To provide a structure which does not cause false operation even when touched unintentionally and is excellent in durability and smooth movement in an operation member to unlock a gas cylinder for a seat.SOLUTION: A knob 12 is a rotary type, and in its boss part 49, a ball holding groove 59 and a wire holding groove 61 are formed. When the knob 12 is rotated, a ball 43 moved upwards and the wire 42 is drawn (wound up), and the gas cylinder is unlocked. Since the knob 12 is the rotary type, false operation does not happen even when the fingertips of a person strongly touch it. An inner peripheral surface 61a of a wire holding groove 61 is formed into a non-circular shape near a shaft center O3 of the knob 12. When the knob 12 rotates, the wire 42 is deformed and presents a tendency to wind the inner peripheral surface 61a of the wire holding groove 61, but bending of the wire 61 is suppressed, so that durability can be improved and the movement can be smoothed.SELECTED DRAWING: Figure 11

    【課題】座用ガスシリンダのロックを解除する操作部材において、不用意に触れても誤操作は発生せず、かつ、耐久性と動きのスムース性とに優れた構造を提供する。【解決手段】摘み12は回転式であり、そのボス部49に、ボール保持溝59とワイヤー保持溝61とが形成されている。摘み12を回転させると、ボール43が上方に移動してワイヤー42が引かれ(巻き上げられ)、ガスシリンダのロックが解除される。摘み12は回転式であるため、人の指先が強く振れても誤操作は生じない。ワイヤー保持溝61の内周面61aを、摘み12の軸心O3に寄った非円形に形成している。摘み12が回転するとワイヤー42が変形してワイヤー保持溝61の内周面61aを巻く傾向を呈するが、ワイヤー61の曲がりが抑制されるため、耐久性を向上できると共に動きもスムース化できる。【選択図】図11
