Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle interior panel mounting structure for mounting a synthetic resin interior panel to a support panel, and more particularly, to a vehicle interior panel mounting structure. A mounting plate portion inserted into the mounting hole is continuously provided on an interior panel made of synthetic resin in which at least a part of the outer peripheral portion is in contact with a front surface of a peripheral portion of the mounting hole, and the mounting plate portion is provided on the mounting plate portion. The present invention relates to a mounting structure for an interior panel for a vehicle in which an engaging claw is engaged with a support panel from a rear side. 2. Description of the Related Art Conventionally, as shown in FIG. 8, a mounting hole 42 of a support panel 11 such as an instrument panel is provided with an interior panel 13 'such as an outlet panel constituting a part of an air-conditioning blowout device. When installing the panel, the interior panel 1
The mounting plate 47 "integrally connected to 3 'is attached to the mounting hole 42.
An engaging claw 48 which is inserted into the mounting plate portion 47 '' and is engaged with the rear end of the locking portion 43 provided integrally with the support panel 11 so as to be continuous with the peripheral portion of the mounting hole 42 is provided on the mounting plate portion 47 ''. Attachment plate portion 47 "in which engagement claw 48 is elastically engaged with stop portion 43.
In order to maintain rigidity, a reinforcing rib 52 is provided integrally with the interior panel 13 '. However, there is a case where the space for providing the reinforcing rib 52 cannot be secured on the side of the interior panel 13 ', in which case the rigidity of the mounting plate 47 "is not sufficient. Even if the reinforcing ribs 52 can be provided, in order to prevent sink marks on the interior panel 13 'side at the continuous portion of the reinforcing ribs 52, the thickness of the reinforcing ribs 52 is required. In some cases, the thickness must be set relatively small, and the rigidity of the mounting plate portion 47 ″ cannot be secured by the reinforcing rib 52. The present invention has been made in view of the above circumstances, and has been made in consideration of the above circumstances, and has been made to prevent the occurrence of sink marks or the like on the interior panel side, and to sufficiently secure the rigidity of the mounting plate portion.
