Claims

[Scope of Claim for Utility Model Registration] (1) A pair of left and right seat tracks having a lower rail fixed to the vehicle floor and an upper rail fitted to the lower rail so as to be relatively slidable; a lower bracket; a rotation center protrusion formed upwardly on this lower bracket; a turn bracket fixed to the seat and having a hole that rotatably fits into this rotation center protrusion; A support lock bracket which is fixed and rotatably supports the periphery of the hole of the turn bracket between the support lock bracket and the lower bracket; A locking tooth portion provided on the periphery of the support lock bracket; a removable locking member supported on the turn bracket; and an operating member for engaging and disengaging the locking member from the locking teeth, the locking teeth and the locking member fixing at least the seat in its normal position. A seat rotation device characterized in that it is provided at a position. (2) The seat rotation device according to claim 1, wherein the locking teeth on the peripheral portion of the support lock bracket are further provided to fix the seat at other positions within the rotatable range. (3) A utility model registration claim in which a locking member and a locking tooth are provided in pairs symmetrically with respect to the center of the support lock bracket, and the pair of locking members are operated simultaneously by a single operating member through an interlocking mechanism. The sheet rotating device according to item 1.
