Mirror base

Abstract

A mirror base according to the present invention secures sufficient flexural strength of a support piece relative to a mount piece thanks to a reinforcing core member buried across the mount piece and the support piece, whereby the mount piece and support piece do not have to be integrally molded of a high-rigidity resin or die casting material, but can be integrally molded of a lightweight, inexpensive resin material. Since the core member is provided with mounting nut portions bordering a mounting surface of the mount piece and integrally molded with the core member, there is no need for a post-process of fixing mounting nut bushes or stud bolts to mounting bosses, for example, by heating and press fitting as needed before.

What is claimed is:  
     
         1 . A mirror base comprising a mount piece for mounting on a car; and a support piece projecting from the mount piece and adapted to support a mirror body, the mount piece and the support piece being integrally molded. of a resin, wherein a reinforcing core member is buried inside across the mount piece and the support piece.  
     
     
         2 . The mirror base according to  claim 1 , wherein the core member is provided with a rib for enhancing flexural rigidity of the support piece relative to the mount piece.  
     
     
         3 . The mirror base according to  claim 1 , wherein the core member is provided with a mounting portion bordering a mounting surface of the mount piece to be mounted on the car.  
     
     
         4 . The mirror base according to  claim 2 , wherein the core member is provided with a mounting portion bordering a mounting surface of the mount piece to be mounted on the car.  
     
     
         5 . The mirror base according to  claim 3 , wherein said mounting portion is a mounting nut portion.  
     
     
         6 . The mirror base according to  claim 3 , wherein said mounting portion is a mounting bolt portion.  
     
     
         7 . The mirror base according to  claim 4 , wherein said mounting portion is a mounting nut portion.  
     
     
         8 . The mirror base according to  claim 4 , wherein said mounting portion is a mounting bolt portion.  
     
     
         9 . The mirror base according to  claim 1 , wherein the core member comprises a continuous flange formed in a marginal region thereof.  
     
     
         10 . The mirror base according to  claim 2 , wherein the core member comprises a continuous flange formed in a marginal region thereof.  
     
     
         11 . The mirror base according to  claim 3 , wherein the core member comprises a continuous flange formed in a marginal region thereof.  
     
     
         12 . The mirror base according to  claim 4 , wherein the core member comprises a continuous flange formed in a marginal region thereof.  
     
     
         13 . The mirror base according to  claim 9 , wherein said core member is comprised of a pressed product.  
     
     
         14 . The mirror base according to  claim 10 , wherein said core member is comprised of a pressed product.  
     
     
         15 . The mirror base according to  claim 11 , wherein said core member is comprised of a pressed product.  
     
     
         16 . The mirror base according to  claim 12 , wherein said core member is comprised of a pressed product.
