As described above, as the link unit 150 is rotated, the link unit 150 and the gate bar 20 coupled by the fixed shaft unit 21 also rotate with the reciprocating member 160 which moves slowly. As shown in FIG. 4, the control unit 40 stops the operation of the power transmission device 30 when the rotating gate bar 20 is fully raised. The operation of the gate bar 20 is stopped and the entrance of the parking lot is opened, so the vehicle passes through the vehicle breaker.

After the vehicle passes through the vehicle breaker, the gate bar 20 must be returned to its original position. That is, when the proximity sensor detects that the vehicle has passed and sends a detection signal to the controller 40, the controller 40 corresponds to the corresponding signal. The signal is sent to the power train 30 to actuate the gate bar 20.

That is, a rotational force is generated in which the shaft of the motor 110 rotates in the reverse direction according to the signal sent from the control unit 40. Accordingly, the nut shaft 140 also rotates in the reverse direction. In accordance with the rotation of the 14, the reciprocating member 160 rotates while being slowly inserted into the rotating shaft 130 while moving downward in the housing 10.

In addition, the link unit 150 is coupled to the first link 151 coupled to the downward reciprocating member 160 to move downward and at the same time the second link 152 is moved upward. Rotating around the fixed shaft portion 21, the elastic portion 171 of the balance maintaining member 170 is reduced by the elastic force to return to the original position to balance the link portion 150.

Then, as shown in FIG. 5, the gate bar 20 moves slowly until it is positioned side by side with the ground, as shown in FIG. 5, according to the rotation of the link unit 150. 40 stops the operation of the power transmission device 30, the gate bar 20 is completely stopped to block the entrance of the parking lot to limit the entry of the vehicle.

As described above, the power transmission device 30 that is provided in the housing 10 of the vehicle breaker, that is, the motor 110, the hollow rotating shaft 130, the nut portion 140, the link portion 150 and By the reciprocating member 160 and the balance maintaining member 170, the gate bar 20 is quickly moved up and down at a constant speed stably without shaking, as well as the rising and falling of the gate bar 20 precisely. Since the vehicle breaker is made smoothly because of the vehicle breaker, as well as preventing the safety accident by the gate bar 20 is very useful design.
