Abstract

PURPOSE:To also lock a bicycle by working a stand of the bicycle. CONSTITUTION:A connecting means, connected to a stand for self-supporting a bicycle, is provided partly in a bar unit for a stopper by which partly a lock is formed to impede rotation of a wheel. In this connecting means, a rotary movement of the stand is transmitted to the above-mentioned bar unit to perform locking/unlocking. Accordingly, the lock is not only facilitated in its locking but also prevented from forgetting locking because an impact sound for locking is surely generated, when the stand is actuated, with the key only required to be drawn out by this sound as a sign.
