Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an instrument panel structure for an automobile provided with a support piece that allows a resin instrument panel to support vehicle components.
[0002]
[Prior art]
An automobile is generally provided with a resin instrument panel that is disposed in the front of a passenger compartment and extends in the vehicle width direction. The instrument panel forms an upper portion in a side sectional view. An upper panel extending in the front-rear direction, and an extending panel extending integrally from the rear end portion of the upper panel toward the front lower side.
[0003]
The instrument panel is usually injection-molded. In this case, the mold can be contacted and separated in the direction along the extending direction of the extending panel so that the structure of the mold is simplified. A pair of mold members is provided.
[0004]
Further, conventionally, in addition to the instrument panel having the above-described configuration, there is one provided with a support piece that integrally protrudes downward from the lower surface side of the upper panel and enables the vehicle component to be supported at the protruding end. In this case, the support piece is protruded in the extending direction of the extending panel, that is, in the contact / separation direction of the mold members so that the instrument panel can be molded by the mold. ( Japanese Utility Model Publication No. 7-47228 ).
[0005]
[Problems to be solved by the invention]
By the way, at the time of molding the instrument panel, since the volume of the resin material is larger at the joint between the upper panel and the support piece than the other part of the upper panel, the resin material after mold release is cured. Due to the contraction, sink marks (outer lands) tend to occur on the upper surface of the upper panel corresponding to the coupling portion.
[0006]
Here, in particular, in the conventional technique, the support piece is bonded to the upper panel at a small angle of intersection, and accordingly, the area in plan view of these connecting portions is increased. This is also undesirable because it increases the surface area of the instrument panel and causes the appearance of the instrument panel to deteriorate.
[0007]
The present invention has been made paying attention to the above-described circumstances. When a resin instrument panel includes a support piece that can support vehicle components, the appearance of the instrument panel can be improved. It is an object to ensure that is maintained well.
[0008]
