<Configuration> The configuration of this embodiment will be described below.
A vehicle such as an automobile is provided with an instrument panel 1 as shown in FIG. A glove box 2 is provided on the passenger panel side of the instrument panel 1.

  The glove box 2 is provided with a lid 4 that can be opened and closed on the surface side of a box-shaped glove box body (not shown). Then, as shown in the longitudinal sectional view of FIG. 2, the lid 4 is formed by integrating the outer lid 5 and the inner lid 6 by vibration welding with a gap 7 between the opposing surfaces. The

  Here, the glove box main body includes a box type in which the lid 4 is attached so as to be openable and closable and a bucket type in which the lid 4 is integrally provided. The outer lid 5 and the inner lid 6 are preferably substantially parallel to each other, but the outer lid 5 has a three-dimensional curved surface shape according to the surface on the near side of the instrument panel 1 and may not be parallel. possible. In the figure, the non-parallel state is exaggerated.

And the outer side welding rib 13 extended in the vibration direction 11 by vibration welding on the surface facing the inner lid 6 of the said outer lid 5 and projecting smaller than the said gap | interval part 7 is provided.
On the other hand, an inner side welding rib 14 that extends in the vibration direction 11 on the surface of the inner lid 6 facing the outer lid 5 and is butted in line contact with the outer side welding rib 13 and is vibration welded. Is provided.

  Here, the vibration direction 11 of vibration welding is, for example, substantially the vehicle width direction (or the vertical direction). The protruding amount of the outer side welding rib 13 is, for example, about half the height of the gap 7. A plurality of outer side welding ribs 13 are provided so as to be as dense as possible. A plurality of inner side welding ribs 14 are formed at the same position (opposite position) as the outer side welding ribs 13 so as to have a difference height between the gap 7 and the protruding amount of the outer side welding ribs 13. The alignment line of the outer side welding rib 13 and the inner side welding rib 14 preferably extends linearly in the vibration direction 11, but has an intermediate angle between the outer lid 5 and the inner lid 6. It only needs to extend linearly.

Further, the outer lid 5 extends in a direction crossing the vibration direction 11 on the surface facing the inner lid 6, has a larger protrusion than the outer side welding rib 13, and the inner side welding rib 14 Outer side guide ribs 22 for guiding movement in the vibration direction 11 are provided.
On the other hand, the inner lid 6 extends in a direction crossing the vibration direction 11 at a position different from the outer side guide rib 22 on the surface of the inner lid 6 facing the outer lid 5, and is larger than the inner side welding rib 14. An inner side guide rib 24 is provided to guide the movement of the outer side weld rib 13 in the vibration direction 11 in a certain amount.

  Here, as shown in FIG. 3, the direction intersecting with the vibration direction 11 is, for example, a direction orthogonal to the vibration direction 11. However, the outer side guide rib 22 and the inner side guide rib 24 are not limited to this as long as they do not interfere with each other.

  The “outer side guide rib 22” is integrated with the outer side weld rib 13 for a portion up to the same height as the outer side weld rib 13, and is independent for a portion exceeding the height of the outer side weld rib 13. It is extended with. And the slit part 25 which can clamp the inner side welding rib 14 is formed in the part exceeding the height of the outer side welding rib 13 of the outer side guide rib 22, and on the entrance side of this slit part 25, When the outer lid 5 and the inner lid 6 are combined, the guide taper portion 26 for calling the inner side welding rib 14 is formed. A plurality of outer side guide ribs 22 are provided with a required interval.

  Similarly, the “inner side guide rib 24” is integrated with the inner side weld rib 14 in a portion up to the same height as the inner side weld rib 14, and a portion exceeding the height of the inner side weld rib 14. Is extended alone. A slit portion 27 capable of sandwiching the outer-side welding rib 13 is formed at a portion exceeding the height of the inner-side welding rib 14, and the outer lid 5 and the inner lid are formed on the entrance side of the slit portion 27. When combining with the lid 6, a guide taper portion 28 for calling the outer side welding rib 13 is formed. A plurality of inner side guide ribs 24 are provided with a required interval.

  Furthermore, the outer side guide ribs 22 and the inner side guide ribs 24 are arranged alternately. Furthermore, it is preferable that the outer side guide ribs 22 and the inner side guide ribs 24 are formed at an intermediate portion of each other so as to have substantially the same pitch. The outer side guide rib 22 and the inner side guide rib 24 are formed to be as dense as possible as a whole.

  Further, as shown in FIG. 2, between the tip of the outer guide rib 22 and the facing surface of the inner lid 6, and between the tip of the inner guide rib 24 and the facing surface of the outer lid 5. Furthermore, when the emergency input load 31 is applied to the lid body 4 from the outside, the load absorbing gaps 32 and 33 that can absorb the emergency input load 31 are set.

  Here, the load absorbing gaps 32 and 33 are configured such that, for example, the base portion (root portion) of the outer side welding rib 13 and the inner side welding rib 14 is deformed by the emergency input load 31. The load absorbing gaps 32 and 33 are set by the difference between the protruding amount of the outer guide rib 22 and the protruding amount of the inner guide rib 24 and the gap 7. These protruding amounts 23 are generally about 70 to 95% of the gap 7. Note that at least one or both of the load absorbing gaps 32 and 33 are provided.

<Effect> According to this embodiment, the following effects can be obtained.
The glove box 2 can store articles inside the glove box body by opening and closing the lid 4.

  And the above-mentioned cover body 4 shall be what integrated the outer lid 5 and the inner lid 6 by vibration welding. A required gap 7 is provided between the outer lid 5 and the inner lid 6.

  The outer lid 5 and the inner lid 6 are joined together by vibration welding while the outer side welding rib 13 and the inner side welding rib 14 extending in the vibration direction 11 are abutted in a line contact state.

  At the time of vibration welding, the outer side guide rib 22 guides the movement of the inner side weld rib 14 in the vibration direction 11, and the inner side guide rib 24 provided at a position different from the outer side guide rib 22 The movement of the welding rib 13 in the vibration direction 11 is guided.

  Thus, the inner side welding ribs 14 and the outer side welding ribs 13 are guided by using the outer side guide ribs 22 and the inner side guide ribs 24, respectively. Even when the welding rib 13 is long, both can be maintained in a good state and can be vibrated and welded efficiently.

  Further, for example, the outer side welding ribs 13 and the inner side welding ribs 14 joined by vibration welding are used as horizontal ribs, and the outer side guide ribs 22 and the inner side guide ribs 24 are formed at different positions (alternately). When the vertical ribs are used, the lateral ribs and the vertical ribs can be densely formed in the gap portion 7 in a state where the outer lid 5 and the inner lid 6 are joined. Therefore, the surface rigidity of the lid 4 is increased by increasing the number of horizontal ribs and vertical ribs without being subjected to restrictions on injection molding (for example, installation positions of cooling pipes and eject pins and various conditions such as molding cycles). Will be able to.

  And between the front end of the outer side guide rib 22 and the opposing surface of the inner lid 6, and between the front end of the inner side guide rib 24 and the opposing surface of the outer lid 5, respectively, a load absorbing gap 32, 33 was set. Thereby, when the emergency input load 31 acts on the cover body 4 from the outside, the emergency input load 31 can be absorbed, for example, by deforming the bases of the outer side welding rib 13 and the inner side welding rib 14. . As a result, it is possible to increase the load absorption force with respect to the direction perpendicular to the surface of the lid 4.
