As such a decorative member, for example, an armrest cover described in Patent Document 1 below can be exemplified. In the thing of patent document 1, the vehicle front end side is provided with the armrest part (bulging part which bulges in the vehicle interior side) which makes a curved shape. The armrest cover of Patent Literature 1 has a shape corresponding to the curved shape of the armrest portion, a main body portion extending along the vehicle front-rear direction, and an extending portion extending from the vehicle front end portion of the main body portion toward the vehicle compartment outer side. (Terminal portion of the armrest cover). The extending portion extends along the vehicle front end surface of the armrest portion. Moreover, generally the attachment boss | hub is formed in the main-body part in such a decorating member. The decoration member is attached to the armrest portion by the attachment boss.

JP 2001-262935 A

  For example, the mounting boss as described above protrudes from the decorating member toward the outside of the passenger compartment. Thereby, a decorating member can be attached to an armrest part from the vehicle interior side. Further, in the decorative member, the extending portion extending along the vehicle front end surface is difficult to ensure the length in the vehicle front-rear direction. For this reason, it is difficult to form the mounting boss protruding toward the outside of the passenger compartment in the extended portion. Under such circumstances, it is difficult to attach the extended portion directly to the armrest portion. Therefore, the mounting boss is preferably formed at a location near the extended portion in the main body portion. By fixing the location close to the extending portion of the decorative member to the armrest portion, it is possible to suppress a situation in which the extended portion that is the terminal portion of the decorative member is displaced with respect to the armrest portion.

  However, it is difficult to form such an attachment boss close to the extended portion of the decorative member. The reason for this will be described with reference to FIG. FIG. 8 shows a configuration in which the decoration member 2 is attached to the armrest portion 3 using the attachment boss 1. In FIG. 8, the mounting boss 1 is formed on the back surface (surface outside the passenger compartment) of the main body 2 </ b> A of the decorating member 2. The tip of the mounting boss 1 is inserted into a through hole 3 </ b> A formed in the armrest portion 3. Then, the mounting boss 1 is fixed to the armrest portion 3 by attaching the screw 5 to the mounting boss 1 from the outside of the passenger compartment (upper side in FIG. 8).

  Here, when the mounting boss 1 is used, it is necessary to form the rib 6 around the mounting boss 1. For example, a plurality of ribs 6 are formed radially around the mounting boss 1. The rib 6 receives a load at the time of screwing when the screw 5 is screwed from the outside of the passenger compartment, and is a member for sandwiching the hole edge portion of the through hole 3A between the screw 5 and the rib 6. Is done. The distance L1 between the extending portion 2B of the decorative member 2 and the mounting boss 1 is increased by the amount of the rib 6.

  Further, when the decorative member 2 and the mounting boss 1 are integrally molded with a synthetic resin using a molding die, the diameter of the mounting boss 1 is directed toward the proximal end in order to die-cut the mounting boss 1. It needs to grow as you go. When the diameter of the base end side of the mounting boss 1 is increased, the distance between the extending portion 2B and the fixed portion (screw 5) is increased accordingly. In addition, although the structure which fastens a mounting boss | hub by heat caulking instead of using the screw | thread 5 is also known, even in such a case, the same problem (the distance of the mounting boss | hub 1 and the extension part 2B will be freed). Is a concern.

  From the above, in the configuration using the mounting boss, it is difficult to place the mounting boss close to the extended portion (terminal portion) of the decorative member, and positioning of the extended portion of the decorative member is difficult. There was a problem that there was.

  The present invention has been completed based on the above circumstances, and a vehicle capable of more reliably positioning the extending portion of the decorative member with respect to the bulging portion to which the decorative member is attached. The purpose is to provide a door trim.

In order to solve the above-described problems, the present invention provides a trim main body, a bulge provided on a surface of the trim main body on the vehicle interior side, bulged toward the vehicle interior, and attached to the bulge. A vehicle door trim including a decoration member, wherein the decoration member extends in a vehicle front-rear direction, and is arranged along a vehicle interior side surface of the bulging portion; An extending portion that extends from one end in the extending direction of the decorative member main body portion toward the outside of the passenger compartment and is disposed along the vehicle front end surface or the vehicle rear end surface in the bulging portion, and the bulging portion Is formed with a through-hole penetrating along a substantially vertical direction, and is inserted into the through-hole at a location near the extension portion on the surface of the decorative member main body on the outer side of the passenger compartment. Projecting pieces projecting outward from the passenger compartment, and the projecting pieces The tip of the projecting piece that protrudes in a direction intersecting the through direction of the hole and that is displaced in the vehicle front-rear direction by the inner peripheral surface of the through hole is inserted from above into the through hole. Is disposed below the edge of the through hole, and the protruding piece includes a base end portion extending from a surface of the decorating member main body portion outside the vehicle compartment, and a vehicle from the base end portion. An intermediate portion that extends to the outside of the vehicle and is inclined with respect to the base end portion and that is inclined downward toward the outside of the vehicle compartment; and the distal end portion that extends from the intermediate portion to the outside of the vehicle compartment; It is characterized by being penetrated in the direction and having the intermediate portion inserted through the through hole .

  According to this invention, when attaching a decorating member with respect to a bulging part, the position shift of the decorating member with respect to a bulging part can be controlled by inserting a protruding piece in a through-hole. Specifically, the positional deviation of the projecting piece in the vehicle front-rear direction, and thus the decorative member, can be regulated by the inner peripheral surface of the through hole. Moreover, since the front-end | tip part of a protrusion piece is distribute | arranged below the hole edge part of a through-hole, it can control by a hole edge part that a protrusion piece displaces upwards. Thereby, the situation where a decorating member floats (separates) with respect to a bulging part can be suppressed.

  As described above, in the present invention, the decorative member can be positioned with respect to the bulging portion by inserting the protruding piece into the through hole. If the projecting piece is used, it is not necessary to provide the receiving ribs required when using the mounting boss, so that the projecting piece can be arranged closer to the extended portion. . As a result, the extended portion can be more reliably positioned with respect to the bulging portion.

  The said structure WHEREIN: The said protrusion piece shall be formed in the edge part by the side of the said extension part in the said main-body part.

  If it is set as such a structure, the part near the extension part in a decorating member can be positioned with respect to a bulging part.

  The protruding piece may be formed integrally with the main body portion and formed at one end portion of the main body portion in the vertical direction.

  With such a configuration, if the main body and the projecting piece are integrally formed using a molding die, for example, the projecting piece is provided at the center in the vertical direction of the main body. The undercut portion can be reduced as compared with the configuration. Thereby, a main-body part and a protrusion piece can be easily shape | molded with a shaping | molding die.

  ADVANTAGE OF THE INVENTION According to this invention, the vehicle door trim which can position the extended part of a decorating member more reliably with respect to the bulging part which is the attachment object of a decorating member can be provided.
