としたものである。 To explain this with reference to the figure, auxiliary wheels 4 and
The base of a bifurcated support frame 5 that pivotally supports the frame 3 is removably screwed onto the base of the forked support frame 5, and the rear end of the front frame 7, which has a draw-type bearing portion 6 at the front end facing forward, is also removably attached to the frame 3. At the same time, the drawn bearing part 6
Inside, a drum-shaped shaft shank 11 provided on a frame 10 of an auxiliary wheel 9 having a handle 8 is fitted.

本考案は上記の如き構造としたもので、不安定
な一輪車の前部に補助輪とハンドルを設け、後部
にスタンド兼用の補助輪を設けたので、極めて安
定した状態で全くの初心者でも恐怖感なく乗車降
車も安全確実にできると共に、後部補助輪は後退
発進の練習も楽にできるものである。 This invention has the above-mentioned structure, and the unstable unicycle is equipped with a training wheel and a handle at the front, and a training wheel that also serves as a stand at the rear, making it extremely stable and even a complete beginner can feel scared. You can get in and out of the vehicle safely and reliably, and the rear auxiliary wheels make it easy to practice starting backwards.

又、前部補助輪のフレームは絞り型軸受部６に
大きく扇形揺動可能に嵌合してあるので、大きく
後傾して使用者の重心を低くくし乗車の安定をよ
くすると共に、大きく回転するのを可能にしてあ
る。 In addition, the frame of the front auxiliary wheel is fitted to the diaphragm-type bearing part 6 so that it can swing in a large fan shape, so it tilts significantly backwards to lower the user's center of gravity and improve riding stability. It has been made possible to do so.

又練習の上達度によりスタンドの役目をする二
又支持枠５と前部フレーム７を順次取外して練習
することができる。 Also, depending on the level of skill in practice, the bifurcated support frame 5 and the front frame 7, which serve as a stand, can be sequentially removed for practice.

以上の如く本願によれば乗り降りが安全確実で
安定感あり初心者に恐怖感を与えず又必要に応じ
て順次取外し高度の練習ができる効果があるもの
である。 As described above, according to the present invention, getting on and off is safe, reliable, stable, does not give beginners a sense of fear, and can be removed sequentially as necessary for advanced practice.
