A visor mounting structure includes a visor rod having a locking member secured to the rod to provide a predetermined rotational torque between the rod and the locking member. The locking member includes tabs extending outwardly for engaging one side of the sheet metal roof of a vehicle when installed. The assembly also includes a cover plate extending over the visor rod and axially spaced from the locking member and including tabs engaging an opposite side of the roof. When the locking member is inserted in the sheet metal roof and rotated to an engaging position, the cover plate is secured thereto to compressibly clamp the assembly in position in the vehicle, thereby mounting the visor attached to the visor rod to the vehicle.
