Conventionally, as illustrated in FIG. 4, a guide cap a consisting of a conical body with an open proximal end, a wire c,
Fixing tool b such as a crimp terminal that connects the two by caulking
A tip guide device d consisting of the following was used. This tip guide tool d connects the lead wire k to the base end j of the wire c, inserts it into the pipe e from the left opening, and blows air from the opening to connect the guide cap a to the blowgun. By running the lead wire k through the pipe e, the lead wire k is inserted into the pipe e.
このような従来の先端誘導具ｄでは、その製作
が面倒でコスト高となり、使い捨ても行ないにく
いという欠点があつた。 Such a conventional tip guiding tool d has disadvantages in that it is troublesome and expensive to manufacture, and is difficult to dispose of.
また、第４図に示すように、内周面に凹凸部を

As shown by the arrow, the air passes through the outer surface of the cap a through the concave part h of the concavo-convex part g, so that so-called air escape occurs, and the pressing force of the cap a becomes weak, or the proximal edge f becomes uneven. This cap a is attracted to part g.
There was a risk that it would not be able to pass through the pipe e properly.

る。 It can run smoothly inside the pipe 7, such as a CD pipe, which has uneven parts 24 without getting caught. Furthermore, even if the piping 7 is made of steel pipes, plastic pipes, etc., the ready-mixed concrete poured into the building adheres to a part of the inner circumferential surface and solidifies, and a protruding mass is present in a part of the piping 7. In many cases, foreign objects such as screws may be present, but in such cases, the conventional tip guide shown in Fig. 4 tends to get caught, making it difficult to insert. The invented method allows for smooth passage while greatly reducing the diameter.
