和曲柄侧齿轮的轴形成双轴系统，其旋转方向由齿轮反转。曲柄侧齿轮和车轮侧齿轮与驱动轴联接，旋转方向相反。版权所有（C）2005，JPO＆NCIPI
