Reclining device and vehicle seat

Abstract

In a reclining device, a lock mechanism locks tilting of a seat back. A knob is connected to a shaft and a connecting bracket, and in a case in which the knob is operated, the shaft and the connecting bracket are rotated, and a lock mechanism unlocks tilting of the seat back. At a time of a side collision of a vehicle, the knob is disconnected from the shaft and the connecting bracket. Therefore, even in a case in which the knob is operated by an impact load, the rotation of the shaft and the connecting bracket can be suppressed, and the unlocking of the tilting of the seat back can be suppressed.
