The door trim 11 includes a plate-like trim board 20 (board member). The trim board 20 is configured, for example, by molding a synthetic resin material or a material obtained by mixing natural fibers (such as kenaf) into a synthetic resin material into a plate shape.

  As shown in FIG. 1, the armrest 14 is formed on the trim board 20 so as to protrude to the front side (vehicle compartment side). The trim board 20 is provided with an inside door handle 15, a speaker 16, a pull handle 17, and the like. A skin material (not shown) is affixed so as to cover the surface of the trim board 20 on the vehicle interior side.

  As shown in FIG. 2, the trim board 20 includes a main wall portion 27 having a main surface 27 </ b> A facing the vehicle interior side, and an upper wall portion 28 extending from the upper end of the main wall portion 27 toward the vehicle interior outside. ing. Further, the upper surface 28 </ b> A of the upper wall portion 28 constitutes the upper surface of the door trim 11.

  In addition, as shown in FIG. 3, the connection location of the main wall part 27 and the upper wall part 28 has comprised the shape which curves in sectional view. That is, as shown in FIG. 2, the upper portion of the trim board 20 has a shape that curves outward (to the right in FIG. 2) toward the upper side.

  In the upper wall portion 28, a step portion 21 is formed at an end portion outside the vehicle compartment. That is, the stepped portion 21 is formed at a location on the trim board 20 (and thus the door trim 11) that is an upper portion and an end portion outside the passenger compartment.

  As shown in FIG. 1, the stepped portion 21 has a shape that is long in the vehicle front-rear direction, and is formed on the rear side of the trim board 20 (and thus the door trim 11) from the center in the vehicle front-rear direction.

  As shown in FIG. 2, the stepped portion 21 is formed by lowering the surface of the end portion outside the passenger compartment (the bottom surface 22 of the stepped portion 21) on the upper surface 28 </ b> A of the upper wall portion 28. That is, the stepped portion 21 is formed integrally with the trim board 20 and has a stepped shape in which the outside of the vehicle compartment is lower than the vehicle interior side.

  As shown in FIG. 2, the bottom surface 22 of the stepped portion 21 is an inclined surface that inclines downward as it goes toward the outside of the passenger compartment. Further, in the stepped portion 21, the side surface 23 that connects the upper surface 28 </ b> A and the bottom surface 22 is disposed so as to face the window glass 18. As described above, the step portion 21 is formed so as to be opened upward and on the vehicle interior side, and the occupant can insert a hand into the space (gap) formed by the bottom surface 22 and the side surface 23. It has a configuration.

  In the trim board 20, an extending portion 25 extending downward is formed below the step portion 21. A weather strip 40 extending in the vehicle front-rear direction is attached to the attachment hole 26 formed in the extending portion 25. The front end portion 41 of the weather strip 40 is in close contact with the window glass 18 so that the space between the window glass 18 and the trim board 20 is sealed.

  Further, the upper end P2 of the front end portion 41 of the weather strip 40 is arranged to be lower than the upper end P1 of the side surface 23 of the step portion 21 (corner portion of the step portion 21). Thereby, when the door trim 11 is viewed from the vehicle interior side (front view), the tip end portion 41 of the weather strip 40 is concealed by the trim board 20, and the design can be further improved.

  In other words, by providing the step portion 21, the mounting hole 26 is formed at a low position, and as a result, the upper end P <b> 2 of the weather strip 40 is easily disposed at a position lower than the upper end P <b> 1 of the side surface 23 of the step portion 21. It has a configuration.

  Next, an example of the forming die 50 for forming (manufacturing) the trim board 20 will be described with reference to the drawing of FIG. As shown in FIG. 3, the forming die 50 includes a lower die 51, an upper die 52, and a slide die 53.

  A molding surface 51A of the lower mold 51 (a surface facing the upper mold 52) has a shape that follows the outer surface of the cabin (for example, the surface of the extended portion 25) in the trim board 20. The lower mold 51 has a step portion 51 </ b> D for forming the step portion 21 of the trim board 20. The step portion 51D has a forming surface 51B for forming the bottom surface 22 of the step portion 21 and a forming surface 51C for forming the side surface 23 of the step portion 21.

  The upper mold 52 is disposed above the lower mold 51, and the lower mold 51 and the upper mold 52 (a pair of molds) are provided so as to be openable and closable by a driving device (not shown) (for example, a hydraulic cylinder). It has been. The molding surface 52A of the upper mold 52 has a shape that follows the main surface 27A and the upper surface 28A of the trim board 20.

  The slide mold 53 can be moved back and forth in the horizontal direction (left and right direction in FIG. 3) by a driving device (not shown) (for example, a hydraulic cylinder), and has a molding surface 53A that has a shape that follows the back surface of the trim board 20. doing.

  The molding die 50 of the present embodiment is configured such that a cavity C (molding space) can be formed by the molding surface 51A of the lower die 51, the molding surface 52A of the upper die 52, and the molding surface 53A of the slide die 53. And the shaping | molding die 50 is provided with the injection apparatus (not shown), and becomes a structure which can inject | pour the molten thermoplastic resin to the cavity C with an injection apparatus. And the trim board 20 which has the level | step-difference part 21 has a structure which can be shape | molded because the thermoplastic resin with which the cavity C was filled is cooled and solidified.

  Next, the effect of this embodiment will be described. In the present embodiment, the occupant can grip the stepped portion 21 by inserting a hand into the gap formed by the bottom surface 22 and the side surface 23 in the stepped portion 21. Thereby, when opening and closing the vehicle door 10, the vehicle door 10 can be hold | maintained. That is, the step portion 21 is a grip portion that can be gripped by the occupant.

  The occupant can also hold the posture by gripping the stepped portion 21. The step portion 21 is formed integrally with the trim board 20. Thereby, compared with the structure which provides the level | step-difference part 21 with another component, a number of parts can be reduced.

  By the way, as a holding part for a passenger | crew to hold | grip, as shown in FIG. 4, the structure which forms the recessed part 6 opened upwards in the upper wall part 5A of the trim board 5 instead of the level | step-difference part 21 is also considered.

  However, the depth direction (left-right direction in FIG. 4) of such a recess 6 is substantially perpendicular to the movable direction of the upper mold 2 (up-down direction in FIG. 4). That is, the recessed part 6 becomes an undercut part. For this reason, in order to mold the recess 6 with a mold, for example, a mold that is movable in the depth direction of the recess 6 (left-right direction in FIG. 4) is required. For this reason, apart from the molding die (lower die 1, upper die 2, slide die 3) for shaping other surfaces of the trim board 20, a dedicated slide die 4 for forming the recess 6 is necessary. The mold structure is complicated.

  In this regard, the stepped portion 21 of the present embodiment is formed at the end of the upper wall portion 28 on the outer side of the passenger compartment, and has a stepped shape in which the outer side of the passenger compartment is lower than the inner side of the passenger compartment. For this reason, when the step part 21 of the present embodiment is formed by a mold, as shown in FIG. 3, a mold for molding the outer surface of the trim board 20 (the surface of the extended portion 25). The step portion 21 can be formed by the (lower mold 51). Thereby, compared with the structure which made the holding part the recessed part 6, for example, a slide type | mold (corresponding to the slide type | mold 4 of FIG. 4) can be reduced, and a type | mold structure can be made a simpler structure.

  Further, the bottom surface 22 of the stepped portion 21 is an inclined surface that inclines downward as it goes to the outside of the passenger compartment. For this reason, at the time of shaping | molding by the shaping | molding die 50, the bottom face 22 of the level | step-difference part 21 turns into an inclined surface which goes away from the shaping | molding surface 51B as it goes below the FIG. For this reason, when the trim board 20 is removed from the lower mold 51, the mold can be easily removed.

  Further, the step portion 21 is formed in the door trim 11 at a location that is the rear portion of the vehicle rather than the center in the vehicle front-rear direction.

  The step portion 21 is formed at the rear portion of the door trim 11, that is, at the end opposite to the center of rotation of the vehicle door 10 when the vehicle door 10 is opened and closed, so that the step portion 21 is opened and closed when the vehicle door 10 is opened and closed. It becomes easy to grip.
