その軟質母材を摩耗させ、タツプ欠を正規の位置
に確保できなかつた。特に、力が加わるところで
はその摩耗が早くタツプ穴の寿命が著しく短いな
どの欠点があつた。 Conventionally, in this type of tap erecting, weak points in the soft base material have been reinforced using heliserts and the like. Therefore, a special tool is required to insert the helisert, and when the bolt is repeatedly attached and removed, the helisert wears its soft base material, making it impossible to secure the missing tap in the correct position. In particular, there were drawbacks such as rapid wear in areas where force is applied, and the life of the tap hole was extremely short.

Figures 1a and c are front views of members 1 and 2 used in the first embodiment of the present invention, Figures b and d are side views thereof, and Figure 2a is the first embodiment. (The surface of the soft base material 3 is shown with diagonal lines because it is too large to show its outline), and Figure b is a sectional view taken along the line A-A.
The member 1 has a male thread 11 formed on its outer periphery and a female thread 12 formed on its inner periphery, and is provided with a stepped head 13 on which a flat surface 14 is provided. The inner periphery 21 of the member 2 has a shape that fits into the head 13, and its flat portion 22 has the same size as the flat surface 14. On the outer periphery of the member 2, a shallow axial groove 23 with a narrow pitch is formed over the entire circumference (as it is a shallow groove, it is not shown in Figure 1c, and only a portion is depicted in Figure 1d). . A stepped cylindrical recess is provided in the soft base material 3 from its surface toward the inside, and a female thread 31 that fits the male thread 11 is formed on the inner wall of this recess. The diameter of the opening 32 of the recess is very slightly smaller than the outer diameter of the member 2. A member 1 is fixed to a soft base material 3 using its male screw 11. Next, to prevent member 1 from rotating away, member 2
By aligning the inner periphery 21 of the member 1 with the head 13 of the member 1 and driving it into the opening 32 of the soft base material 3, the reinforced tapped hole structure is completed.

FIG. 4a is a front view of the second embodiment of the present invention constructed using these members 4 and 5 (however, since the soft base material 3 is too large in shape and its outline cannot be illustrated, diagonal lines are drawn on the surface. ), and FIG. b is a sectional view taken along the line B-B. In this embodiment, a flat surface 14 for detent
is formed by partially cutting out the male screw 11 of the member 4. The member 5 having a flat portion 22 to be in contact with the flat surface 14 is driven between the wall surface 35 of the recess of the soft base material 3 and the member 4. Like member 2, member 5 has a shallow groove 23 in the axial direction, so that member 4 is tightened to the soft base material.
