PROBLEM TO BE SOLVED: To provide a penetration part closing tool capable of reducing a gap between tongue pieces closing the periphery of a wiring/piping material, and an insertion part forming body for the wiring/piping material.;SOLUTION: A plurality of receiving parts 12a surrounding a conduit pipe inserted in a filler receiver 10 are formed in a thin plate shape and disposed in such a manner that sides 14 of neighboring parts 12a overlap each other. Even when an interval between the receiving parts 12a is widened toward the conduit pipe around proximal ends of the receiving parts 12a, in the state where the conduit pipe is supported, the sides 14 of the neighboring receiving parts 12a overlap each other, such that a gap is unlikely to be formed between the receiving parts 12a. Thus, even in the state where the conduit pipe is supported, a thermally expansible fireproof filler can be prevented from being dripped from a gap between neighboring receiving parts 12a.;COPYRIGHT: (C)2014,JPO&INPIT
