To provide a motor vehicle seat rotation mechanism having an improved locking mechanism and an improved ball assembly to solve problems affecting upper and lower steel balls in a force-bearing state in rolling rotation mechanisms.SOLUTION: The motor vehicle seat rotation mechanism comprises: a connecting plate; a moving plate 200; a fixed plate 300; a press plate 400; an upper ball assembly 500; a lower ball assembly 600; a lower anti-detachment hook ring 800; an annular lower anti-detachment hook 810; and an annular lower anti-detachment hook 230. The lower anti-detachment hook 810 and the upper anti-detachment hook 230 engage each other. The motor vehicle seat rotation mechanism of the present invention solves various problems affecting upper and lower steel balls in a force-bearing state in conventional rolling rotation mechanisms, and realizes an arrangement of a novel anti-detachment structure within a design height of the rolling rotation mechanism in the perpendicular direction of H=32 mm, such that the anti-separation strength is greater than 2000 Nm.SELECTED DRAWING: Figure 8

    【課題】本発明は、転がり回転機構において力を受けている状態の上下の剛球に及ぼす問題を解決し、改良されたロック機構、改良されたボール組立体を有する自動車シート回転機構を提供する。【解決手段】接続板、移動板200、固定板300、押圧板400、上側ボール組立体500、下側ボール組立体600、及び下側分離防止フックリング800を含み、環状下側分離防止フック810を設け、環状上側分離防止フック230を設け、下側分離防止フック810と上側分離防止フック230は相互に係合するので、従来の転がり回転機構で力を受けている状態の上下鋼球に影響を及ぼす様々な問題を解決し、分離防止強度が2000Nmより大きいように転がり回転機構の垂直方向設計高さH=32mm以内で新規な分離防止構造の装置を実現する。【選択図】図8
