US 2020/0086944 A1 · HYDRAULIC OPERATING DEVICE

Abstract

A hydraulic operating device comprises a base member, an operating member, a piston, and a mounting member. The base member includes a cylinder bore, a first hose-attachment hole, and a second hose-attachment hole. The first hose-attachment hole is configured to be in fluid communication with the cylinder bore. The second hose-attachment hole is configured to be in fluid communication with the cylinder bore. The operating member is pivotally coupled to the base member about a pivot axis. The mounting member is configured to couple the base member to a handlebar. The mounting member includes a mount opening through which the handlebar is to extend. The first hose-attachment hole, the second hose-attachment hole, and the mount opening are provided on a reference plane perpendicular to the pivot axis.
