性を向上できるようにしてある。As shown in FIGS. 5 to 8, the end face plate 3 is provided with a rubber spacer having four cable insertion holes 20 of equal diameter or different diameter, and a slit 22 for each hole.
A cable can be inserted and fitted by opening the end, and the change of the hole diameter of the cable insertion hole 20 and the cable diameter is performed through the end face plate 3. A seam spacer having a mountain groove on both sides made of plastic is inserted in the middle portion of the slit 22, and the diagonal slit 22 has a thin wall on one side and the outer peripheral surface of the end face plate 3 when the cable is not inserted. The cap portion 21 of the insertion hole can be cut and opened when the cable is inserted, which improves workability and airtight reliability. When the slit 22 is cut and used, a connecting piece 24 as an opening stopper is attached to the concave surface portion 23 in order to prevent the opening action and the deviation of the cut outer peripheral portion at the step of reclosing after inserting the cable. To be done. Further, the outermost peripheral surface of the end face plate 3 has a plurality of mountain grooves 2 over the entire circumference.
6 is provided so that a compression force with the inner surface of the sleeve is obtained to maintain airtightness, and an airtightness with the cable is obtained by the compression force transmitted to the inside. That is, in the airtightness maintaining mechanism for the fitting portion 2 of the sleeve 1 and the end face plate 3, the mountain groove 26 is provided on the outer circumference of the end face plate 3, and the sleeve 1 receives the tightening force of the band to the mountain groove 26 to maintain the airtightness. As a result, the end face plate gasket is unnecessary and the workability of assembling and disassembling can be improved.

By connecting the parts, the required tray position can be opened and the workability can be improved. In addition,
The sleeve 1 is composed of a pair of semi-cylindrical bodies that are vertically divided into two parts along the longitudinal direction, and are formed in a thicker portion toward the divided joint surface of the sleeve and are concave on the outer joint surface. Although the groove 6 is provided to ensure the maintenance of airtightness, it is also possible to select a cable direct insertion shape in which the end plate 3 is omitted.
