Abstract

The invention relates to a base structure for a chair. Primarily, a chassis comprises a circular arc protrusion formed at a center of a bottom surface thereof, and a limiting portion gradually flatted from the circular arc protrusion to a circumference of the chassis. Furthermore, a base body is provided on an upper surface of the chassis and covered by a casing cover, and the casing cover covers around the circumference of the chassis so that the chassis, the base body and the casing cover are combined and fixed with each other. In this way, the circular arc protrusion of the chassis can be used to generate relative swaying in response to changes of a user’s center of gravity when he/her sits on the chair. In addition, the flat limiting portion provided on a circumference of the circular arc protrusion of the chassis can limit the swinging angle of the chair to prevent the chair from overturning due to the excessive swinging amplitude, which may cause the user to fall from the chair unexpectedly, so as to ensure the safety of the chair.
