In this paper, author evaluated the influence on the human body from the physical quantity of vibration received from rides and the response (psychological/physiological response) of the human body, from the ergonomics point of view. Rides are roughly classified into two types. One performs mainly a linear running motion which includes elevated facilities such as roller coasters. The other performs a rotary motion by power about the plumb or variable axis which includes merry-go-rounds, Ferris wheels and the like. As the index for studying the influence on the human body, author adopted the SD method (Semantic Differential method) for analyzing feeling, impression, etc, due to motion of the ride in respect or psychological response, and the electrocardiogram and the respiration exercise in respect of physiological response.
