第二齒輪21不旋轉。因此，經由連動軸22，僅於使 車輪9向前進方向旋轉的旋轉力被傳達的情況，第三齒輪 21向該方向旋轉’而不向相反的方向旋轉，因此，將踏板 12向相反方向踩踏的情況’亦即，即使是欲向後退的方向 旋轉的情況’其旋轉力不會傳至輪轂27,而不會阻礙前進。 如以上說明，本發明的第—實施形態的自行車的特徵 在於具備：握把1;龍頭2，其固著於握把1;前又3，其

When a rear-mounted drive wheel is attached to the rear of the ordinary bicycle, the length of the bicycle will exceed the allowable range. Therefore, the current one-wheeled bicycle of the type (4) It is a rear-wheel drive with wheels on both sides of the shelf and a separate axle under the shelf. Further, the power of the pedal is a structure in which the rear wheel is rotated by meshing the gears which are fixed to the two axles by the two divided chains. However, the problem with this tricycle is that the size and shape of the shelf or the rear structure, the limitation of the purpose of use, etc., result in various inconveniences, so that the shelf is small, and the object of use is limited to the elderly or the disabled. The adoption of these institutions will hinder the simplification of the forward agencies and lead to increased costs. The present invention is based on the considerations attached to driving a wheelbarrow to make the size and shape of the shelf and rear structure free and hairy, transported, sold, cared for the elderly, and other purposes of use. Furthermore, the simplification of the propulsion mechanism leads to lower costs. However, in the three-wheeled bicycle according to the third embodiment, the driving unicycle bicycle of the first embodiment is used, and the function of the grip operation is attached, and the two wheels are mounted on the left and right sides of the separated side, as long as they are installed. The head pipe of the driving unicycle or the frame connected to the head pipe can be used, and the degree of freedom in use of the shelf is high, and the shape and size can be set for the purpose. Further, under the shelf, etc., without the aforementioned chain mechanism, the center of gravity can be set lower, not only the shelf and the rear structure, but also the overall stability and balance of the three-wheeled bicycle can be maintained.
