The invention relates to a construction of vehicle rearview mirror which conforms with the Federal Safety Regulations concerning interior mirrors, namely, that the mirror mounting shall break away or deflect or collapse when struck by a force of 90 lbs. The mounting comprises a ball head on the mirror arm which fits within a complementary socket of a resilient plastics material, such as "Delrin", forming the base part of the mounting. The arm also carries a shoulder which abuts the top of the base part and forms therewith a fulcrum about which the arm rocks to force the ball head out of the socket when the mirror is struck.
