The present invention belongs to the technical field of automobile rotating seats, and specifically relates to a turntable mechanism applied to a small-angle rotating seat for a vehicle; wherein the four corners of the turntable body are provided with turntable curved surface grooves, the T-shaped reinforcing
gasket passes through the turntable curved surface groove and is matched with the turntable body, the T-shaped reinforcing
gasket is provided with two positioning pins, the positioning pins pass through the turntable and the reinforcing
gasket buckle cover, the reinforcing gasket buckle cover is buckled on the T-shaped reinforcing gasket at the bottom of the turntable body, a self-lubricating sleeve with a sliding sleeve curved surface groove inside is placed in the matching curved surface groove, and the T-shaped reinforcing gasket, the turntable body and the reinforcing gasket buckle cover are assembled together by
welding; the present invention adopts a curved surface groove for rotation, and adopts a T-shaped gasket and a curved surface groove for matching, without the need to additionally deal with the burr problem, thereby reducing the production cost and the requirements for the
welding process accuracy, and improving the robustness and reliability of the seat.
