Description

[Technical Field]

[0001] The technology disclosed herein relates to vehicle door trim. [Background technology]

[0002] Conventionally, a vehicle door trim equipped with a pull handle is known, for example, from the following Patent Document 1. The pull handle (pull handle box) of the door trim in Patent Document 1 is box-shaped with a recessed portion that opens upward, and an occupant can insert their fingers into the recessed portion and grip it to open or close the vehicle door.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-195340 Summary of the Invention [Problem to be solved by the invention]

[0004] When manufacturing a pull handle by injection molding, the pull handle is divided into multiple components and each component is molded separately, which makes it possible to manufacture pull handles with more complex shapes based on designs, etc. However, when a pull handle is divided into multiple components, its rigidity tends to be lower than when it is formed as a single unit.

[0005] In particular, when the pull handle is divided into compartments, there is a concern that a high load will be applied to the parting line, which is the boundary between the two components, when the pull handle is gripped to close the vehicle door, and that one or both components will be deformed. If such deformation occurs, a gap will form between the two components at the parting line, which may degrade the design.

[0006] Furthermore, when the pull handle is attached to the door trim using a fastening structure such as bolts and nuts or heat caulking, the fastening is performed perpendicular to the plate surface of the door trim, but due to the constraints of such an attachment direction, the fastening point may be positioned slightly away from the parting line, which can lead to a problem of a gap being more likely to occur at the parting line.

[0007] The technology disclosed in this specification was developed based on the above circumstances, and aims to increase the rigidity of a pull handle in a vehicle door trim that has a split-structured pull handle. [Means for solving the problem]

[0008] The technology disclosed in this specification, which has been completed to solve the above-mentioned problems, is a vehicle door trim in which a pull handle having a recessed portion that opens upward is attached to a trim board that constitutes the interior surface of a vehicle door, the pull handle being configured by assembling an inner member having an inner wall portion that is disposed on the interior side of the vehicle among the wall portions that constitute the recess, and an outer member having an outer wall portion that is disposed on the exterior side of the vehicle among the wall portions that constitute the recess, the inner member and the outer member being configured by assembling an inner extension portion that is provided on at least a part of a peripheral end of the inner member and extends outward from the recess, and an outer extension portion that is provided on at least a part of a peripheral end of the outer member and extends outward from the recess. and an extension portion, which are overlapped to form an overlapping portion, the overlapping portion including a first overlapping portion that is overlapped on the trim board and fastened integrally to the trim board by a fastening portion, and a second overlapping portion that is arranged at a position closer to the parting portion between the inner member and the outer member in the recess than the fastening portion and extends in a direction intersecting the plate surface of the trim board, the second overlapping portion being provided with a locking portion that locks a locking protrusion provided on one of the inner member and the outer member into a locking hole provided on the other, and the locking portion can be locked by the locking protrusion or the locking hole moving relatively along the fastening direction of the fastening portion.

[0009] According to the above configuration, even if the fastening portion (first overlapping portion) for holding the inner member and the outer member in an assembled state and attaching them to the trim board is located slightly away from the parting line due to restrictions on the attachment direction to the trim board, the locking portion for locking the inner member and the outer member together is provided in the second overlapping portion, which is closer to the parting line, thereby increasing the rigidity of the pull handle. In other words, it is possible to prevent a situation in which at least one of the members is deformed by a force applied toward the inside of the vehicle cabin when the pull handle is used, causing a gap to form at the parting line.

[0010] Furthermore, when the inner and outer members are attached to the trim board in order, they are attached close to each other in the fastening direction of the fastening parts, but because the locking parts can be locked by the locking projections or locking holes moving relatively in the fastening direction, the outer member can be locked to the trim board and inner member at the same time as they are attached to the trim board and inner member. Therefore, providing the locking parts does not increase the number of steps during assembly, and there is no need to secure work space for locking the locking parts.

[0011] Note that the recessed portion that is open upward in the present technology may include a recessed portion that is open obliquely upward as long as it includes an upward portion.

[0012] The fastening portion and the locking portion may be provided side by side in the fore-and-aft direction of the vehicle at an upper end of the opening of the recess on the rear side of the vehicle. With this configuration, the fastening portion and the locking portion are provided side by side at positions where the greatest force is likely to be applied, making it easier to obtain the effects of the present technology.

[0013] The inner wall portion may include a finger hook portion 33A that bulges outward from the vehicle cabin along the opening edge of the recess, and a standing wall extending toward the vehicle cabin interior may be provided at the rear end of the finger hook portion 33A, and the locking protrusion may be provided on the standing wall. With this configuration, the second overlapping portion and the locking portion can be provided by utilizing the finger hook portion 33A.

[0014] The outer member may be fixed to a door panel disposed on the outer side of the trim board. With this configuration, when a force toward the inside of the vehicle cabin is applied to the pull handle, the inner member is more likely to deform because the outer member is fixed to the door panel, and the effect of the locking portion of the present technology is more effective. [Effects of the Invention]

[0015] According to the technology disclosed in this specification, it is possible to increase the rigidity of a pull handle in a vehicle door trim that includes a pull handle configured in segments. [Brief explanation of the drawings]

[0017] An embodiment will be described in detail with reference to Figures 1 to 13. In the drawings, the arrows FR and RR indicate the front and rear of the vehicle (the direction of travel of the vehicle), the arrows IN and OUT indicate the inside and outside of the vehicle cabin, and the arrows UP and DW indicate the top and bottom of the vehicle. These directions all refer to the state in which the pull handle 30 is attached to the trim board 11 of the vehicle door trim 10.

[0018] FIG. 1 is a perspective view of a vehicle door trim 10 as viewed from inside the vehicle cabin. The door trim 10 is mainly composed of a generally plate-shaped trim board 11, which is generally composed of an upper trim 11A and a lower trim 11B. Of these, the lower trim 11B is composed by assembling a plurality of plate-shaped members together. Functional parts are attached to the plate-shaped members, or functional parts are composed of several plate-shaped members combined together. The upper trim 11A and the lower trim 11B are basically made of an electrically insulating synthetic resin material such as polypropylene, and are covered, as necessary, with a skin material or the like to enhance the texture and feel.

[0019] An armrest 20 that extends in the front-to-rear direction of the vehicle and bulges into the passenger compartment is provided between the upper end of the lower trim 11B and the lower end of the upper trim 11A, on the outer side of the passenger compartment. More specifically, the armrest 20 is provided between the upper end of a bulging portion 12 that bulges into the passenger compartment at the upper part of the lower trim 11B and the lower end of the upper trim 11A, and includes an armrest surface portion 21 located on the rear side of the vehicle and extending in a substantially horizontal direction, an inclined surface portion 22 that is connected to the front side of the armrest surface portion 21 and slopes upward, and a horizontal surface portion 23 that is connected to the front side of the inclined surface portion 22 and extends in a substantially horizontal direction.

[0020] Of these, armrest surface 21 is composed of armrest surface member 25 having a plate surface extending in a substantially horizontal direction, and its surface (upper surface, interior surface) is covered with a cushioned covering (not shown). Inclined surface 22 and horizontal surface 23 are composed of arm front member 26, and horizontal surface 23 is provided with switch base 24 on which various operation switches are arranged side by side. Inclined surface 22 (between armrest surface 21 and switch base 24) is provided with pull handle 30 that opens diagonally upward (rearward) so that an occupant can insert their hand when opening or closing the vehicle door from inside the vehicle compartment.

[0021] The pull handle 30 is made of synthetic resin, such as a thermoplastic resin such as polypropylene or polyethylene. The pull handle 30 has a recess 31 recessed from the inclined surface 22 so that a passenger can insert their hand. The recess 31 is box-shaped and opens diagonally upward (rearward). The recess 31 is formed by combining an inner member 32 arranged inside the passenger compartment and an outer member 51 arranged outside the passenger compartment relative to the inner member 32 (see FIGS. 2 and 6).

[0022] 6 and 7, the inner member 32 is formed in a bent plate shape on the outer side of the lower trim 11B (bulge 12) and opens toward the outside of the vehicle cabin, and includes an inner wall portion 33 located on the inner side of the recess 31 of the pull handle 30 and extending along the plate surface of the lower trim 11B, a bottom wall portion 34 extending substantially horizontally from the lower end of the inner wall portion 33 toward the outside of the vehicle cabin and forming the bottom surface of the recess 31, a sloping lower front wall portion 35 rising forward and upward from the front end of the bottom wall portion 34, and a sloping upper front wall portion 36 rising rearward and upward from the upper end of the lower front wall portion 35. The bottom wall portion 34 is trapezoidal, has two sides extending along the plate surface of the trim board 11, and has a rear end that tapers toward the inside of the vehicle cabin. The upper front wall portion 36 extends in a direction that intersects substantially perpendicularly with the inclined surface portion 22 of the armrest 20 described above.

[0023] The upper portion of the inner wall 33 along the opening of the recess 31 forms a finger hook 33A that bulges outward from the vehicle cabin (toward the inside of the recess 31) compared to the lower portion. Since the inner wall 33 has the finger hook 33A in this manner, when an occupant inserts their hand into the recess 31, they can hook their fingers from below on the finger hook 33A and easily grip the upper portion of the pull handle 30.

[0024] On the other hand, the outer member 51 has a bent plate shape that can close the space surrounded by the inner member 32 from the outside of the vehicle cabin to form the recess 31 between itself and the inner member 32. As shown in Figures 6 and 8 , the outer member 51 includes an outer wall portion 52 disposed opposite the inner wall portion 33 of the inner member 32, and a rear wall portion 54 that rises from the rear end of the outer wall portion 52 toward the inside of the vehicle cabin and diagonally rearward. In other words, the recess 31 is a concave space portion surrounded by the inner wall portion 33, bottom wall portion 34, lower front wall portion 35, and upper front wall portion 36 of the inner member 32, and the outer wall portion 52 and rear wall portion 54 of the outer member 51.

[0025] The outer wall 52 has a panel fixing hole 53 near the upper end of its central portion in the vehicle front-rear direction, through which a bolt for fixing the outer member 51 and the armrest surface member 25 to a door panel (not shown) is inserted. FIG. 4 is a perspective view showing the pull handle 30 and the armrest surface member 25 assembled to the lower trim 11B, with the panel fixing hole 25A of the armrest surface member 25 aligned with the panel fixing hole 53. As shown in FIG. 4 and FIG. 8, the outer surface of the vehicle interior of the outer member 51 has multiple mounting bosses 71, 72, and 73 for attaching the armrest surface member 25. The armrest surface member 25 has bolt insertion holes 25B, 25C, and 25D at corresponding positions. The armrest surface member 25 also has a boss insertion hole 25E through which the mounting boss 15 protruding from the lower trim 11B is inserted. In this manner, the armrest surface member 25 is integrally attached to the rear side of the pull handle 30.

[0026] As shown in FIGS. 6 and 7 , the peripheral edge of the inner member 32, other than the opening of the recess 31, is provided with an inner extension 37 extending outward from the recess 31. More specifically, the rear end of the inner wall 33 is provided with an inner standing wall 38 (an example of an inner extension, an example of a part of the second overlapping portion) that rises from the rear end toward the interior of the vehicle and extends in a direction intersecting with the plate surface of the lower trim 11B at a substantially perpendicular direction to the plate surface of the lower trim 11B or at a slight incline relative to the plate surface of the lower trim 11B so as to approach the plate surface from the front side of the vehicle. The inner standing wall 38 is shaped to close the gap between the rear end of the finger hook 33A and the trim board 11 when the inner member 32 is attached to the trim board 11.

[0027] Furthermore, a flange-shaped flange portion 39 (an example of an inner extending portion and an example of a part of the first overlapping portion) is provided on a peripheral end portion of the inner member 32 other than the opening of the recess 31, protruding outward from the recess 31 and extending along the plate surface of the lower trim 11B. In the portion of the peripheral end portion of the inner member 32 where the inner standing wall 38 is provided, this flange portion 39 protrudes from the end of the inner standing wall 38 on the cabin side toward the outside of the recess 31. In other words, the flange portion 39 is provided in a form that is integrally connected to the end portion of the inner standing wall 38.

[0028] 6 and 8, an outer extending portion 56 is provided on the peripheral edge of the outer member 51 at a portion other than the opening of the recess 31, and extends outward from the recess 31. Most of the outer extending portion 56 extends in a direction along the plate surface of the outer member 51. More specifically, the portion of the outer extending portion 56 other than the portion extending from the rear end of the rear wall portion 54 extends in a direction along the plate surface of the outer member 51.

[0029] The outer extending portion 56 extends from the rear end of the rear wall portion 54 and is provided with an outer standing wall 57 (an example of an outer extending portion, an example of a part of a second overlapping portion) that overlaps the inner standing wall 38 from the outside of the vehicle compartment at a portion that corresponds to the inner standing wall 38 when the outer member 51 is combined with the inner member 32. In other words, the outer standing wall 57 extends in a direction that intersects with the plate surface of the lower trim 11B.

[0030] Furthermore, the portion of the outer extension 56 that extends from the rear end of the rear wall 54, other than the portion from which the outer standing wall 57 extends, extends in a flange-like shape along the plate surface of the lower trim 11B. Hereinafter, this portion extending along the plate surface of the lower trim 11B will be referred to as an outer rear end extension 58 (an example of an outer extension portion, an example of a portion of the first overlapping portion). The outer rear end extension 58 is a portion that overlaps with a portion of the flange 39 of the inner member 32 (the portion extending from the inner wall 33). The outer rear end extension 58 is not continuous with the end of the outer standing wall 57 facing the interior of the vehicle. In other words, the end of the outer standing wall 57 facing the interior of the vehicle constitutes a portion of the peripheral edge of the outer member 51.

[0031] Of the outer extension portion 56, the portion that extends forward of the outer wall portion 52 is an extension frame portion 59 that extends forward in a frame-like shape, and the upper portion of this extension frame portion 59, together with the lower trim 11B and the upper front wall portion 36 of the inner member 32, forms an attachment portion for attaching the switch base 24 (arm front member 26).

[0032] With this configuration, when the inner member 32 and the outer member 51 are properly positioned relative to the trim board 11, the inner member 32 and the outer member 51 form the recess 31 of the pull handle 30. In addition, the inner extension 37 and a portion of the outer extension 56 overlap each other to form an overlapping portion 50.

[0033] 6 to 8, the flange portion 39 of the inner extension portion 37 is provided with locking claws 40, 41 protruding toward the outside of the vehicle cabin at a portion continuous with the bottom wall portion 34 and a portion continuous with the lower front wall portion 35, and the outer extension portion 56 is provided with locking holes 60, 61 for locking the locking claws 40, 41 at a portion facing the locking claws 40, 41. The flange portion 39 of the inner extension portion 37 is provided with positioning protrusions 42, 43 protruding toward the outside of the vehicle cabin at a portion continuous with the rear of the inner wall portion 33 and a portion continuous with the outside of the vehicle cabin of the upper front wall portion 36, and the outer extension portion 56 is provided with positioning holes 62, 63 for fitting the positioning protrusions 42, 43 therein at a portion facing the positioning protrusions 42, 43. The outer member 51 is attached to the inner member 32 in the correct orientation and can be held together by the engagement of the locking claws 40, 41 and the locking holes 60, 61 and the positioning by the positioning protrusions 42, 43 and the positioning holes 62, 63. The direction in which the locking claws 40, 41 engage with the locking holes 60, 61 and the direction in which the positioning protrusions 42, 43 are inserted into the positioning holes 62, 63 are both along the direction between the interior and exterior of the vehicle (the vehicle width direction).

[0034] Furthermore, boss insertion holes 44, 45, 64, 65 are provided near the upper ends (near the opening of the recess 31, first overlapping portion 50A) on the front and rear sides of the inner extending portion 37 and the outer extending portion 56, respectively, for collectively inserting the mounting bosses 14, 15 protruding from the lower trim 11B toward the outside of the vehicle cabin. Furthermore, boss insertion holes 46, 47, 66, 67 are provided near the lower ends (front and rear sides) of the inner extending portion 37 and the outer extending portion 56, respectively, for collectively inserting the mounting bosses 16, 17 (see FIG. 2) protruding from the lower trim 11B toward the outside of the vehicle cabin. Furthermore, a boss insertion hole 68 is provided at the upper end of the front side of the extension frame portion 59 for inserting the mounting boss 18 protruding from the lower trim 11B toward the outside of the vehicle cabin, and a locking hole 69 is provided at the lower part of the front side for locking the locking claw 19 protruding from the lower trim 11B toward the outside of the vehicle cabin (see Figure 3).

[0035] The inner member 32 and the outer member 51 are attached to the lower trim 11B in the correct orientation and held together by the fastening (fastening portions) of these mounting bosses 14, 15, 16, 17, and 18 and the locking of the locking claws 19. The insertion direction of the mounting bosses 14, 15, 16, 17, and 18 into the boss insertion holes 44, 45, 46, 47, 64, 65, 66, 67, and 68, i.e., the fastening direction of the mounting bosses 14, 15, 16, 17, and 18, and the locking direction of the locking claws 19 into the locking holes 69, are all oriented along the interior and exterior of the vehicle (vehicle width direction).

[0036] Note that "fastening" refers to joining three or two components by inserting mounting bosses 14, 15, 16, 17, and 18 into boss insertion holes 44, 45, 46, 47, 64, 65, 66, 67, and 68 and fastening inner member 32 and outer member 51 to lower trim 11B. Specific fastening methods include fastening bolts and nuts to mounting bosses 14, 15, 16, 17, and 18, or heat caulking mounting bosses 14, 15, 16, 17, and 18 to form fastened portions.

[0037] However, when the pull handle 30 (recess 31) is formed by combining the inner member 32 and the outer member 51, the rigidity of the pull handle 30 tends to be lower than when the pull handle 30 is integrally formed. Specifically, when an occupant operates the pull handle 30, a load (load acting in the interior / exterior direction of the vehicle) tends to act near the boundary between the inner member 32 and the outer member 51, potentially deforming one or both members. In particular, when a force acts toward the interior of the vehicle, a gap may form at the boundary between the two members, potentially degrading the design. Such a gap is likely to occur at the boundary, particularly behind the opening of the recess 31, where a large force is likely to act. Furthermore, the fastening portion (the portion where the mounting bosses 14, 15, 16, 17, and 18 are provided) for attaching the inner member 32 and the outer member 51 to the lower trim 11B collectively is sometimes positioned somewhat away from the boundary because its mounting direction (fastening direction) is restricted to the interior / exterior direction of the vehicle. In such a case, gaps are more likely to occur.

[0038] Therefore, in this embodiment, a locking portion 80 that locks the inner member 32 and the outer member 51 to each other so as to restrict movement of the inner member 32 and the outer member 51 in the interior and exterior directions of the vehicle is provided at a position on the rear side of the opening of the recess 31 of the parting portion, which is particularly likely to be subjected to a large force, and which is closer to the recess 31 than the fastening portion (mounting boss 15), i.e., at a portion (referred to as second overlapping portion 50B) where the inner standing wall 38 and the outer standing wall 57 overlap and which is adjacent to the parting portion on the rear side of the opening of the recess 31. Specifically, a locking protrusion 81 that protrudes toward the rear of the vehicle is provided on the outer surface (rear surface) of the vehicle interior of the inner standing wall 38, and a locking hole 85 that locks the locking protrusion 81 is provided on the outer surface (rear surface) of the vehicle interior of the outer standing wall 57 at a position that faces the locking protrusion 81 when the outer member 51 is attached to the inner member 32.

[0039] 9 and 10, the locking projection 81 is configured such that three plate-like ribs 82 are arranged vertically on the rear surface of the inner standing wall 38 with their plate surfaces facing up and down. Each rib 82 has a guide surface 83, which is an end surface that rises obliquely from the outside of the vehicle compartment toward the inside of the vehicle compartment. The end surfaces on the inside of the vehicle compartment of each rib 82 are connected to each other to form a locking surface 84, which has a plate surface that conforms to the lower trim 11B. The locking surface 84 rises nearly perpendicularly from the inner standing wall 38.

[0040] On the other hand, the locking hole 85 is a rectangular hole that can penetrate at a position corresponding to the locking protrusion 81 and allow the locking protrusion 81 to be fitted in when the outer standing wall 57 is overlapped on the inner standing wall 38.

[0041] In this way, the locking portion 80, which is composed of the locking protrusion 81 and the locking hole 85, is arranged side by side in the fore-and-aft direction of the vehicle adjacent to the above-mentioned fastening portion (mounting boss 15 and boss insertion holes 45, 65) on the rear side of the opening of the recess 31 (see Figure 3).

[0042] The pull handle 30 of this embodiment configured as described above is formed as follows. First, the mounting bosses 14, 15, 16, and 17 of the lower trim 11B are inserted into the boss insertion holes 44, 45, 46, and 47 of the inner member 32, thereby positioning the inner member 32 relative to the lower trim 11B. Next, the mounting bosses 14, 15, 16, 17, and 18 of the lower trim 11B are inserted into the boss insertion holes 64, 65, 66, 67, and 68 of the outer member 51. Furthermore, the positioning protrusions 42 and 43 of the inner member 32 are inserted into the positioning holes 62 and 63 of the outer member 51, thereby positioning the outer member 51 relative to the inner member 32 and the lower trim 11B, and the outer extension 56 is brought close to overlap the inner extension 37. As a result, the locking claws 40, 41 of the inner member 32 and the locking claw 19 of the lower trim 11B are inserted into the locking holes 60, 61, 69 of the outer member 51 and are locked to the edge portions of these holes.

[0043] 11 to 13, the cabin-side end of the outer standing wall 57 of the outer member 51 abuts against the locking protrusion 81 provided on the inner standing wall 38 of the inner member 32 from outside the cabin, and is gradually elastically deformed so as to open rearward by the guide surface 83 of the locking protrusion 81. Then, when the outer member 51 approaches the trim board 11 and the hole edge of the locking hole 85 passes over the cabin-side end (top) of the locking protrusion 81, the outer member 51 (outer standing wall 57) elastically returns to its original state, and the hole edge of the locking hole 85 locks with the locking surface 84 of the locking protrusion 81. The locking direction of the locking portion 80 is set in a direction that restricts movement of the inner member 32 and the outer member 51 in the cabin-outside direction. In other words, it is set in the same direction as the fastening direction of the fastening portion to the lower trim 11B.

[0044] This forms the overlapping portion 50, where the inner extension 37 and the outer extension 56 are overlapped. Thereafter, as shown in Figure 4, the armrest surface member 25 is attached to the lower trim 11B and the pull handle 30 at predetermined positions from outside the vehicle cabin, and the fastening portion is formed by fastening bolts or nuts to the mounting bosses 14, 15, 16, 17, 18, 71, 72, and 73 or by heat crimping. This completes the recess 31 of the pull handle 30, where the inner member 32 and the outer member 51 are fixed to the lower trim 11B.

[0045] Next, the effects will be described. The door trim 10 of this embodiment is a door trim 10 in which a pull handle 30 having a recess 31 that opens upward is attached to a trim board 11 that constitutes the interior surface of a vehicle door, and the pull handle 30 is configured by assembling an inner member 32 having an inner wall portion 33 that is disposed on the interior side of the vehicle among the wall portions that constitute the recess 31, and an outer member 51 having an outer wall portion 52 that is disposed on the exterior side of the vehicle among the wall portions that constitute the recess 31. The inner member 32 and the outer member 51 form an overlapping portion 50 in which an inner extension portion 37 that is provided on a part of the peripheral end of the inner member 32 and extends outward from the recess 31 and an outer extension portion 56 that is provided on a part of the peripheral end of the outer member 51 and extends outward from the recess 31 are overlapped. 0 includes a first overlapping portion 50A (flange portion 39 and outer rear end extension portion 58) that is overlapped on the lower trim 11B of the trim board 11 and fastened integrally to the lower trim 11B by a fastening portion, and a second overlapping portion 50B (inner standing wall 38 and outer standing wall 57) that is arranged at a position closer to the parting portion between the inner member 32 and the outer member 51 in the recess 31 than the fastening portion and extends in a direction intersecting the plate surface of the lower trim 11B, and the second overlapping portion 50B is provided with a locking portion 80 that locks a locking protrusion 81 provided on the inner member 32 into a locking hole 85 provided on the outer member 51, and the locking portion 80 can be locked by relative movement of the locking protrusion 81 or the locking hole 85 along the fastening direction of the fastening portion.

[0046] According to the above configuration, even if the fastening portion (first overlapping portion 50A) for holding the inner member 32 and the outer member 51 in an assembled state and for attaching them to the lower trim 11B is located slightly away from the parting line due to restrictions on the attachment direction to the lower trim 11B, the locking portion 80 for locking the inner member 32 and the outer member 51 to each other is provided in the second overlapping portion 50B, which is closer to the parting line, thereby increasing the rigidity of the pull handle 30. In other words, it is possible to prevent at least one of the members from deforming due to a force applied toward the inside of the vehicle cabin when the pull handle 30 is in use, and to prevent a gap from occurring at the parting line.

[0047] Furthermore, when the inner member 32 and the outer member 51 are attached to the lower trim 11B in that order, the members are attached by moving them close to each other in the fastening direction of the fastening parts (the direction in which the mounting bosses rise) so that the mounting bosses can be inserted into the boss insertion holes, but because the locking portions 80 can be locked by the relative movement of the locking projections 81 or the locking holes 85 in the fastening direction, they can be locked simultaneously with the attachment of the outer member 51 to the lower trim 11B and the inner member 32. Therefore, providing the locking portions 80 does not increase the number of steps during assembly, and there is no need to secure work space for locking the locking portions 80.

[0048] Furthermore, the fastening portion (mounting boss 15) and the locking portion 80 are provided side by side in the vehicle longitudinal direction at the upper end on the vehicle rear side of the opening of the recess 31. With this configuration, the fastening portion and the locking portion 80 are provided side by side at a position where the greatest force is likely to be applied, making it easier to obtain the effects of the present technology.

[0049] The inner wall 33 also has a finger hook 33A that bulges outward from the vehicle cabin along the opening edge of the recess 31, and an inner standing wall 38 that extends toward the inside of the vehicle cabin is provided at the rear end of the finger hook 33A, and a locking protrusion 81 is provided on the inner standing wall 38. With this configuration, the second overlapping portion and the locking portion 80 can be provided using the finger hook 33A.

[0050] Additionally, the outer member 51 is fixed to the door panel disposed on the outer side of the vehicle compartment of the lower trim 11B. With this configuration, when a force toward the inside of the vehicle compartment is applied to the pull handle 30, the inner member 32 is more likely to deform because the outer member 51 is fixed to the door panel, and the effect of the locking portion of the present technology is more effective.

[0051] <Other embodiments> The technology disclosed in this specification is not limited to the embodiments described above and illustrated in the drawings, and the following embodiments, for example, are also included in the technical scope.

[0052] (1) In the above embodiment, a method is illustrated in which the inner member 32 and the outer member 51 are attached individually and sequentially to the trim board 11. However, the inner member and the outer member may be first assembled and then attached to the trim board all at once.

[0053] (2) In the above embodiment, the pull handle 30 opens obliquely upward (rearward), but the pull handle may also open upward on an armrest extending horizontally.

[0054] (3) In the above embodiment, the locking portion 80 is provided on the vertical wall provided at the rear end of the finger hook 33A, but the location of the locking portion is not limited to the above embodiment. In addition, the locking portion does not necessarily have to be provided next to the fastening portion.

[0055] (4) The technical scope also includes a configuration in which the outer member is not fixed to the door panel. [Explanation of symbols]
