It will be. As a result, a reaction force is generated when the first fixing portion 7 is inserted into the gap S, and the door outer pad 6 is pushed up in the direction opposite to the insertion direction by the reaction force so that the clip 8 of the second fixing portion 9 is stiffened. 5 is bitten. The clip 8 is brought into close contact with the hole 14 of the stiffener 5 by the reaction force, so that the door outer pad 6 is attached to the stiffener 5 without rattling.

"Effect"
In the side door structure configured as described above, when the outer panel 1 is touched, a load input to the outer panel 1 is transmitted to the door outer pad via the panel deformation preventing projection 11 in contact with the outer panel 1. 6 is input. The door outer pad 6 supports the load input from the panel deformation preventing projection 11.

  Further, the second fixing portion 9 that fixes the door outer pad 6 to the stiffener 5 is loaded in the shearing direction of the clip 8 with respect to the input load from the outer panel 1. At this time, when the flange portion 8 a formed at the tip of the clip 8 is deformed, rattling of the clip 8 is suppressed at the second fixing portion 9. That is, in the second fixing portion 9, the clip 8 is attached from the lower side of the vehicle toward the upper side of the vehicle with respect to the inclined surface 12 of the bent portion in which a part of the stiffener 5 is recessed in a substantially L shape. Since the clip 8 is engaged with the hole portion 14 by the reaction force when the fixing portion 7 is inserted into the gap S, the attachment of the clip 8 is inclined even if the flange portion 8a is deformed. Biting is less than minutes.

  Further, according to the vehicle side door structure of the present embodiment, the panel deformation preventing projection 11 provided on the door outer pad 6 is in contact with the outer panel 1, so that a predetermined amount of clearance is provided to the outer panel 1. Compared with the conventional structure in which the door outer pad is disposed, it is possible to eliminate the feeling of insufficient rigidity of the outer panel 1.

  Further, according to the vehicle side door structure of the present embodiment, the inclined surface 12 of the bent portion in which the second fixing portion 9 is partially recessed from the outer panel side to the inner panel side of the stiffener 5 extending in the vehicle vertical direction Z. Therefore, the clip 8 can be attached to the inclined portion from the lower side of the vehicle toward the upper side of the vehicle.

  Further, according to the vehicle side door structure of the present embodiment, the flange portion 8 a is provided at the tip of the hole portion 14 formed in the bent portion of the stiffener 5 through the through hole 13 formed in the inclined portion of the second fixing portion 9. Since the clip 8 is inserted and the door outer pad 6 is fixed to the stiffener 5, rattling between the door outer pad 6 and the stiffener 5 can be reduced by the amount of the clip 8 being inclined.

  Further, according to the vehicle side door structure of the present embodiment, the concave portion having the same shape is formed in the door outer pad 6 in accordance with the substantially L-shaped bent portion formed in the stiffener 5. Since 5 bites into the door outer pad 6, the rattling of both is further reduced.

  The specific embodiment to which the present invention is applied has been described above, but the above-described embodiment is an example of the present invention and is not limited to the above-described embodiment.
