Bicycle operating device
First Claim
1. A bicycle operating device comprising:
- a base member;
an operating member pivotally coupled to the base member about a pivot axis; and
a hydraulic unit provided on the base member and comprising;
a hydraulic cylinder including a cylinder bore being at least partly provided above the pivot axis in a mounting state where the bicycle operating device is mounted to a bicycle;
a piston movably provided in the cylinder bore, the cylinder bore and the piston defining a hydraulic chamber; and
a hydraulic reservoir including a reservoir chamber connected to the hydraulic chamber, the reservoir chamber being provided to at least partially overlap from above the cylinder bore without overlapping with the cylinder bore in a transverse direction parallel to the pivot axis in the mounting state.

Abstract
A bicycle operating device comprises a base member, an operating member, and a hydraulic unit. The operating member is pivotally coupled to the base member about a pivot axis. The hydraulic unit is provided on the base member and comprises a hydraulic cylinder, a piston, and a hydraulic reservoir. The hydraulic cylinder includes a cylinder bore being at least partly provided above the pivot axis in a mounting state where the bicycle operating device is mounted to a bicycle. The piston is movably provided in the cylinder bore. The cylinder bore and the piston define a hydraulic chamber. The hydraulic reservoir includes a reservoir chamber connected to the hydraulic chamber. The reservoir chamber is provided above the cylinder bore without overlapping with the cylinder bore in a transverse direction parallel to the pivot axis in the mounting state.

14. A bicycle operating device comprising:
-
a base member; an operating member pivotally coupled to the base member about a pivot axis; and a hydraulic unit provided on the base member and comprising; a hydraulic cylinder including a cylinder bore being at least partly provided above the pivot axis in a mounting state where the bicycle operating device is mounted to a bicycle; a piston movably provided in the cylinder bore, the cylinder bore and the piston defining a hydraulic chamber; and a hydraulic reservoir including a reservoir chamber connected to the hydraulic chamber, the reservoir chamber being provided above the cylinder bore without overlapping with the cylinder bore in a transverse direction parallel to the pivot axis in the mounting state, wherein the operating member is pivotable relative to the base member about the pivot axis between a rest position and an operated position, and the piston is configured to be pushed from an initial position to an actuated position in response to a movement of the operating member from the rest position toward the operated position to supply a hydraulic pressure toward at least one bicycle component.

15. A bicycle operating device comprising:
-
a base member; an operating member pivotally coupled to the base member about a pivot axis; and a hydraulic unit provided on the base member and comprising; a hydraulic cylinder including a cylinder bore being at least partly provided above the pivot axis in a mounting state where the bicycle operating device is mounted to a bicycle; a piston movably provided in the cylinder bore, the cylinder bore and the piston defining a hydraulic chamber; and a hydraulic reservoir including a reservoir chamber connected to the hydraulic chamber, the reservoir chamber being provided above the cylinder bore without overlapping with the cylinder bore in a transverse direction parallel to the pivot axis in the mounting state, wherein the piston is movable relative to the hydraulic cylinder in a movement direction, the cylinder bore has a cylinder center axis extending in the movement direction, and the cylinder bore is arranged without overlapping with the pivot axis as viewed in a direction perpendicular to the cylinder center axis.
