A motor vehicle seat rotation mechanism disclosed in the present invention comprises: a connecting plate (100) connected to a seat; a moving plate (200), located below the connecting plate (100) and connected in a fixed manner to the connecting plate (100); a fixed plate (300) located below the moving plate (200), the fixed plate (300) being connected to an upper slide rail in a slide rail assembly of the seat; a press plate (400), located above the moving plate (200) and connected in a fixed manner to the fixed plate (300); an upper ball assembly (500) located between the press plate (400) and the moving plate (200); a lower ball assembly (600) located between the moving plate (200) and the fixed plate (300); and further comprises: a lower anti-detachment hook ring (800), located between the connecting plate (100) and the fixed plate (300), and fixed to the fixed plate (300), with an annular lower anti-detachment hook (810) being provided at an inner edge of the lower anti-detachment hook ring (800), and an annular upper anti-detachment hook (810) being provided at an outer edge of the moving plate (200), the lower anti-detachment hook (810) and the upper anti-detachment hook (230) being engaged with 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 the 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.
