  The base portion 70 has a predetermined length, and when the inner weather strip 10 is assembled to the inner weather strip mounting portion 36, as shown in FIG. 9, the front end 80 becomes the front end 49a of the first fitting portion 48a (FIG. 4). The rear end 82 is positioned slightly rearward from the rear end 57d (see FIG. 4) of the fourth fitting portion 48d.

  Each of the upper lip 72 and the lower lip 74 has a substantially elliptical cross section, and is provided on a surface 71 on the vehicle exterior side of the base portion 70 with a predetermined interval in the vertical direction. As shown in FIG. 8, when the door trim 20 is attached to the rear side door 16, the upper lip 72 and the lower lip 74 are always in sliding contact with the window glass 24 in a state of facing obliquely upward on the vehicle exterior side. When the upper lip 72 and the lower lip 74 are in a free state, the upper lip 72 and the lower lip 74 are basically arranged in a state slightly upward from the vertical with respect to the base 70.

  As shown in FIG. 6, both ends of the inner weather strip 10 in the longitudinal direction (front-rear direction) are formed obliquely such that the upper end edge 90 of the base portion 70 protrudes outward from the lower end edge 92. That is, the inner weather strip 10 has an upper end 90 protruding forward from the lower end edge 92 at the front end 80 and an upper end edge 90 protruding rearward from the lower end edge 92 at the rear end 82.

  As shown in FIG. 7, the insertion portion 76 is provided on the room-side surface 73 of the base 70 substantially perpendicular to the room-side surface 73 of the base 70. The insertion portion 76 includes three protrusions 84 on the upper surface and two protrusions 86 on the lower surface. Each projecting piece 84 and projecting part 86 are provided continuously along the longitudinal direction of the base part 70.

Demonstrates resistance when pulled out from.

  The protrusion 78 is provided on the indoor-side surface 73 of the base 70. The ridge 78 is positioned below the insertion portion 76, protrudes from the base portion 70 at a predetermined height, and is provided continuously along the longitudinal direction of the base portion 70.

  The inner weather strip mounting structure referred to in the present embodiment and claims refers to the shape of the inner weather strip 10 and the structure of the inner weather strip mounting portion 36 together.

  Next, the operation and effect of the inner weather strip mounting structure according to the embodiment will be described. In assembling the inner weather strip 10, the operator inserts the insertion portion 76 of the inner weather strip 10 from the first fitting portion 48a provided on the door trim 20 shown in FIG. 3 into the fourth fitting portion 48d. Put in. The insertion portion 76 is fitted in a state in which the protruding piece 84 is deformed and is in close contact with the inner surface of the first fitting portion 48a and the like, and is not easily removed from the first fitting portion 48a and the like.

  Since the space between the third fixing portion 40 c and the fourth fixing portion 40 d is curved along the belt line as shown in FIG. 4, the operator curves the inner weather strip 10 to the guide piece 60. Install in a curved state. As a result, as shown in FIG. 9, the inner weather strip 10 is attached to the door trim 20 while drawing a smooth curve along the upper edge 25 of the door trim 20.

  As shown in FIG. 5, the fourth fitting portion 48 d is provided with a narrow width portion 56, and the projecting piece 84 is deformed more greatly inside the narrow width portion 56 so as to be in close contact with the inner surface, and the insertion portion 76 is strongly fitted to the fourth fitting portion 48d. Therefore, even if the inner weather strip 10 is fitted in a curved state so that the vicinity of the rear end 82 is inclined upward, it is held by the door trim 20 with a strong fitting force. Further, in the narrow width portion 56, the inner weather strip 10 is strongly held by the lower wall piece 54 whose upper surface 55 is raised, so that the inner weather strip 10 can be prevented from drooping.

  Next, the operator inserts the first regulating plate 50a of the door trim 20 between the door inner panel 32 and the door outer panel 30 as shown in FIG. Then, the restriction plates of the first restriction plate 50 a to the fourth restriction plate 50 d are engaged with the door inner panel 32, and the upper edge 25 of the door trim 20 is engaged with the door inner panel 32.

  Thereby, the inner weather strip 10 is disposed between the door inner panel 32 and the window glass 24, and further, the first restriction plate 50a to the fourth restriction plate 50d of the first fixing portion 40a to the fourth fixing portion 40d are arranged. The upper lip 72 and the lower lip 74 are pressed against the window glass 24 in contact with the base 70. The door trim 20 engaged with the door inner panel 32 is fixed to the door inner panel 32 with a clip or the like.

  Further, in the vicinity of the rear end of the inner weather strip 10, the base portion 70 is pressed to the outdoor side by a thick portion 62 provided on the fourth regulating plate 50d as shown in FIG. Since the base portion 70 is pressed by the thick portion 62, the upper lip 72 and the lower lip 74 located near the rear end of the inner weather strip 10 are more strongly pressed against the wind glass 24. Further, since the thick part 62 is provided at the lower part of the fourth restricting plate 50d, it acts to lift the base part 70 from below, thereby preventing the base part 70 from drooping, that is, preventing the upper lip 72 and the lower lip 74 from falling. Thus, the upper lip 72 can be neatly aligned with the curvature of the belt line.

  Further, since the inner weather strip 10 is pressed toward the window glass 24 from below by the thick portion 62, the inner weather strip 10 is urged in the rightward R direction in FIG. Also in this manner, a force in a direction of pushing the insertion portion 76 into the fourth fitting portion 48d acts in the vicinity of the rear end of the inner weather strip 10, and the insertion portion 76 at the place from the fourth fitting portion 48d is applied. Is suppressed from coming out.

  As described above, according to the inner weather strip mounting structure of the present embodiment using the inner weather strip 10 and the inner weather strip mounting portion 36, the following effects can be obtained.

  Even when the inner weather strip 10 is curved, it can be attached to the door trim 20 with good appearance. The inner weather strip 10 can be easily attached from the first fitting portion 48a to the third fitting portion 48c basically in the same manner as in the prior art, and is slightly stronger at the narrow width portion 56 of the fourth fitting portion 48d. By pressing, the inner weather strip 10 can be reliably fitted.

  Since the insertion portion 76 is strongly held by the narrow width portion 56, the inner weather strip 10 can stably hold the curved state. Further, since the insertion portion 76 is strongly held by the narrow width portion 56, the inner weather strip 10 is also used in the process of transporting or storing the door trim 20 with the inner weather strip 10 attached to the door trim 20. Does not come off from the door trim 20, and the door can be assembled easily.

  Since the narrow portion 56 has the height of the upper surface 55 of the lower wall piece 54 higher than the portion other than the narrow portion 56, when the insertion portion 76 is inserted into the narrow portion 56, the insertion portion 76 is supported so that it can be lifted from below. Accordingly, the inner weather strip 10 is bent with a curvature that is more strongly curved upward than the curvature of the fitting portion 48 when the narrow width portion 56 is not present, and the inner weather strip 10 is bent along the curvature of the belt line and is time-consuming. Even if the position of the inner weather strip 10 is slightly lowered as time passes, a desired curved state can be maintained for a long time.

  When the door trim 20 is attached to the door inner panel 32, the protrusion 78 of the base portion 70 of the inner weather strip 10 is pressed toward the wind glass 24 by the first restricting plate 50a and the door inner panel 32. In particular, since the base 70 is pressed by the fourth restriction plate 50d or the like via the protrusion 78, the shape of the inner weather strip 10 at the curved portion can be better maintained.

  The thick portion 62 presses the base 70 to the outdoor side in the vicinity of the rear end of the inner weather strip 10, so that the pressing force of the upper lip 72 and the like is increased and the vicinity of the rear end of the inner weather strip 10. This effectively prevents the insertion portion 76 from coming off.

  By providing the thick portion 62 at a place where the narrow portion 56 is not provided, it is possible to effectively prevent the insertion portion 76 fitted to the wide fourth fitting portion 48d other than the narrow portion 56 from being pulled out. . Further, by providing the thick portion 62, the length of the narrow portion 56, which requires a force when inserting the insertion portion 76, can be shortened.

  In addition, this invention is not limited to the said embodiment, You may use it changing suitably.
