摘要

A brake operating device mounted to a bicycle handle, in which a bracket having a first abutting member pivotally supports an operating lever having a second abutting surface for abutting the first abutting surface. Each abutting surface is formed in a circular arc centered at a position spaced from the pivot point of the lever relative to the bracket. The pivot point is shifted on the circumference of a circle which is concentric with the circular arcs forming the first and second abutting surfaces to adjust the grip dimension between the handle and the operating lever.
