Abstract: A hydraulic operating device for a small vehicle including a bicycle comprises a base member, a mounting structure, an operating member, and a piston. The base member includes a cylinder bore having a cylinder axis. The mounting structure defines a mounting axis linearly extending along the handlebar in a mounting state where the base member is mounted on a handlebar with the mounting structure. The operating member is pivotally coupled to the base member about a first pivot axis between a rest position and an operated position. The cylinder axis is non-perpendicular to the mounting axis as viewed along the first pivot axis in the mounting state. The piston is movably provided in the cylinder bore. The piston is coupled to the operating member to be pulled in response to a pivotal movement of the operating member from the rest position to the operated position.

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 pivotally coupled to the base member about a pivot axis. The piston is movably disposed in the cylinder bore and operatively coupled to the operating member to move the piston within the cylinder bore. The handlebar fixing structure is coupled to the base member. 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 hydraulic reservoir tank at least partially overlaps the handlebar arrangement area as viewed in a pivot axis direction parallel to the pivot axis of the operating member.

Abstract: A hydraulic device comprises a base member, a piston, a seal ring, and an intermediate member. The base member includes a cylinder bore and an annular groove. The annular groove includes a first inner surface and a second inner surface. The piston is movable relative to the base member from a rest position toward an actuated position in a second direction opposite to a first direction. The piston is movable relative to the base member from the actuated position toward the rest position in the first direction. The seal ring includes a first axial surface facing in the first direction and a second axial surface facing in the second direction. The seal ring is provided in the annular groove so as to define a clearance between the first axial surface and the first inner surface. The intermediate member is provided in the clearance.

Abstract: An adapter body is configured to be attached to a vehicle body in each of a first orientation in which a caliper body is coupled to the vehicle body via the adapter body in a first position corresponding to a first disc brake rotor having a first outer diameter, and a second orientation in which the caliper body is coupled to the vehicle body via the adapter body in a second position corresponding to a second disc brake rotor having a second outer diameter different from the first outer diameter. The indicator is configured to indicate an correspondence between an orientation of the adapter body and at least one of the first disc brake rotor and the second disc brake rotor.

Abstract: A hydraulic operating system for a small vehicle including a bicycle is basically provided with a base member, a piston, a hydraulic fluid chamber, a diaphragm and a deformation adjustment structure. The base member includes a cylinder bore. The piston is movably disposed in the cylinder bore. The hydraulic fluid chamber is fluidly connected to the cylinder bore. The diaphragm is at least partially defining the hydraulic fluid chamber. The diaphragm is deformed by fluid pressure in response to movement of the piston in the cylinder bore. The deformation adjustment structure is configured to selectively change a deformation condition of the diaphragm between at least two different deformation conditions.
