  Next, the operation and effect of one embodiment of the present invention will be described.

  First, in order to clarify the operation and effect of the embodiment of the present invention, a comparative example will be described.

  As shown in FIG. 7, the instrument panel module structure 110 according to the comparative example includes an instrument panel reinforcement 112 and an extension 114. The instrument panel reinforcement 112 is configured by a pipe having a circular cross section, and the extension 114 is formed in a panel shape with the vehicle width direction as a plate thickness direction.

  The extension 114 has a fastening panel portion 120 in which a plurality of fastening holes 116 for fastening to the vehicle body and a holding hole 118 for holding by an external holding device (not shown) are formed.

  The fastening panel portion 120 has a mounting hole 122 formed therein. The end portion 112A of the instrument panel reinforcement 112 on the outer side in the vehicle width direction is inserted into the mounting hole 122, and the peripheral portion of the mounting hole 122 and the end portion 112A are welded in this state, whereby the extension 114 is It is joined to the portion 112A.

  In other words, in the instrument panel module structure 110 according to the comparative example, the holding hole 118 of the fastening panel portion 120 and the holding hole 134 of the extension panel portion 132 formed on the vehicle upper side of the fastening panel portion 120 are used. The portion 112A (extension 114) is held by an external holding device (not shown).

  However, in the instrument panel module structure 110 according to this comparative example, the extension panel portion 132 that is not related to the performance of the vehicle (fastening to the vehicle body) is the vehicle of the fastening panel portion 120 in order to secure the formation portion of the holding hole 134. It is formed to extend upward. Therefore, the extension 114 becomes unnecessarily large, and the cost and mass increase.

  On the other hand, as shown in FIG. 5, according to the instrument panel module structure 10 according to one embodiment of the present invention, the extension 14 is disposed outside the end portion 12 </ b> A of the instrument panel reinforcement 12 in the vehicle width direction. A main body panel portion 50 is formed with the vehicle width direction as the plate thickness direction. The holding hole 84 is formed in the main body panel portion 50 so as to be within the cross section of the end portion 12A of the instrument panel reinforcement 12 when viewed from the outside in the vehicle width direction.

Therefore, for example, if the holding pin inserted into the holding hole 84 has a cross-sectional shape similar to that of the holding hole 84, the instrument panel reinforcement 12 is rotated when assembling the outfitting component to the instrument panel reinforcement 12. Can be suppressed. Thereby, the assembly | attachment operation | work of the outfitting component to the instrument panel reinforcement 12 can be made favorable.

  Further, the entire instrument panel reinforcement 12 including the end 12A is formed in a quadrangular cross section. Therefore, for example, compared to the case where the instrument panel reinforcement 12 is formed in a circular cross section inscribed in the above-described square cross section (see the imaginary line L in FIG. 5), the end portion 12A of the instrument panel reinforcement 12 is cut off. Since the area increases, the holding hole 84 can be enlarged and formed. Accordingly, if the holding pin is formed to be enlarged in accordance with the holding hole 84, the holding rigidity by the external holding device described above can be ensured.

  As shown in FIGS. 2 and 3, the joining piece 56 and the joining portion 46 are welded by welding portions 72 and 74 aligned in the vehicle front-rear direction in a state where they are overlapped with each other in the vehicle up-down direction. . Therefore, even when the vehicle collides with the front, a load is applied to the welded portions 72 and 74 in the shearing direction at this time, so that peeling between the joining piece 56 and the joining portion 46 can be suppressed.

  Similarly, as shown in FIGS. 2 and 4, the joining piece 68 and the joining portion 48 are welded by welding portions 76 and 78 aligned in the vehicle vertical direction in a state where they are overlapped with each other in the vehicle longitudinal direction. Yes. Therefore, even when the vehicle collides with the front, a load is applied to the welded portions 76 and 78 in the shearing direction, so that peeling between the joining piece 68 and the joining portion 48 can be suppressed.

Next, a reference example of one embodiment of the present invention will be described.

  In one embodiment of the present invention, the holding hole 84 is formed in the shape of a long hole extending in the vehicle vertical direction. However, if the direction is orthogonal to the vehicle width direction, for example, in other directions such as the vehicle front-rear direction. It may be formed in a long hole shape.

  Further, although one holding hole 84 is formed in the extension 14, a plurality of holding holes 86 may be formed as shown in FIG. The plurality of holding holes 86 are formed side by side in the vehicle vertical direction.

  Even if configured in this way, for example, if the holding pins of the external holding device are respectively inserted into the plurality of holding holes 86, the instrument panel reinforcement 12 rotates when assembling the outfitting component to the instrument panel reinforcement 12. This can be suppressed. Thereby, the assembly | attachment operation | work of the outfitting component to the instrument panel reinforcement 12 can be made favorable.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and other various modifications can be made without departing from the spirit of the present invention. It is.
