one or more vibrators each configured to apply vibration to a portion of the vehicle seat, the portion being to be in contact with the occupant; and
a vibration application control processor configured to cause each of the one or more vibrators to vibrate with a vibration application waveform, the vibration application waveform comprising a frequency component that is higher than or equal to 100 hertz and lower than or equal to 300 hertz and comprising an amplitude that varies in accordance with acceleration acting on the vehicle,
wherein the vibration application control processor is configured to make an increase in the amplitude of the vibration application waveform in accordance with an increase in the acceleration, and to decrease a ratio of an amount of the increase in the amplitude of the vibration application waveform to an amount of the increase in the acceleration in accordance with an increase in an absolute value of the acceleration.
