However, the chair having a conventional tilting means has a structure in which a spring or the like, which is an elastic means for providing tilting, is placed in a vertical direction, so that a person who directly rotates the rotating body located below the bottom surface is required to adjust the strength of the spring.

Therefore, in order to rotate the rotating body, the seated person must come down to the chair or artificially bow his / her head and waist deeply so that the hand touches the rotating body, and also rotate the rotating body with the force corresponding to the spring strength to adjust the tilting strength. Therefore, considerable physical force must be applied.

In the structure of the conventional chair, the seated person has to be constantly providing a large force in a very uncomfortable posture, which causes a significant inconvenience. In addition, the tilting intensity should be naturally adjusted according to the seating state of a person sitting on a chair. If a person needs to adjust the tilting strength to come down to a chair or lean his back deeply as in a conventional chair, the seating state of the current seated person is reflected as it is. There is a problem in that it is necessary to repeat the useless control action.

Due to these problems, the tilting strength adjustment function added to the conventional chair is becoming a useless function that is rarely used.
