BACKGROUND OF THE INVENTION Vehicle seats, office or home chairs,
In an article such as a mattress having a cushioning core material formed of a molded article of a foamable resin material and a flexible coating material such as a cloth or leather covering the surface of the core material, the coating material is coated with a core material. In order to firmly and firmly adhere to the material,
It is known to use a face-to-face engagement type fastener member (so-called hook-and-loop fastener) in which a plurality of engagement elements are arranged on one surface (main surface) of a base (for example, Japanese Patent Laid-Open No. 9-2247).
No. 20).

[0003] In particular, for articles such as seats and chairs, it is desired to provide the user with a high level of comfort. Therefore, as a fixing means for attaching the covering material to the core material, the seam of the covering material is used. There is a tendency to use a fastener member having an elongated band shape that can be arranged in a groove provided on the surface of a core material along the same. And in order to equip such a belt-shaped fastener member in a desired position on the surface of the core material in a state where the engagement element group is exposed,
An insert molding method in which a fastener member is disposed as an insert in a mold of a core material, which is a molding main body, and the fastener member is fixed to the core material simultaneously with the molding of the core material has been advantageously implemented.

In this insert molding method, a rail-shaped holding portion for holding a fastener member in a predetermined posture in advance is laid in a mold mainly formed. The holding portion is usually configured as a rail-shaped block having a receiving groove capable of accommodating the base of the fastener member and the group of engaging elements. The fastener member is installed on the holding part with the engagement element group and the base inserted into the receiving groove of the holding part and the back surface of the base (the surface opposite to the main surface) exposed. In addition, the holding | maintenance part of the number corresponding to the number of the fastener members which should be equipped with a shaping | molding main body is laid in the shaping | molding main body. Further, when the fastener member is provided on various three-dimensional surface portions of the main body of the molding, the receiving member has variously three-dimensionally bent receiving grooves extending in order to make the fastener member follow such a three-dimensional surface. A holding unit is provided.

Conventionally, when a fastener member is mounted on a holding portion of this type, one end of the base portion of the fastener member in the longitudinal direction is substantially aligned with one end of the holding portion in the longitudinal direction.
