Abstract:
A bicycle hydraulic operating device is basically provided with a base member, a piston, an operating member and a hydraulic reservoir. The base member includes a cylinder bore. The piston is movably disposed in the cylinder bore. The operating member is coupled to the piston to move the piston within the cylinder bore. The hydraulic reservoir includes a hydraulic reservoir tank and a reservoir lid. The hydraulic reservoir is provided on the base member and is fluidly connected to the cylinder bore by a fluid passage. At least part of one of the base member and the hydraulic reservoir includes a fluid inspection portion making visually perceptible therethrough at least a portion of a hydraulic fluid flow path that includes the hydraulic reservoir, the cylinder bore and the fluid passage.
