きるようにして、シリンダに無理な力がかかることを避
ける機構になっている場合が多い。The ends of the hydraulic cylinder are often mounted using spherical bearings or the like to allow some rotation and rocking relative to the cylinder axis to avoid applying excessive force to the cylinder.

えられ可動部のガタを吸収できる構成が可能であるが、
水中ではシール等の問題があり複雑な構造とならざるを
得ない。When detecting the expansion/contraction stroke in a telescopic mechanism that has such play, a non-contact type (for example, a differential transformer) can be considered, and a configuration that can absorb the play of the movable part is possible.
Underwater, there are problems with seals, etc., and the structure has to be complicated.
又接触式検出方法の場合通常ラックピニオン式が考えら
れるがこの場合ガタによる歯の噛合いをうまく逃がす工
夫が必要であり、従来、確実に、かつ脚ケースの中に収
納可能なほどの大きさで伸縮ストロークを検出できる機
構は見受けられない。In addition, in the case of a contact type detection method, a rack and pinion type is usually considered, but in this case, it is necessary to devise a way to effectively release the meshing of the teeth due to play, and conventionally, the detection method is large enough to be reliably stored in the leg case. There is no mechanism that can detect expansion and contraction strokes.
