When the stud tip 23 looks round, the operator can confirm that the stud fixing tool 1 has been sufficiently pushed into the panel 2. In this case, if the opening / closing piece 18 and the stud tip 23 are formed in different colors so as to provide a contrast by, for example, turning the stud tip 23 white, the confirmation can be further facilitated.

FIGS. 8A and 8B show a state in which the stud engaging portion 6 is not sufficiently pressed against the panel 2. FIG. If the pushing is insufficient, the opening / closing pieces 18, 18
Opening is small. Therefore, as shown in the bottom view of FIG. 8B, when the operator looks at the stud receiving hole 5, the tip 23 of the stud 3 does not look round. Thus, when the entire stud tip 23 is not visible, it can be confirmed that the stud engaging portion 6 is not sufficiently pushed into the stud. In this case, the worker attaches a finger or the like to the vicinity of the outlet 17 of the stud receiving hole 5 on the bottom surface of the stud engaging portion 6,
What is necessary is just to push in the stud engagement part 6. After that,
Again, it can be confirmed from the exit side of the stud receiving hole 5 that the tip 23 of the stud 3 is round. This ensures that the stud fixing tool 1 is pushed to a sufficient position.

In the above embodiment, the stud fixing tool is exemplified as a fixing tool for attaching a pipe. However, other components may be attached. By way of example, some clamps hold and attach decorative parts to the body panel of a motor vehicle, while others hold the clamps so that they hold down another panel against the panel. Further, the stud fastener need not be for mounting other mounting components. Further, in the embodiment, the stud is described as a screw stud having a thread formed on the outer peripheral surface, but may be a stud having a circumferential groove formed.

[0017]

According to the stud fixing device of the present invention, when the stud is sufficiently pushed into the stud receiving hole, the pair of opening / closing pieces of the stud engaging portion are accommodated when the stud is opened on both sides by the projecting operation of the stud. Although it hardly protrudes from the top of the stud, it is open to both sides, and when viewed from the exit direction of the stud receiving hole, the entire stud tip surface, that is, the stud tip looks round, and the worker presses the stud properly into the stud. On the other hand, if the stud tip surface is partially visible, the operator has to push it further because the pushing is insufficient, and thus the stud tip can be seen through the opening / closing piece. By visually observing, the degree of pushing into the stud can be easily known, and it can be ensured that the stud is pushed to a sufficient position. When the pair of opening / closing pieces of the stud engaging portion are opened to both sides by the stud projecting operation, the fingers hardly protrude from the top of the accommodating portion. Therefore, a finger is directly put on the outlet portion of the stud receiving hole of the stud engaging portion.
