FIXING DEVICE FOR HOLDING SENSOR AND METHOD FOR FIXING AND ADJUSTING SENSOR

To provide a fixing device capable of holding a sensor at a working position inside the fixing device and finely adjusting the working position.SOLUTION: The fixing device comprises: a main body 2 having a first through hole 2a and fixable to a holder; and a holding element 3 having a second through hole 3a and movably provided in the main body 2 so as to slide between first and second positions and a holding position. The fixing device is positioned so as not to arrange the first and second through holes 2a and 3a in a straight line at the first position while it is positioned so as to arrange the first and second through holes in a straight line at the second position, and the holding element 3 presses a sensor, which can be placed inside the first and second through holes, against the main body 2 at the holding position. An adjustment element 4 placed radially inward so as to be tilted to a central axis of the second through hole is provided in the second through hole and engages with the outside surface of the sensor. The sensor can rotate when the holding element is located at an adjustment position between the second position and the holding position, and when rotating, the adjustment element 4 moves the sensor along a central axis MA.SELECTED DRAWING: Figure 2 【課題】固定装置内で作動位置にセンサを保持して、作動位置を微調整できる固定装置を提供する。【解決手段】第１の貫通孔２ａを備え且つホルダに固定可能な本体２と、第２の貫通孔３ａを備え且つ第１及び第２の位置と保持位置との間でスライド可能に本体２内に可動に配置される保持要素３とを含み、第１の位置では第１及び第２の貫通孔２ａ、３ａが互いに一直線にならずに位置合わせされ、第２の位置では第１及び第２の貫通孔が互いに一直線となり位置合わせされ、保持位置では保持要素３が第１及び第２の貫通孔の内部に配置可能なセンサを本体２に押し付ける。第２の貫通孔には半径方向に内側へ向き且つ第２の貫通孔の中心軸に対して傾いた調整要素４が設けられ、調整要素がセンサの外側面と噛み合い、保持要素が第２の位置と保持位置との間で調整位置にあるときにセンサが回転でき且つ回転すると調整要素４が中心軸ＭＡに沿ってセンサを移動させる。【選択図】図２
