  In particular, as described above, the connecting member 40 and the first inclined node member 50 are arranged so that the inclination angles thereof are substantially the same in a side view of the vehicle, that is, substantially parallel to each other. By arranging them continuously without being connected to each other, the connecting member 40 and the first inclined node member 50 can be configured to be arranged substantially linearly in a side view of the vehicle (see FIG. 6).

  Thus, the strength of the connecting portion 70A between the apron rain 30 and the connecting member 40 is increased by arranging the connecting member 40 and the first inclined node member 50 in a substantially straight line shape when viewed from the side of the vehicle. In addition, the force can be easily transmitted from the apron rain 30 to the connecting member 40, and vibration can be suppressed.

  More specifically, in order to efficiently transmit the force transmitted from the suspension tower 6 to the apron rain 30 to the connection member 40, the connection member 40 is connected to the interior of the front hinge pillar 20 at the connection portion 70 </ b> A between the apron rain 30 and the connection member 40. Although it can be considered that the structure penetrates the space 20Z, it is not preferable in securing the strength of the connecting portion 70A between the apron rain 30 and the connecting member 40.

  On the other hand, as in this embodiment, the first inclined node member 50 is connected to the connecting portion 70A of the connecting member 40 in the inner space 30Z of the apron rain 30 in a substantially straight line with the connecting member 40 in a side view of the vehicle. By providing such a configuration (see FIGS. 6 and 7), the connecting member 40 can be provided as if it penetrates the internal space 30Z of the apron rain 30.

  Therefore, after securing the strength of the connecting portion 70A between the apron rain 30 and the connecting member 40 by arranging the connecting member 40 and the first inclined node member 50 so as to be substantially straight when viewed from the side of the vehicle. The force can be easily transmitted from the apron rain 30 to the connecting member 40, and vibration can be further suppressed.

  Further, since the X-shaped reinforcing beads 58 and 68 are formed on the respective inclined partition surface portions 51 and 61 of the first inclined node member 50 and the second inclined node member 60 (see FIGS. 8 and 9), a plate shape The inclined partition surface portions 51 and 61 themselves can be increased in strength, and when the load is transmitted along with the vibration of the suspension tower 6, the tilt is also applied to the load acting on the rear surfaces of the inclined partition surface portions 51 and 61. The surfaces of the partition surface portions 51 and 61 are not crushed, and the strength can be ensured.

  The reinforcing beads 58 and 68 are not limited to being formed on the respective inclined partition surface portions 51 and 61 of the first inclined node member 50 and the second inclined node member 60, and may be formed on at least one of them. Moreover, it is not limited to the X shape, and may be formed in other shapes.

  Further, since the connecting portion 70A of the connecting member 40 of the apron rain 30 and the suspension tower 6 are arranged so as to overlap in the front-rear direction in a side view of the vehicle (see FIG. 5), the force accompanying the vibration of the suspension tower 6 Can be transmitted not only from the apron rain 30 to the connecting member 40 but also directly from the suspension tower 6, and vibration of the suspension tower 6 can be efficiently suppressed.
