ロツキング装置。 The seat body is attached to a support mechanism attached to the upper part of the leg body of the chair via a weight sensitive mechanism so as to tilt backward or downward according to the load on the seat body, and a backrest support body to which a backrest is attached is attached. A spring body is pivotably mounted to allow rearward tilting movement and is located between the support mechanism and the backrest supporter and elastically supports the rearward tilting movement of the backrest supporter, and is movable far and near with respect to the pivoting portion of the backrest supporter. Meanwhile, a moving means such as a link mechanism is provided between the support mechanism and the seat body to move the spring body in a direction away from the pivot portion of the backrest support body when the seat body tilts backward or moves downward.
