Since the seat is vibrated vertically and horizontally to prevent drowsiness, the seat vibrates due to the vibration generated by the vibration means, and the driver sitting on this seat does not sneak, Accidents can be completely eliminated. Further, in the first vibrating device for preventing toying driving, the vibration means is a vibration motor, and when the vibration means is fixed to a lower portion of the seat, the vibration generated by the vibration motor is transmitted to the seat, and the seat is moved. It starts to vibrate. In addition, since the vibration is generated by using the vibration motor as described above, the vibration direction of the seat can be selected by selecting the direction of the rotation axis of the vibration motor. That is, when the rotation axis of the vibration motor (or the rotation axis of the vibration motor and the rotation axis of the rotating body) is directed in a direction perpendicular to the traveling direction of the automobile, the vertical vibration is applied while the seat is vibrated up and down. In addition, a vibration that swings along the traveling direction of the vehicle can be applied. When the rotation axis of the vibration motor (or the rotation axis of the vibration motor and the rotation axis of the rotating body) is directed in the direction along the traveling direction of the automobile, the seat is vertically vibrated. Vibration that swings in a direction perpendicular to the traveling direction of the vehicle can be applied. Therefore, the driver can select the vibration direction according to his or her preference (such as shaking that makes the user sleepy). On the other hand, the second sleep driving preventing seat vibration device of the present invention is configured such that a seat is fixed to a seat support portion provided on a floor surface via a vibration isolator, and a rotating body support portion is fixed to a lower portion of the seat. And
A rotator is rotatably mounted on the rotator support, and a vibration motor is fixed to the rotator support via an anti-vibration material, and the rotator and the rotation shaft of the vibration motor are connected via a belt. Therefore, the same operation and effect as above can be obtained. Further, in the third vibration-absorbing seat vibration device of the present invention, the seat is fixed to a seat support portion provided on the floor via a vibration isolator, and the rotating body support portion is fixed to a lower portion of the seat. Then, the rotating shaft of the rotating body is rotatably mounted on the rotating body supporting portion, an unbalanced weight is provided on the rotating shaft, and a motor is fixed to the rotating body supporting portion via a vibration isolating material. Since the body and the rotating shaft of the motor are connected via the belt, the vibration generated by the rotation of the rotating shaft of the rotating body is transmitted to the seat, and the seat vibrates. Therefore, the driver sitting in this seat does not sneak, and the accident due to sneaking can be completely eliminated. In addition, as described above, there is an effect that the driver can select the vibration direction according to his / her preference. Further, in the present invention, since the seat itself vibrates, no matter what the posture of the driver is, even if the driver is drowsy and shakes his head, he / she sits on the seat. As far as possible, vibrations are always transmitted to the driver. For this reason, there is also an effect that sleepless driving can be effectively prevented.
