Has been. A door inner seal 25 (see FIG. 8) is attached to the flange 24.

  The first and second guide portions 80R and 80F each include a guide plate 81 and a pair of front and rear ribs 82 and 83. The guide plate 81 is a flat plate extending downward from the back surface 22 of the curved waist portion 23 in the door lining 20, and the plate surface is generally along the upper edge 21 a (see FIG. 8) of the handle opening 21. For this reason, as shown in FIG. 8, a predetermined space Sp is formed between the back surface 22 of the waist portion 23 and the guide portions 80R and 80F. This space Sp serves as a guide groove that is open at the bottom.

  The pair of front and rear ribs 82 and 83 are formed of flat vertical plates perpendicular to the guide plate 81, and are integrally formed on the front and rear sides of the guide plate 81, respectively. The pair of ribs 82 and 83 of the first guide portion 80R arranged on the rear side are notched at the bottom. On the other hand, in the second guide portion 80F arranged on the front side, the lower side of the rear rib 82 is notched, but the front rib 83 is not notched.

  FIG. 10 is a view of the handle case shown in FIG. 7 to 10, the handle case 42 has a pair of front and rear guided portions 43R and 43F extending upward from the upper end portion and a pair of front and rear attached portions 44 and 44 extending downward from the lower end portion. is doing. Here, in the handle case 42, the rear guided portion 43R is referred to as a first guided portion 43R, and the front guided portion 43F is referred to as a second guided portion 43F. The first and second guided portions 43R and 43F are flat plate-like members facing the waist portion 23, and their upper ends are formed in a flange shape extending toward the guide plate 81 as necessary.

  As shown in FIGS. 8 and 9, when the handle case 42 is attached to the handle opening 21, the handle case 42 is placed along the back surface 22 of the door lining 20, for example, from the rear to the handle opening 21. When slid forward, the pair of front and rear guided portions 43R and 43F are guided by the guide portions 80R and 80F.

  More specifically, when the handle case 42 is slid forward, the second guided portion 43F passes through the space Sp (guide groove Sp) on the back side of the first guide portion 80R, and then the first guide portion 80F. It is inserted into the space Sp (guide groove Sp) on the back side. The second guided portion 43F is inserted into the space Sp on the back side of the first guide portion 80R. If the handle case 42 is further slid forward, the first and second guided portions 43R and 43F are guided forward by the first and second guide portions 80R and 80F. The groove width of the guide groove Sp is set such that the first and second guided portions 43R and 43F can smoothly slide in the front-rear direction and there is no backlash.

  By the way, as described above, in the second guide portion 80F arranged on the front side, the rear rib 82 is notched, but the front rib 83 is not notched. This will be further described. Here, the front-side rib 83 in the second guide portion 80F will be described as “positioning stopper 83” as appropriate.

  FIG. 11 is a view showing the relationship between the second guide portion 80F and the second guided portion 43F shown in FIG. FIG. 11 shows a state in which the handle case 42 is slid to the vicinity of the position of the handle opening 21 (see FIG. 8). The positioning stopper 83 (the front rib 83) hits the handle case 42 when the handle case 42 is slid to the handle opening 21, thereby positioning a position in the vehicle front-rear direction with respect to the handle opening 21, that is, a slide end. It is a part to decide.

  Thus, as shown in FIGS. 8 and 11, since the positioning stopper 83 is provided on the back surface 22 of the door lining 20, when the handle case 42 is slid in the vehicle front-rear direction to the handle opening 21. The sliding of the handle case 42 is regulated by the positioning stopper 83. Since positioning in the vehicle front-rear direction with respect to the opening 21 for the handle can be easily performed, workability is good.

  Furthermore, the position of the positioning stopper 83 is set to a position where the handle case 42 can be finely adjusted in the vehicle front-rear direction after the handle case 42 is slid to the vicinity of the position of the handle opening 21. That is, when the handle case 42 is slid to the vicinity of the position of the handle opening 21, there is a slight gap Gp between the positioning stopper 83 and the front end of the second guided portion 43F. The size δ (interval δ in the front-rear direction) of the gap Gp is set to a size that allows the handle case 42 to be finely adjusted in the vehicle front-rear direction. For this reason, the attachment position of the handle case 42 with respect to the handle opening 21 can be finely adjusted in the vehicle front-rear direction to be easily set to the optimum position.

  Since the positioning stopper 83 for determining the sliding end of the handle case 42 is provided in the second guide portion 80F, it is not necessary to provide a separate stopper. For this reason, while being able to reduce the number of parts of the door 10, the narrow space in the back side of the door lining 20 can be utilized effectively.

Next, the pair of case attachment portions 90, 90 shown in FIGS. 7 and 8 will be described in detail. 12 is a perspective view showing the case mounting portion shown in FIG. As shown in FIG. 8, the case attachment portion 90 includes a clip attachment seat 91, a clip 95, and a fitting hole 45.
As shown in FIGS. 8 and 12, the clip mounting seat 91 is a substantially horizontal flat plate-like member extending from the back surface 22 of the door lining 20 to the door panel 70 side. Furthermore, the clip mounting seat 91 has a pair of protrusions 92 and 92 at both ends in the vehicle front-rear direction. The protrusions 92 and 92 extend from the back surface 22 of the door lining 20 to the door panel 70 side.

The clip 95 is a member that is elastically attached to the clip attachment seat 91 from the extending end 93 side. The first elastic piece 96 that is elastically attached to the clip attachment seat 91 and is attached with one touch, and the first elasticity. There are two second elastic pieces 97, 97 arranged on both sides of the piece 96. The second elastic pieces 97, 97 are disposed below the extended end 93 and can be elastically deformed in the vertical direction.
As shown in FIG. 12, on the upper surface of the clip mounting seat 91, clip position regulating ribs 94 and 94 (stoppers) for regulating the insertion depth of the clip 95 with respect to the clip mounting seat 91 are formed. .

  The attached portion 44 of the handle case 42 has a fitting hole 45. The fitting hole 45 is provided at a position facing the clip mounting seat 91 and the clip 95.

  By the way, the pair of projecting portions 92, 92 is formed of a vertical plate projecting toward the door panel 70 from the extending end 93 of the clip mounting seat 91. The amount of protrusion from the extended end 93 to the tip of the protrusion 92 is Pr. For this reason, the pair of projecting portions 92, 92 can restrict the position of the clip 95 attached to the clip attachment seat 91 from being displaced in the longitudinal direction of the vehicle body. The clip 95 can be held at an optimal position with respect to the clip mounting seat 91. Therefore, when attaching the handle case 42 to the case attaching portion 90, it is not necessary to correct the position of the clip 95, so that workability is good. Moreover, the elastic engagement between the inner surface of the fitting hole 45 and the second elastic pieces 97, 97 of the clip 95 can be maintained in a good state.

The operation of the case attaching portion 90 is as follows. FIG. 13 is an operational view of the case mounting portion shown in FIG.
First, when the handle case 42 is attached to the handle opening 21, as shown in FIG. 13A, the handle case 42 is moved along the back surface 22 of the door lining 20 in the front-rear direction (the front and back direction in FIG. 13). ). In the middle of the slide, as shown in FIG. 13A, the position of the fitting hole 45 is inconsistent with the clip mounting seat 91.

  Further, the protruding portion 92 protrudes from the extending end 93 of the clip mounting seat 91 toward the door panel 70 (see FIG. 8). For this reason, when the handle case 42 is slid, the protrusion 92 restricts the attached portion 44 (that is, the handle case 42) from contacting the clip 95. Therefore, there is no concern that the attached portion 44 will rub against the clip 95. For this reason, when the handle case 42 is slid back and forth in the vehicle, the attached portion 44 is not caught by the clip 95, so that the work can be smoothly performed and there is no fear that the attached portion 44 is damaged during the work. .

  When the handle case 42 is slid to the position of the opening 21 for the handle as shown in FIG. 8 by further sliding the handle case 42 in the front-rear direction, as shown in FIG. The position of the fitting hole 45 coincides with the seat 91. In this state, the attached portion 44 is moved toward the back surface 22 side of the door lining 20. As a result, as shown in FIG. 13C, the fitting hole 45 is inserted into the clip mounting seat 91 and the clip 95, so that the inner surface of the fitting hole 45 and the second elastic piece 97 of the clip 95 are elastic. It is attached with.

Next, the handle case 42 is slid forward along the back surface 22 of the door lining 20 to the handle opening 21. At this time, the guided portions 43R and 43F are guided in the front-rear direction by the guide portions 80R and 80F.

Thereafter, when the handle case 42 is slid to the handle opening 21, the positioning stopper 83 performs positioning in the vehicle front-rear direction with respect to the handle opening 21.
Next, the attachment position of the handle case 42 with respect to the handle opening 21 is finely adjusted in the vehicle longitudinal direction. This state corresponds to the state shown in FIG.

  Next, as shown in FIG. 14B, the lower portion of the handle case 42 is swung toward the back surface 22 of the door lining 20 with the positions of the guide portions 80 </ b> R and 80 </ b> F as swing fulcrums. As a result, the fitting hole 45 in the lower part of the handle case 42 is attached to the clip mounting seat 91 and the clip 95 (see FIG. 13C) with elasticity. This state corresponds to the state shown in FIG. Thus, the mounting operation of the handle case 42 is completed.

  In this manner, the guided portions 43R and 43F of the handle case 42 are attached to the door lining 20 by fitting between the back surface 22 of the door lining 20 and the guide portions 80R and 80F. Further, the attached portions 44 and 44 of the handle case 42 are attached to the door lining 20 by a clip attachment seat 91 and a clip 95.
