PROBLEM TO BE SOLVED: To provide a vibration stimulator with an increased massage effect due to favorable stimulus by allowing a vibrator to generate wavy vibration. SOLUTION: A plurality of vibrators (a vibrator 21 for a bottom part through a vibrator 24 for leg parts) driven by drive means (drive circuits 41-44) corresponding to parts of a human body are disposed in a support section of a device body (chair body) having this support section (a seat section 12 and a back rest section 13) for supporting the body. The vibrators adjacent to each other out of these vibrators are driven in two different frequencies, a first frequency and a second frequency. Also, the positional relationship between the adjacent vibrators driven in the different frequencies is changed sequentially with time by control means 45.
