PROBLEM TO BE SOLVED: To securely operate a collision rock mechanism by reducing a displacement amount between a rotator and a non-rotator of a rotating mechanism in a rotating direction at a collision of a vehicle. SOLUTION: In a seat rotation slide device, a rotation regulating mechanism 40 comprises: a hook-like mechanism 43; and a hook receiving member 45. The hook-like mechanism 43 comprises: a fixed bracket 41 mounted on a rotator 25 of the rotating mechanism 20 so as to regulate positions by a plurality of connecting means; and a hook 42 rotatably connected with the fixed bracket 41 to engage with the hook receiving member 45 by an elastic force. The fixed bracket 41 is mounted on the rotator 25 of the rotating mechanism 20 by the connection means at a position equivalent to a top of a virtual polygon formed in a rotation center C of the hook 42 over an inner side and an outer side in a rotation radius direction of the seat body 10.
