脚台形状断面の環状ゴムパツキン片５ｂをはめる。The outer periphery of the case 9b is provided with an inner periphery that engages with the case, and an annular rubber packing piece 5b having an isosceles trapezoidal cross section and a height commensurate with the radial dimension of the packing chamber 2b is fitted.
該パツキン片５ｂの左側に断面台形状のパツキン締付金
具７を介して２つのスプリング締付金具１を配設し、前
記パツキン片５ｂの右側および頂部に、ケーブル接続部
をおおう円筒状の接続箱２の肉厚端部近傍に同心円筒状
にえぐられ形成されたパツキン室２ｂを当接する。Two spring fastening fittings 1 are disposed on the left side of the packing piece 5b via a packing fitting 7 having a trapezoidal cross section, and a cylindrical connection that covers the cable connection part is provided on the right side and top of the packing piece 5b. A packing chamber 2b formed by hollowing out a concentric cylinder is brought into contact with the vicinity of the thick end of the box 2.
前記パツキン室５ｂの上部に形成された縦フランジ２ａ
と前記スプリング締付金具１との間に、前記パツキン片
５ｂを軸方向にしめつける押圧力を作用させている。A vertical flange 2a formed on the upper part of the packing chamber 5b.
A pressing force is applied between the spring clamping member 1 and the spring clamping member 1 to tighten the packing piece 5b in the axial direction.
なお、１３はケース９ｂが接続箱２に対して、第２図に
おいて左にうごかないようにするため、ケース９ｂ外周
に螺合する内周をそなえた画形のストッパ、１５はナツ
トである。In addition, 13 is a stopper in the shape of a picture having an inner periphery that is screwed onto the outer periphery of the case 9b in order to prevent the case 9b from moving to the left in FIG. 2 with respect to the connection box 2, and 15 is a nut.
