Claims

[Scope of utility model registration request]

A brake operating device in which a brake lever 4 is pivotally supported on a bracket 3 via a lever shaft 5, and an operating cable is operated by operating the brake lever 4 from a return position relative to the bracket 3 to an operating position to operate the brake. The bracket 3 supports a lever spring 6 that biases the brake lever 4 toward the return position.
The brake lever side spring foot 61 is inclined with respect to the axis of the lever shaft 5 so that its free end approaches the top inner surface 4a of the brake lever 4, and the top inner surface is attached to the inclined free end 61a. A bicycle brake operating device characterized in that a roller 7 in contact with a roller 4a is rotatably supported.
