1. A hydraulic operating device for a human-powered vehicle, the hydraulic operating device comprising:
a base including a cylinder bore defining a cylinder axis;
a hydraulic reservoir connected to the cylinder bore;
an operating member pivotally coupled to the base about a pivot axis between a rest position and an operated position; and
a handlebar mounting structure coupled to the base, the handlebar mounting structure defining a handlebar mounting axis that extends linearly along a handlebar in a mounted state in which the base is mounted to the handlebar by the handlebar mounting structure; and
a first torque transmission member movably mounted to the base, and a second torque transmission member movably mounted to the base, wherein
the cylinder axis of the cylinder bore is inclined towards the handlebar mounting axis as the cylinder bore extends away from the pivot axis as viewed in a pivot axis direction parallel to the pivot axis,
the first torque transmission member is pivotally coupled to the base about the pivot axis, and the second torque transmission member is pivotally coupled to the base about an additional pivot axis different from the pivot axis, and
the additional pivot axis is located in an area between the cylinder axis and the handlebar mounting axis as viewed in the pivot axis direction.
