パツキン材が適宜用いられている。(Prior art) In this type of conventional technology, a cylindrical closure that is divided into upper and lower parts is generally used, and the cable is installed in advance on the wall of an underground tunnel that accommodates tunnel-type underground cables. The closure is manually attached to the cable receiver, and for example, when the underground cable connected near the cable receiver is housed in the closure, one worker must first attach the closure to the cable receiver. The divided lower cylindrical part is supported by hand, the cable connection part is accommodated in the lower cylindrical part, and another worker covers the upper cylindrical part from above and fixes it by screwing or other means, and then attaches the cable receiver. It is attached to hardware. Note that the terminal plates on both sides of the closure have holes through which cables can be drawn. Also, since dry gas is sealed within the cable, the closure at the closure is hermetically sealed. Therefore, a sealing material or a gas packing material is appropriately used for the terminal plate and the abutting portions of the upper and lower cylindrical portions.
