Abstract: An operating device for a human-powered vehicle comprises a base, a piston, an operating member, an intermediate member, and a mounting structure. The base includes a hole. The piston is movably provided in the hole. The operating member is pivotally coupled to the base about a first pivot axis. The intermediate member is pivotally coupled to the base about a second pivot axis to transmit a pivotal movement of the operating member to the piston. The mounting structure is configured to couple the base and a handlebar of the human-powered vehicle. The mounting structure defines a mounting axis extending along the handlebar in a mounting state where the mounting structure couples the base and the handlebar. The first pivot axis is closer to the mounting axis than the second pivot axis in a perpendicular direction perpendicular to the mounting axis as viewed along the first pivot axis.

Abstract: An operating device comprises a base member and an operating member. The base member includes a base body and a mounting part. The mounting part includes a mounting contact surface contactable with a tubular part of the human-powered vehicle in a mounting state where the mounting part couples the base body to the tubular part of the human-powered vehicle. The base member includes a first contact surface and a second contact surface. The first contact surface is contactable with the tubular part of the human-powered vehicle in the mounting state. The first contact surface is spaced apart from the mounting contact surface in an axial direction. The second contact surface is contactable with the tubular part of the human-powered vehicle in the mounting state. The second contact surface is spaced apart from the mounting contact surface and the first contact surface in the axial direction.

Abstract: A hydraulic operating device for a small vehicle including a bicycle is basically provided with a base member, an operating member, a piston, a handlebar fixing structure and a hydraulic reservoir tank. The base member includes a cylinder having a cylinder bore. The operating member is pivots about a pivot axis to move the piston within the cylinder bore. The handlebar fixing structure defines a handlebar arrangement area. The hydraulic reservoir tank has a hydraulic fluid chamber fluidly connected to the cylinder bore. The cylinder defines a hydraulic pressure chamber with a space between the piston and a fluid outlet port of the cylinder. The hydraulic reservoir tank is partially disposed on a first side of the handlebar fixing structure while the hydraulic pressure chamber is disposed on a second side of the handlebar fixing structure as view in the pivot axis direction.
