To improve the attaching/detaching property of a sensor holder while maintaining the closability of a fluid chamber in an assistor.SOLUTION: An assistor 10 comprises: a cylinder shell 1; a stopper 3 disposed in a fluid chamber 2; an adapter 4 placed opposite the stopper 3 across a bottom 1a of the cylinder shell 1; and a bolt 5 for fixing the stopper 3 and the adapter 4 to the cylinder shell 1. The stopper 3 includes: a restriction part 3a into which a detection rod 6B of a sensor 6 is inserted; and a first flange part 3b that comes into contact with the bottom 1a. The adapter 4 includes: a support part 4a into which the detection rod 6B is inserted; a second flange part 4b that comes into contact with the bottom 1a; and a fastening part 4c bulged from the second flange part 4b in a direction away from the bottom 1a. The bolt 5 is inserted into bolt holes 3h and 1h which penetrate the first flange part 3b and the bottom 1a from the first flange part 3b side so as to be coupled with a female screw part 4g which is recessed from the second flange part 4b to the fastening part 4c.SELECTED DRAWING: Figure 4

    【課題】倍力装置において、流体室の密閉性を維持しつつセンサホルダの着脱性を向上させる。【解決手段】倍力装置10は、シリンダシェル1と、流体室2内に配置されたストッパ3と、シリンダシェル1の底部1aを挟んでストッパ3と対向配置されたアダプタ4と、ストッパ3及びアダプタ4をシリンダシェル1に固定するボルト5とを備えている。ストッパ3は、センサ6の検出ロッド6Bが挿通される規制部3aと、底部1aに当接する第一フランジ部3bとを有する。アダプタ4は、検出ロッド6Bが挿通される支持部4aと、底部1aに当接する第二フランジ部4bと、第二フランジ部4bから底部1aと離隔する方向に膨出形成された締結部4cとを有する。ボルト5は、第一フランジ部3bと底部1aとを貫通するボルト孔3h,1hに第一フランジ部3b側から挿通され、第二フランジ部4bから締結部4cへ凹設された雌ねじ部4gに締結される。【選択図】図4
