Further, an assist grip 70 is provided in front of the armrest 60 so as to extend obliquely upward from the front end of the armrest 60 to the front. The assist grip 70 is connected to the middle board 10 at two front and rear positions, and is fixed to an inner panel of a door (not shown).

  A panel attachment hole 11 is provided below the assist grip 70 by opening the middle board 10. A switch panel (not shown) to which a switch for opening and closing the power window is attached can be attached to the panel attachment hole 11.

  An inside handle portion 80 having a handle cover 81 is provided above the front end connection portion of the assist grip 70. A handle cover attachment hole (not shown) is provided at a joint portion of the middle board 10 with the inside handle portion 80. A handle cover 81 is attached to the peripheral edge portion of the handle cover mounting hole.

  An upper base 20 is disposed above the middle board 10. The upper base 20 includes a cover member 21 mounted on the surface thereof, and a seat memory switch 22, for example, which is a functional product in the passenger compartment, is attached to the cover member 21. The seat memory switch 22 is connected to a control device (not shown) by a wire harness W. When the switch is pressed, data such as a seat position stored in advance for each passenger is read and read. This is a switch for moving the sheet based on the data.

  Now, the wire harness W connected to the seat memory switch 22 is provided on the back side of the trim material 1 and has a connector C connected to the main harness (not shown) of the vehicle at the tip thereof. It is fixed to the clamp 90. The clamp 90 is disposed at a position corresponding to the handle cover 81 on the back side of the middle board 10. Hereinafter, the mounting structure of the clamp 90 will be described with reference to the drawings of FIGS.

  The clamp 90 includes a fixing portion 91 that fixes the wire harness W, and a main body portion 92 that is inserted into the through hole 12 provided in the middle board 10. A pair of bending locking pieces (an example of the “locking portion” of the present invention) 93 is formed in a folded shape at the tip of the main body 92, and both the bending locking pieces 93 are inserted into the through holes 12. It is possible to bend in a direction crossing the direction. Further, a flange portion 94 that surrounds the middle board 10 in cooperation with the bending locking piece 93 and prevents rattling is provided at the end of the main body 92 opposite to the bending locking piece 93.

  On the other hand, the skin 40 covering the through-hole 12 is in a form bulged to the surface side with a sheet material made of a thermoplastic resin such as polypropylene. For this reason, the accommodating part 41 which connects with the inside of the through-hole 12 is formed in the part by which the skin 40 bulged. In the housing portion 41, the main body portion 92 can be inserted through the through hole 12, and in a state where the main body portion 92 is housed in the housing portion 41, the protruding end of the bending locking piece 93 is at the opening edge of the through hole 12. It is designed to be locked. For this reason, the main-body part 92 is hold | maintained at the inside of the accommodating part 41 in the securing state. Since the skin 40 covering the through hole 12 is in a position covered by the handle cover 81, the portion where the skin 40 protrudes to the surface side is not visible from the outside.

  The present invention has the structure as described above, and the operation thereof will be described subsequently. While fixing the wire harness W with the fixing | fixed part 91, the main-body part 92 is inserted toward the through-hole 12. As shown in FIG. When both the bending locking pieces 93 are bent and deformed toward the main body 92 by the inner wall of the through hole 12 and pass through the through hole 12, they are elastically restored and locked to the opening edge portion of the through hole 12, and at the flange portion 94, the middle. The opening edge on the back side of the board 10 is pressed. At this time, both the bending locking pieces 93 are in contact with the outer skin 40 and receive a slight reaction force from the side, but the protruding ends of the both bending locking pieces 93 are opened to the through holes 12. Since the middle board 10 can be clamped directly on the edge (the surface of the middle board 10) and in cooperation with the flange 94, the clamp 90 can be firmly fixed to the middle board 10.

  Next, a method for manufacturing the trim material 1 will be described with reference to FIG. First, the mold 100 used for manufacturing the trim material 1 will be briefly described. A plurality of suction holes 102 are opened on the molding surface 101 of the molding die 100 so that the skin 40 can be sucked to the surface of the middle board 10 through the middle board 10 set on the molding surface 101. It has become. A pin 103 protrudes from the molding surface 101 of the mold 100. The shape of the pin 103 is set so as to be able to be inserted into the through hole 12 and to conform to the bulging shape of the accommodating portion 41. That is, the protrusion height of the pin 103 from the molding surface 101 is set to a dimension that combines the depth dimension of the through hole 12 and the depth dimension of the accommodating portion 41.

Next, a method for manufacturing the trim material 1 using the mold 100 will be described. The manufacturing method of the trim material 1 includes a base material forming step, an adhesive application step, and a trim material forming step.
In the base material forming step, the middle board 10 provided with the through holes 12 is formed in advance. In the adhesive application process, an adhesive is applied to the surface of the middle board 10 by a spray gun or the like.
In the trim material forming step, the middle board 10 in which the through hole 12 is formed is placed on the forming surface 101 of the forming die 100 so that the through hole 12 is inserted through the pin 103. On the middle board 10, a heat-softened skin 40 having no through-holes is placed. When suction is performed through the suction holes 102, the skin 40 is sucked through the suction holes 102 and the vent holes 13 provided through the middle board 10, and is attached to the surface of the middle board 10. At this time, the skin 40 adheres to the periphery of the pin 103 protruding from the mold 100 and is shaped to form the accommodating portion 41. A gap S <b> 1 is formed at the opening edge of the through hole 12 due to the bending elasticity of the skin 40. Thereafter, by removing the middle board 10 from the mold 100, the middle board 10 to which the skin 40 is attached is obtained.

  According to such a manufacturing method, it is possible to omit the step of drilling the skin 40. In addition, in a state where the main body 92 is inserted into the through hole 12 and accommodated in the accommodating portion 41, the both bending locking pieces 93 enter the gap S1, and the protruding end of the both bending locking pieces 93 is the opening edge of the through hole 12. Therefore, the clamp 90 can be firmly fixed to the middle board 10.

<Embodiment 2>
Next, Embodiment 2 of the present invention will be described with reference to the drawing of FIG. The trim material 2 according to the present embodiment is obtained by partially changing the shape of the accommodating portion 41 according to the first embodiment.

  The accommodating part 42 of this embodiment is provided with the expansion space S2 formed by making the outer peripheral edge part of the through-hole 12 into the non-adhesive state between the skin 40 and the middle board 10. Although the clearance S1 is formed at the opening edge of the through hole 12 in the first embodiment, the expansion space S2 of the present embodiment is intentionally formed to be larger than the clearance S1 of the first embodiment. However, this is different from the first embodiment.

  That is, in the manufacturing process of the trim material 2, a masking sheet (not shown) is placed on the outer peripheral edge of the through hole 12 before applying the adhesive to the surface of the middle board 10. Then, by applying the adhesive to the surface of the middle board 10 and then removing the masking sheet, a non-adhesive region where the adhesive is not applied to the outer peripheral edge portion is formed in the through hole 12. When the skin 40 is laminated on the surface of the middle board 10 formed in this way and pasted, an expansion space S <b> 2 is formed at the outer peripheral edge of the through hole 12.

  According to the present embodiment, when the main body 92 is inserted into the through-hole 12 and accommodated in the accommodating portion 42, the both bending locking pieces 93 are accommodated in a non-contact state with the skin 40 inside the expansion space S2. For this reason, compared with Embodiment 1, the clamp 90 can reduce the reaction force received from the skin 40 corresponding to the opening edge part of the through-hole 12. FIG. Therefore, the clamp 90 can be more firmly fixed to the middle board 10.

<Embodiment 3>
Next, Embodiment 3 of the present invention will be described with reference to the drawing of FIG. The trim material 3 according to the present embodiment is obtained by partially changing the shape of the clamp 90 according to the first embodiment. The same components are denoted by the same reference numerals, and other common configurations, operations, and effects are provided. The description of is omitted.

The main body 111 includes a locking protrusion (an example of the “locking portion” in the present invention) 112 that protrudes laterally. The locking projection 112 is for locking to the opening edge of the through-hole 12 and holding the main body 111 inside the housing portion 43.

  The skin 40 constituting the housing portion 43 is pushed inward by the tip of the main body 111 while the main body 111 is being inserted into the through hole 12. That is, unlike the accommodating part 43 after the main body part 111 is accommodated, the accommodating part 43 before the main body part 111 is accommodated is expanded by pushing the main body part 111 even if it is not shaped. It has become.

  According to the present embodiment, the shape of the housing part 43 and the shape of the main body part 111 do not necessarily match, and even if the housing part 43 is formed in a state different from the normal size, the molding error is absorbed. Is possible.
