Claims

[Scope of utility model registration request]

An annular peripheral wall portion that can be fitted to the outer periphery of the tip of the mounting boss of the vehicle mirror base integrally molded with synthetic resin, and when the peripheral wall portion is fitted to the outer periphery of the tip, the mounting screw is forcibly screwed. It is characterized by being formed by a top wall portion provided with a mounting screw insertion hole facing the opening of the boss hole of the mounting boss to be fitted, and consisting of a cap-shaped metal fitting fitted to the tip of the mounting boss. Reinforcing metal fittings for mounting bosses on synthetic resin mirror bases for vehicles.
