Abstract
The utility model provides an improvement for office chair base structure. A fixing device can selectively fix the inclining angle of a swinging piece (chair back). When a tommy bar of the fixing device is positioned at the first location, the swinging piece (chair back) ca not generate the opposite pivoting and swinging with the body, so the efficiency of fixing the inclining angle of the swinging piece (chair back) is achieved. When the tommy bar of the fixing device is positioned at the second location, the swinging piece (chair back) can incline freely. An inching device can adjust the inclining elasticity of the chair back. When a draw rod of the inching device is positioned at the somewhat rear area, an elastic body is not drawn by the draw rod. At the same time, the inclining elasticity of the swinging piece (chair back) is softer. When the draw rod of the inching device is positioned at somewhat front area, the elastic body is stretched. At the same time, the inclining elasticity of the swinging piece (chair back) is harder. The utility model is the improvement design with the use and the progress of the industry.
