(Operation and effect of the embodiment)
Next, the operation and effect of the above embodiment will be described.

  As shown in FIG. 1, a front wall portion 18B is provided at an end portion of the side door 10 that is to be attached to the vehicle body, and the front wall portion 18B includes a pair of door hinge attachment portions 36A and 36B. Therefore, a load for supporting the weight of the side door 10 on the vehicle body acts on the front wall portion 18B via the door hinge (door side hinge pieces 38, 40, etc.). Further, when the side door 10 is closed and locked, inertial forces f1 and f2 (see FIG. 4) due to the built-in material of the side door 10 act so as to reciprocate substantially in the door thickness direction. Here, since the front wall portion 18B includes a surface substantially including the door thickness direction as a wall surface, and both end portions in the door vertical direction form a pair of door hinge mounting portions 36A and 36B, the inertial forces f1 and f2 (see FIG. 4) tries to deform the vicinity of the door hinge mounting portions 36A, 36B of the front wall portion 18B (particularly, the vicinity of the fastening portions of the door-side hinge pieces 38, 40).

  However, in the present embodiment, as shown in FIG. 2, a pair of beads 50 and 52 are formed on the front wall portion 18 </ b> B adjacent to the top and bottom of the door hinge mounting portion 36 </ b> B. Since the portions 50A and 52A extending in the door thickness direction are provided, even when the side door 10 is closed and locked, the inertia force f1 and f2 (see FIG. 4) in the door thickness direction acts. Deformation in the vicinity of the door hinge mounting portion 36 </ b> B is suppressed by the beads 50 and 52.

  Further, the hinge side panel 18 is formed with an end wall portion 18A constituting the door outer peripheral portion side bent at a substantially right angle from an end portion of the front wall portion 18B on the outer side of the vehicle compartment in the substantially door thickness direction, Since the lower bead 52 extends to the end wall portion 18A and has an L shape, the surface rigidity of the front wall portion 18B and the end wall portion 18A is increased. Therefore, even when a load acts on the front wall portion 18B when the door is closed, the relative displacement between the front wall portion 18B and the end wall portion 18A is suppressed, and the front wall portion 18B and the end wall portion continuous therewith are suppressed. With 18A, it resists the load. Therefore, the reliability of the strength with respect to opening and closing of the side door 10 can be secured without adding a patch or the like in the vicinity of the door hinge mounting portion 36B.

  Thus, in the vicinity of the door hinge mounting portion 36B, the rigidity around the hinge rotation axis CL is improved by the beads 50 and 52. In addition, the vicinity of the door hinge mounting portion 36B is also required to have rigidity around the axis in the door thickness direction, but according to the present embodiment, the bead 52 can also improve the rigidity around the axis in the door thickness direction. .

  Supplementally, during the rotational movement of the side door 10 shown in FIG. 1, a load F directed from the center of gravity C of the side door 10 toward the lower side of the door acts due to its own weight. This load F acts as a moment M1 around the axis in the door thickness direction on the door hinge attachment portion 36B side (also, a moment M2 around the axis in the door thickness direction on the door hinge attachment portion 36A side). However, in this embodiment, since the bead 52 extends to the end wall portion 18A and has an L shape, even if the moment M1 acts on the front wall portion 18B, the end wall 18B and the end wall portion 18B end. The moment M1 can be resisted by the wall 18A. For this reason, the rigidity around the axis in the door thickness direction is also improved in the vicinity of the door hinge mounting portion 36B.

  By these, the rigidity in the vicinity of the door hinge attachment part 36B is improved, and the stress at the fastening part of the door side hinge piece 40 can be reduced. It should be noted that the stress at the fastening portion of the door-side hinge piece 40 in this embodiment is reduced compared to the stress at the fastening portion of the door-side hinge piece in the comparison structure in which the pair of beads 50 and 52 are not formed. Confirmed by CAE analysis.

  Further, with the configuration of the present embodiment, it is possible to reduce the plate thickness of the hinge side panel 18 and to reduce the weight of the side door 10 while ensuring a predetermined strength in the vicinity of the door hinge mounting portion 36B. Incidentally, since the hinge side panel 18 is a component that fastens and supports the door hinge (door side hinge pieces 38 and 40), the plate thickness is thicker than the door inner panel body 16 and the door outer panel 12, and the area is also large. Since it is comparatively large, it can be said that it is a member with a large mass reduction effect.

  On the other hand, as shown in FIG. 2, the end wall 18 </ b> A is coupled to a part of the impact beam bracket 34 </ b> C at a position adjacent to the upper bead 50 that is paired with the lower bead 52. The surface rigidity in the vicinity of the upper side of the door hinge mounting portion 36B can be increased while suppressing the set number of beads in the end wall portion 18A using the above components. In this manner, the number of beads set is suppressed, so that it becomes easier to press-mold the hinge side panel 18.

  Further, as shown in FIG. 3, the hinge reinforcement 28 is coupled to the surface opposite to the side where the door-side hinge piece 38 (door hinge) is arranged with respect to the upper door hinge mounting portion 36A. The reinforcement 28 can increase the rigidity of the door hinge mounting portion 36A. For this reason, surface rigidity is increased while suppressing the set number of beads using existing parts, and press forming is facilitated by suppressing the set number of beads.

  As described above, according to the vehicle door structure of the present embodiment, the rigidity around the hinge rotation axis CL in the vicinity of the door hinge mounting portions 36A and 36B shown in FIGS. 2 and 3 is secured while suppressing an increase in mass. can do.

  In addition, the pair of beads 50 and 52 shown in FIG. 2 are configured to include portions 50A and 52A extending linearly in a substantially door thickness direction, but the beads are slightly in the door thickness direction. The bead comprised including the bead part extended while curving (in a large diameter circular arc shape) may be sufficient. Also, the extended portion 52B of the bead 52 may be extended slightly curved (in a large-diameter arc shape) in the end wall portion 18A. The same applies to the beads of the other modified examples described above.

  In the above embodiment, the end wall portion 18A of the hinge side panel 18 is coupled to a part of the impact beam bracket 34C at a position adjacent to the upper bead 50. For example, this part is the impact beam bracket. The upper bead (50) may be configured not to be coupled to a part of 34C and extend to the end wall portion 18A so as to have an L shape in plan view.
