<P>PROBLEM TO BE SOLVED: To provide a bicycle unlocked-state alarm device that makes a user not forget the locking of a bicycle when parking it. <P>SOLUTION: The bicycle unlocked-state alarm device includes: a stand for making the bicycle autonomously erect; a stand switch 4 which changes opening/closing states depending on the case that the stand makes the bicycle autonomously erect and the case that the stand does not make the bicycle autonomously erect; a lock for wheel locking; a lock switch 25 which changes the opening/closing states depending on the case that the lock locks the wheel and the case that the lock does not lock the wheel; and the alarm device 31. The alarm device 31 issues an alarm when the lock switch 25 is in the opening/closing state at the wheel locking though the stand switch 4 is in the opening/closing state at the autonomous erection. A timer switch 34 which is brought into the closed state after the lapse of a prescribed time after the stand makes the bicycle autonomously erect is inserted into a drive circuit 33 of the alarm device 31. <P>COPYRIGHT: (C)2013,JPO&INPIT |
