A pin secured at one end of a link is inserted into an L-shaped groove of a ock lever pivoted to the upper surface of an upper guide rail and the other end of the link is connected to an actuator by way of a wire. The hook of the lock lever can be inserted into the hook hole of the flange of the lower guide rail. Rotating of the lock lever and thus rotation of the upper guide rail relative to the lower guide rail by an accidental external force to the lock lever can be prevented in the rotatable seat.

[ What is claimed is:] [1.] A rotation mechanism for a rotatable seat comprising a lower guide rail adapted to be supported on rail means mounted to a vehicle floor, an upper guide rail rotatable relative to the lower guide rail and adapted to secure a seat cushion thereon, a lock lever equipped with a handle and pivoted on the upper guide rail, an actuator supported on the upper guide rail, and a link engagably connected at one end to the lock lever and connected at another end with the actuator so as to restrict the rotation of the lock lever by engagement thereof when a hook at one end of the lock lever engages a hook hole of the lower guide rail, manual rotation of the lock lever being enabled when the actuator rotates the link by an electric current supplied to the actuator, thereby releasing engagement between the hook of the lock lever and the hook hole of the lower guide rail to allow the rotation of the seat.
