PROBLEM TO BE SOLVED: To provide a seating device in which the number of use of an elastic member can be suppressed in a mechanism part for turning an armrest.SOLUTION: A seating device includes: a fixed gear 13 fixed in a seat back, and has fixed gear teeth 13d; a lock gear 14 with a first arm 14b and a second arm 14c rotatable around a lock gear rotating shaft 14a, and having lock gear teeth 14d engaging with the fixed gear teeth in the first arm; a lever plate 15 with a third arm 15b and a fourth arm 15c rotatable around a lever plate rotating shaft 15a, and having the third arm engaging the first arm; and an elastic member 16 mounted to the second arm and the fourth arm, and biasing the second arm and fourth arm so as to approach to each other. When the fourth arm is rotationally operated to be separated from the second arm, the third arm makes the first arm be rotationally operated in the direction becoming the unlocking state. When the fourth arm is rotationally operated to approach the second arm, the third arm makes the first arm be rotationally operated in the direction becoming a locked state.SELECTED DRAWING: Figure 3

    【課題】アームレストを回動する機構部において弾性部材の使用数を抑えることのできる座席装置を提供する。【解決手段】シートバックに固定され固定ギア歯13dを有する固定ギア13と、第1の腕14bと第2の腕14cがロックギア回転軸14aを中心に回転可能であって、固定ギア歯と噛み合うロックギア歯14dを第1の腕に有するロックギア14と、第3の腕15bと第4の腕15cがレバープレート回転軸15aを中心に回転可能であって、第3の腕が第1の腕に係合するレバープレート15と、第2の腕と第4の腕に取り付けられ、第2の腕と第4の腕を互いに近づくよう付勢する弾性部材16とを備え、第4の腕が第2の腕から離れるように回転動作すると、第3の腕が第1の腕をロック解除状態となる方向に回転動作させ、第4の腕が第2の腕に近づくように回転動作すると、第3の腕が第1の腕をロック状態となる方向に回転動作させる。【選択図】図3
