Abstract: An operating assembly for a small vehicle including a bicycle is basically provided with a base member, an operating member, a handlebar fixing structure and a handlebar spacer. The base member includes a support. The operating member is movably coupled to the base member. The handlebar fixing structure is coupled to base member. The handlebar fixing structure defines a handlebar receiving area. The support is spaced from the handlebar receiving area of the handlebar fixing structure in a parallel direction parallel to a handlebar axis defined by the handlebar receiving area. The handlebar spacer is disposed between a handlebar and one of the support and the handlebar fixing structure in a mounted state where the operating device is mounted to the handlebar.

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 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 apparatus for a small vehicle, including a bicycle, comprises a housing, a piston, a mounting assembly, a lever, and a fluid reservoir tank. The housing includes a cylinder bore extending along a cylinder axis. The piston is movably disposed within the cylinder bore. The mounting assembly is configured to mount the housing to a handlebar of the small vehicle. The mounting assembly defines a handlebar mounting axis that is not perpendicular to the cylinder axis in a mounted state where the housing is mounted to the handlebar. The lever is pivotally mounted to the housing and configured to move the piston within the cylinder bore in response to a movement of the lever. The fluid reservoir tank has a lid opening. The lid opening is configured to face a center plane that passes through a geometric center of the handlebar and that is perpendicular to the handlebar mounting axis, in the mounted state.

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.
