より、抜脱される。FIG. 6 shows an example of a conventional fastener composed of a combination of face-to-face engaging fastener members having the same shape. The pair of face-to-face engaging fastener members 1 include a base portion 2 and a plurality of headed protrusions 3 that are erected on the base portion 2 with a predetermined spacing. Each headed stem 3 is provided with a leg portion 5 that projects from the main surface 4 of the base portion 2 in a substantially upright state, and a head portion 6 that is connected to an end of the leg portion 5. When the two fastener members 1 are engaged with each other, the heads 6 of the headed stems 3 are opposed to each other and the base portions 2 are
Are arranged substantially in parallel (FIG. 6 (a)). In that state, when a predetermined pressure is applied to each base portion 2 in the mutually approaching direction, the head 6 of the headed stem 3 of one fastener member 1 has its top surface 7 at the headed protrusion of the other fastener member 1. Top surface 7 of head 6 of child 3
Slide along, and thus the legs 5 of both headed stems 3
While elastically bending, the other end of the fastener member 1 of the other fastener member 1 enters between the adjacent leg portions 5 (see FIG. 6).

In this state, the plurality of headed protrusions 3 of the one fastener member 1 are engaged with the bottom surface 8 of the head 6 of the fastener member 1 on the bottom surface 8 of the head 6 of each of the headed protrusions 3 of the other fastener member 1. To meet. In this way, the pair of face-to-face engaging fastener members 1
Are attached to each other. The two fastener members 1 attached to each other apply a predetermined pulling force to each base portion 2 in the separating direction to elastically bend the leg portions 5 of the headed protrusions 3 of both base portions 8 and the bottom surfaces 8 of each other. When the head 6 is disengaged against the engagement of the above, it is pulled out.

揮できなくなる課題がある。In order to obtain a strong adhesive force when an adhesive is applied to the back surface of the base portion of a surface-engaging fastener member or a pressure-sensitive double-sided adhesive tape is applied,
Generally, the back surface of the base is subjected to surface treatment such as primer treatment in advance. Surface-treating the bases of a large number of face-to-face fastener members increases the working time and increases the manufacturing cost. Further, it is difficult to repeatedly apply the primer to the bases of the many face-to-face fastener members with a uniform thickness, and as a result, there arises a problem that a uniform fixing function cannot be given to the many face-to-face fastener members. In particular,
When the base is made of a highly adhesive polymer material such as nylon or polyacetal, the adhesion may not be sufficiently improved even if a primer is applied. Thus, fixing the face-to-face engaging fastener member to the surface of the object via the adhesive while the improvement of the adhesiveness is insufficient, not only the desired initial adhesive strength of the adhesive cannot be obtained, but also the high-temperature environment, for example. When placed underneath, the adhesive strength of the adhesive significantly deteriorates over time,
There is a problem that the base part is easily peeled off from the surface of the object and the fastener function cannot be exhibited.
