ることができず、非常に不便であった。(Problems to be solved by the invention) Therefore, conventionally, when a unicycle is displayed and displayed at a store,
Since it was necessary to provide a stand separate from the unicycle, the display and exhibition of the unicycle was very troublesome. In addition, when the unicycle is stored after being used by children, the unicycle is installed sideways, and the unicycle cannot be compactly stored and stored, which is very inconvenient.
本発明は上記問題点に鑑み、一輪車を簡単に起立状態
で設置できると共に、使用の際にスタンド部材が邪魔に
なるようなこともない便利な一輪車を提供することを目
的とする。In view of the above problems, it is an object of the present invention to provide a convenient unicycle in which the unicycle can be easily installed in an upright state and the stand member does not get in the way during use.

ーク１と支持脚19との間に設けられている点にある。(Means for Solving the Problems of the Invention) A technical means of the present invention for solving this technical problem is that a saddle 4 is provided on an upper portion of a hawk 1 via a seat post 5, and a pair of left and right lower portions of the hawk 1 are provided. In a unicycle in which wheels 8 are rotatably supported via left and right crankshafts 9 between hawk legs 3, a stand member 17 having a base 18 and support legs 19 standing upright from the base 18 is provided. Horizontal axis 20 at the bottom of 1
And a long hole 22 is provided in the upper portion of the support leg 19, and the horizontal shaft 20 of the hawk 1 is inserted and held through the long hole 22 of the support leg 19, whereby the base 18 is positioned below the wheel 8. The support leg 19 of the stand member 17 is rotatable about the horizontal axis 20 about the horizontal axis 20 of the hawk 1 so that the stand member 17 changes its posture between the stand posture in which it is positioned and the storage posture in which the base 18 is positioned above the wheels 8. When the stand member 17 is pivoted to the retracted position, the hawk 1
An engaging member 30 that holds the stand member 17 at the storage position by engaging with each other so as to be sandwiched between the left and right sides is provided on the base 18, and the support leg 19 is provided with the elongated hole 22 with respect to the fork 1. When the stand member 17 moves upward in the range, the stand members 17 are engaged with each other so that they cannot rotate upward in the stand posture, and when the support leg 19 moves downward in the range of the slot 22 with respect to the fork 1, the stand member 17 An engaging recess 46 and an engaging projection 47, which are disengaged from each other so that they cannot be rotated upward from the stand posture, are provided between the hawk 1 and the support leg 19.
