PROBLEM TO BE SOLVED: To provide a spring damper which prevents the generation of noise caused by a collision of a spring wire.SOLUTION: A spring damper 35 possessed by an accelerator device is arranged inside a hysteresis spring 49 possessed by a hysteresis mechanism part. The spring damper 35b is formed of a main body part 36 having an outside diameter D36 which is smaller than inside diameter Di49 of spring wires 493 of the hysteresis spring 49 which is arranged at an inner wall 102 of a housing 10 and at a lock part 431 so as to be capable of abutting thereon, and an outside protrusion 37 which is formed outside the main body part 36 in a radial direction, and has a tip 371 which is located outside the radial direction rather than a cylindrical virtual face VP49 which passes centers of the spring wires 493. When the hysteresis spring 49 is compressed by the pedal-in of an accelerator pedal by a driver, the outside protrusion 37 which is located between the adjacent spring wires 493 prevents that the spring wires 493 collide with each other.SELECTED DRAWING: Figure 4

    【課題】 ばね線の衝突による異音の発生を防止するスプリングダンパを提供する。【解決手段】 アクセル装置が備えるスプリングダンパ35は、ヒステリシス機構部が有するヒステリシスばね49の内側に設けられている。スプリングダンパ35は、ハウジング10の内壁102及び係止部431に当接可能に設けられヒステリシスばね49のばね線493の内径Di49より小さい外径D36を有する本体部36、並びに、本体部36の径方向外側に設けらればね線493の中心を通る筒状仮想面VP49より径方向外側に位置する先端371を有する外側凸状部37から形成されている。運転者のアクセルペダルの踏み込みによってヒステリシスばね49が圧縮されるとき、隣り合うばね線493の間に位置する外側凸状部37は、ばね線493同士が衝突することを防止する。【選択図】 図4
