To provide a lifter device for maintaining a seat height after adjustment by engaging a lock pole (called a main pole) to a gear which is rotated in linkage with a height adjustment of a seat, in which, in release time of engagement of the gear and the main pole for height adjustment, sudden reduction of a load applied to the main pole is relaxed by a sub pole for sharing a load which is in parallel relationship with the main pole, for suppressing occurrence of allophone in release of engagement of the gear and main pole, without size increase of a rotary controller of the gear of the lifter device.SOLUTION: The lifter device is configured so that, according to a rotation in a direction for lifting or lowering a seat (1) of an input member (41), engagement between a main pole (32), 33 and an inner tooth 34 is released, then, after engagement between the main pole 33 and the inner tooth is released, engagement of sub poles 38 and the inner tooth 34 is released, at the time, engagement release of sub poles 38 is performed.SELECTED DRAWING: Figure 20

    【課題】シートの高さ調整に連動して回転するギヤにロック用ポール(メインポールという)を噛み合わせて調整後のシート高さを維持するリフタ装置において、高さ調整のために行うギヤとメインポールとの噛み合い解除時に、メインポールが受ける荷重の急減を、メインポールと並列関係の荷重分担用のサブポールにより緩和する。それによりリフタ装置のギヤの回転制御装置を大型化することなく、ギヤとメインポールとの噛み合い解除時の異音の発生を抑制する。【解決手段】入力部材(41)のシート(1)を上昇又は下降させる方向への回転に応じて、メインポール(32)、33は内歯34との噛合を解除され、サブポール38は、メインポール33より遅れて内歯34との噛合が解除され、しかも、サブポール38の噛合解除が漸次行われるように構成されている。【選択図】図20
