FIG. 9 is a perspective view showing a conventional car stopper, and FIG. 10 is a plan view showing an idling roller plate of the conventional car stopper.
As shown in FIGS. 9 and 10, the conventional vehicle stopper is a plurality of idling rollers 21 on which the driving wheels of the vehicle ride, and a stop that rotates in contact with the side of the driving wheels of the vehicle when it can be raised and lowered. And a rubber braking plate 23 attached to a lower portion of the idling roller 21 so as to be movable up and down.
The rolling bar 22 and the rubber brake plate 23 are interlocked. As the rolling bar 22 is lowered, the rubber brake plate 23 is raised and pressed against the lower part of the idle roller 21, thereby causing the idle roller 21 to move. The rotation is locked. On the other hand, as the rolling bar 22 rises, the rubber braking plate 23 descends and separates from the idling roller 21, so that the idling roller 21 rotates freely.
According to the conventional car stopping device configured as described above, the car is parked and started as follows.
First, when parking, the stopping rolling bar 22 is lowered. As a result, the rubber braking plate 23 rises and is pressed against the lower portion of the idling roller 21. As a result, since the rotation of the roller 21 is locked, the wheel rides on the idling roller 21. Thereafter, the rolling bar 22 is raised. As a result, the rubber braking plate 23 is lowered and separated from the idling roller 21, so that the idling roller 21 rotates freely. Thus, parking is completed. In this state, even if an attempt is made to depart the vehicle, the idling roller 21 and the rolling bar 22 also rotate with the rotation of the wheel, so that the wheel idles and cannot be departed.
On the other hand, when leaving the vehicle, the rolling bar for stop 22 is lowered. As a result, the rubber braking plate 23 rises and is pressed against the lower portion of the idling roller 21. As a result, the rotation of the roller 21 is locked, and the vehicle can be started.

According to the above-described conventional vehicle stopping device, the vehicle can be started and blocked by operating the stopping rolling bar 22 and the rubber braking plate 23, so that the vehicle can be stolen, parked without permission, or withdrawn without permission. Can be prevented.
However, the conventional car stopper has the following problems.
(A) Since it is necessary to interlock with the rolling bar 22 and the rubber braking plate 23, the structure becomes complicated.
(B) Since the wheel hits the rolling bar 22 during parking, its durability becomes a problem.
(C) Since the rotation of the idling roller 21 is locked by pressing the rubber brake plate 23, there is a fear that the lock is not applied due to wear of the rubber brake plate 23 or intrusion of sand or the like.
Accordingly, an object of the present invention is to provide a car stop device that can prevent theft, unauthorized parking, or withdrawal without permission with a simple structure, and that is excellent in durability.

The present invention has been made to achieve the above object, and is characterized by the following.
