As shown in FIGS. 3 and 5, the first step portion 33 of the pad member 30 is arranged above the character line 21 of the trim member 20 in a side view. In the present embodiment, the first step portion 33 is adjacent to the upper side of the vehicle with respect to the protruding portion 22a of the rib-shaped portion 22 formed on the vehicle outer surface of the trim member 20.

The first side surface portion 31 of the pad member 30 is arranged at a distance from the portion below the vehicle from the character line 21 of the trim member 20. The second side surface portion 32 of the pad member 30 is in contact with the rib-shaped portion 22 of the trim member 20. A fixing portion 36 for fixing the pad member 30 to the trim member 20 is formed in the second side surface portion 32 by inserting the protrusion 22b of the trim member 20. In addition to the second side surface portion 32, the fixing portion 36 between the trim member 20 and the pad member 30 includes a vehicle front side portion on the upper surface of the pad member 30 located on the upper side of the vehicle and a vehicle upper side portion on the side surface located on the rear side of the vehicle. Is also formed (see FIG. 4).

The second step portion 35 of the pad member 30 is adjacent to the upper side of the vehicle with respect to the upper end of the rib-shaped portion 22 of the trim member 20 in a side view. In the present embodiment, since the protrusion 22b is provided at the upper end of the rib-shaped portion 22, the second step portion 35 of the pad member 30 is arranged on the upper side of the vehicle with respect to the protrusion 22b. The third side surface portion 34 of the pad member 30 is in contact with the vehicle outer surface of the trim member 20. Further, the lower portion of the side surface of the pad member 30 located on the outer side of the vehicle is in contact with the bead-shaped portion 11a of the inner panel 11 (see FIG. 5).

Next, the operation of the vehicle side door structure according to the present embodiment will be described in detail.
In the side door 10 to which the structure as described above is applied, the outer panel 12 and the inner panel 11 are pushed inside the vehicle at the time of a side collision of the vehicle, so that the trim member 20 provided on the inner surface of the vehicle of the inner panel 11 is provided. Moves to the inside of the vehicle, and a portion of the trim member 20 below the character line 21 on the inner surface of the vehicle comes into contact with the grip portion 55 of the reclining lever 54.

At this time, the lower end portion of the pad member 30 provided in the space between the inner panel 11 and the trim member 20 extends below the grip portion 55 of the reclining lever 54 in a side view. The first side surface portion 31 of the side surface of the pad member 30 located inside the vehicle supports the trim member 20 in contact with the grip portion 55 of the reclining lever 54. As a result, it is possible to prevent the trim member 20 from being pushed to the outside of the vehicle, so that it is possible to suppress deformation of the trim member 20 to the outside of the vehicle.

Further, since the first step portion 33 of the pad member 30 is arranged on the upper side of the vehicle than the character line 21 of the trim member 20, the pad member 30 and the trim member 20 can easily mesh with each other, and the contact area between them can be increased. Can be expanded. As a result, slippage between the pad member 30 and the trim member 20 is suppressed, so that deformation of the trim member 20 to the outside of the vehicle can be effectively suppressed. If the deformation of the trim member 20 to the outside of the vehicle is suppressed, for example, the grip portion 55 of the reclining lever 54 falls into the character line 21 of the trim member 20 and is held, and the reclining lever is deformed by the deformation of the vehicle body such as the side door 10. It is possible to reduce the occurrence of a situation in which the rotation of the 54 is promoted.

Therefore, according to the vehicle side door structure of the present embodiment, the reclining lock state is released even if the grip portion 55 of the reclining lever 54 abuts and is pressed against the trim member 20 of the side door 10 at the time of a side collision. It is possible to prevent it from being stowed, and it is possible to fully obtain the effect of safety devices such as seat belts and airbags.

Further, in the vehicle side door structure of the present embodiment, the grid-like rib-shaped portion 22 is formed on the portion of the trim member 20 located above the character line 21 on the vehicle outer surface, so that a grid-like rib-shaped portion 22 is formed at the time of a side collision. , Deformation of the portion of the trim member 20 above the character line 21 can be suppressed, and the portion is less likely to be dented to the outside of the vehicle. Further, in addition to the rib-shaped portion 22 not being formed in the portion of the trim member 20 located below the character line 21 on the vehicle outer surface, the rib-shaped portion 22 is located at the position of the character line 21. Since the protruding portion 22a is formed so as to project outward, the trim member 20 is more likely to be deformed to the outside of the vehicle as the portion on the lower side of the vehicle is relatively easily deformed from the character line 21 as a starting point. As a result, it becomes difficult to form an inclined surface toward the upper side of the vehicle toward the outer side of the vehicle on the inner side surface of the trim member 20, so that the grip portion 55 of the reclining lever 54 in contact with the inner side surface of the vehicle of the trim member 20 is held above the vehicle. It is possible to suppress the generation of force to move to. Further, since the first step portion 33 of the pad member 30 is adjacent to the upper side of the protruding portion 22a of the rib-shaped portion 22 on the vehicle side, the displacement (slip) between the pad member 30 and the trim member 20 is surely suppressed. Therefore, it is possible to effectively support the trim member 20 by the pad member 30.

Further, in the vehicle side door structure of the present embodiment, the door beam member 13 is installed between the inner panel 11 and the outer panel 12, and the inner panel 11 is positioned so as to overlap the door beam member 13 in a side view. The bead shape portion 11a is formed. In the side door 10 reinforced by such a door beam member 13, the outer panel 12 and the door beam member 13 move inside the vehicle at the time of a side collision, for example, as shown in FIG. 7, and the door beam member 13 has a bead shape of the inner panel 11. The bead-shaped portion 11a is pressed against the inside of the vehicle in contact with the portion 11a. The bead-shaped portion 11a pressed by the door beam member 13 presses the lower portion of the side surface of the pad member 30 located on the outer side of the vehicle toward the upper inside of the vehicle. In the pad member 30 that receives the pressing force from the inner panel 11, the first side surface portion 31 of the side surface located inside the vehicle moves to the inside of the vehicle, and the first side surface portion 31 is formed on the outer surface of the vehicle of the trim member 20. The rib-shaped portion 22 abuts on the protruding portion 22a and presses the protruding portion 22a inward of the vehicle. At this time, as the side door 10 is pushed inside the vehicle, the trim member 20 also moves inside the vehicle, and the portion of the trim member 20 below the character line 21 on the inner surface of the vehicle is the grip portion of the reclining lever 54. It comes into contact with 55. In the trim member 20, since the protruding portion 22a of the rib-shaped portion 22 is pressed inside the vehicle by the pad member 30, deformation of the portion of the trim member 20 near the character line 21 to the outside of the vehicle is more effectively suppressed. be able to. The solid line in FIG. 7 shows the behavior when the vehicle side door structure of the present embodiment is applied, and the two-dot chain line shows the behavior when the vehicle side door structure of the present embodiment is not applied. Shows.

In addition, in the vehicle side door structure of the present embodiment, the second side surface portion 32 of the pad member 30 is in contact with the vehicle outer surface (rib-shaped portion 22) of the trim member 20, and the first pad member 30 is in contact with the first. The side surface portion 31 is arranged at a distance from the portion below the vehicle from the character line 21 of the trim member 20. As a result, the portion of the trim member 20 above the vehicle from the character line 21 is less likely to be deformed to the outside of the vehicle, while the portion below the character line 21 from the character line 21 is between the pad member 30 and the first side surface portion 31. Depending on the space, it is likely to be deformed to the outside of the vehicle, and the shape tends to be inclined toward the outside of the vehicle toward the lower side of the vehicle. Such an inclined shape of the portion below the character line 21 can effectively prevent the grip portion 55 of the reclining lever 54 in contact with the trim member 20 from being guided to the character line 21 side. ..

Further, in the vehicle side door structure of the present embodiment, the second step portion 35 of the pad member 30 is adjacent to the upper side of the vehicle from the upper end of the rib-shaped portion 22 of the trim member 20, and the second side surface of the pad member 30. A fixing portion 36 with the trim member 20 is formed in the portion 32. As a result, by aligning the second step portion 35 of the pad member 30 with the upper end of the rib-shaped portion 22 of the trim member 20, the protrusion 22b of the trim member 20 and the fixing portion 36 of the second step portion 35 of the pad member 30 are formed. Since the alignment of the pad member 30 is facilitated, the assembling property of the pad member 30 to the trim member 20 can be improved. Further, the fixing to the trim member 20 is performed only on the upper portion of the pad member 30, and the lower portion of the pad member 30 is in a free state, so that the pad member 30 and the trim are trimmed by the load at the time of a side collision. It is possible to reduce the possibility that a gap is generated between the member 20 and the member 20. This makes it possible to more reliably suppress the deformation of the trim member 20 in the vicinity of the character line 21.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications and modifications can be made based on the technical idea of the present invention. For example, in the above-described embodiment, the rib-shaped portion 22 is formed on the outer surface of the vehicle of the trim member 20, but the rib-shaped portion 22 can be omitted. In this case, the second side surface portion 32 of the pad member 30 may be brought into contact with the vehicle outer surface of the trim member 20.

Further, in the above-described embodiment, as for the side surface of the pad member 30 located inside the vehicle, an example is shown in which the third side surface portion 34 and the second step portion 35 are provided on the upper side of the vehicle of the second side surface portion 32. The configuration in which the three side surface portions 34 and the second step portion 35 are not formed, that is, the side surface of the pad member 30 located inside the vehicle is composed of the first side surface portion 31, the second side surface portion 32, and the first step portion 33.
