Nifco Inc. (Headquarters: Yokosuka City, Kanagawa Pref., President: Masaharu Shibao (hereinafter, Nifco)) has commercialized and started mass production of easy-to-recycle resin service hole covers for door mirrors.

In recent years, the automobiles that do not emit engine noise, such as EV whose market is expanding, have increasing demand for sound insulation against road noise, and, in order to secure the interior tranquility and comfort, there is an increasing need for parts with high sound insulation that close even the small work holes required when assembling the car body.
In addition, global needs for reducing environmental impact continue to be high, and there are expectations for the use of highly recyclable materials or structure for automotive plastic parts.  
In response to all of these needs, Nifco has developed a resin cover that closes the service hole for door mirrors (the work hole required when assembling the door mirror to the vehicle body), using easily recyclable materials and the structure.  
This product is installed in the Toyota Motor Corporation ‘Crown’ and contributes to the realization of a comfortable interior space.
