FIG. 1
illustrates a conventional wheeled walker
5
. When the user pulls the brake levers
511
at the grips
51
of the handlebars
52
, the brake cables
6
are driven to stop the wheels
54
. The handlebars

SUMMARY OF THE INVENTION
The present invention has been accomplished to provide a wheeled walker brake lever mounting structure, which eliminates the aforesaid drawbacks. According to one aspect of the present invention, the wheeled walker brake lever mounting structure comprises a mounting base frame fixedly fastened to one handlebar of a wheeled walker, a brake cable inserted through the mounting base frame and connected to a brake assembly at the rear wheels of the wheeled walker, and a brake lever coupled to the mounting base frame and connected to the brake cable for turning by hand in either of two reversed directions to pull the brake cable and to further stop the wheeled walker. According to another aspect of the present invention, an auxiliary control block coupled to one side of the mounting base frame for turning with the hand to move the brake lever upwards or downwards and to achieve a braking action.
