Abstract

PURPOSE:To reduce cost by setting the installation position of a stationary member such as a screw at an optimum position from an operating performance point of view. CONSTITUTION:An installation hole 6 is set at a position in core material 7 where a screw 25 is fastened easiest, before the core material 7 has been molded. In the periphery of the installation hole 6 of the core material 7, an area not coated with adhesives is formed. The core material 7 which has been molded through a forming process, is extruded into a synthetic resin coated layer 8 while being bonded with adhesives 9. At the time of this molding, a window panel guide section 2 of the synthetic resin coated layer 8 in the area not coated with adhesives, is formed with a partially thickened section 11 the thickness of which is higher than the height of the head section 26 of the screw 25. After the aforesaid molding has been over, a cylindrical relief hole 12 capable of housing the head section 26 of the screw 25 is formed in the partially thickened section 11 coaxially with the installation hole 6. This constitution thereby prevents a window panel 30 from interfering with the head section 26 of the screw 25.

[0005]

In the above-mentioned conventional example, the screw 117 is installed in the window panel 1 so that the end surface of the window panel 102 and the head of the screw 117 do not interfere with each other.
It is attached to the passenger compartment side more deviated than 02. For this reason, when the glass run 104 is assembled to the sash 103, the seal lip 106 on the passenger compartment side becomes an obstacle, so that the seal lip 106 is placed inside the wind panel guide portion 105 as shown by the alternate long and short dash line in FIG. The screw 117 must be tightened, either by pushing it in, or by rolling it outward, as shown in phantom in FIG. Therefore, it requires a great deal of labor and time to attach the glass run 104, specifically, the fastening operation of the screw 117, which is disadvantageous in terms of cost.

Therefore, in the present invention, the mounting position of the fixing member such as a screw is set to a position having the best workability without considering the interference with another member such as a wind panel to reduce the cost. The challenge is to achieve.

[0007]

DISCLOSURE OF THE INVENTION The present invention provides an extruded product containing a core material, wherein a synthetic resin coating layer is extruded while being bonded with an adhesive to a preformed core material having attachment holes, While the adhesive uncoated area is formed around the core material mounting hole, the synthetic resin coating layer in the adhesive uncoated area has a thickness greater than the height of the head of the fixing member to be inserted into the mounting hole. A thick uneven thickness portion is formed, and an escape hole communicating with the attachment hole is formed in this uneven thickness portion.

[0008]

[Function] A fixing member such as a screw for mounting the extrusion molded product is inserted from the escape hole into the attachment hole of the core material, and the head of the fixing member is housed and arranged in the escape hole, and inside the welt portion rather than the uneven thickness portion. Does not stick out. Therefore, another member such as a wind panel close to the extruded product is blocked by the synthetic resin coating layer and does not interfere with the head of the fixing member.
