Seat device

Abstract

A seat device that can easily and reliably achieve the conversion of the state of a seat. A rotation mechanism (40) that rotates the seat about a rotation axis, a sliding mechanism (14) that advances and retracts the seat together with the rotation mechanism (40) from a fixed side, and a drive mechanism (50) that sequentially and directly drives each of the sliding mechanism (14) and the rotation mechanism (40) are included. The drive mechanism (50) includes a power source (51) provided in the fixed side of the seat, and transmission means for directly driving the sliding mechanism (14) first, and then directly driving the rotation mechanism (40), in a process of converting the state of the seat with power of the power source (51). Here, the transmission means is formed by a sprocket (58) rotated by torque of a motor (51), and many holes (59) with which the sprocket (58) is rotatably engaged to transmit the power.
