Abstract: An operating device comprises a base member, an operating member, a piston, and a coupling structure. The base member includes a cylinder bore having a cylinder center axis. The operating member is movable relative to the base member between a rest position and an operated position. The piston is movably provided in the cylinder bore and is coupled to the operating member to be pulled in a pulling direction in response to a pulling movement of the operating member from the rest position to the operated position. The operating member includes a cam surface including a curved surface. The base member includes a guide groove linearly extending in the pulling direction. The coupling structure includes a follower configured to be in contact with the cam surface to receive the pulling movement, and a guided part movably provided in the guide groove to move the follower in the pulling direction.

Abstract: A hydraulic operating device comprises a base member, an operating member, a piston, and a mounting member. The base member includes a cylinder bore, a first hose-attachment hole, and a second hose-attachment hole. The first hose-attachment hole is configured to be in fluid communication with the cylinder bore. The second hose-attachment hole is configured to be in fluid communication with the cylinder bore. The operating member is pivotally coupled to the base member about a pivot axis. The mounting member is configured to couple the base member to a handlebar. The mounting member includes a mount opening through which the handlebar is to extend. The first hose-attachment hole, the second hose-attachment hole, and the mount opening are provided on a reference plane perpendicular to the pivot axis.

Abstract: A brake caliper for a bicycle includes a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle. A brake pad is installed within the housing and is configured to move between a braking position and a non-braking position. The braking position is a location within the housing where the brake pad contacts the disc when the housing is installed on the bicycle. The non-braking position is a location within the housing where the brake pad is further from the disc than in the braking position. The caliper also includes a biasing member configured to bias the brake pad in a downstream direction within the housing with the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward.

Abstract: A piston assembly is provided for a human-powered vehicle. The piston assembly includes a main body and a primary seal. The main body is configured to be movable from a rest position to an actuated position along an actuation direction in a cylinder bore. The primary seal includes a primary seal body arranged on the main body. The primary seal body is made of a resin material. The main body includes a first part and a second part. The first part is at least partly arranged upstream of the primary seal with respect to the actuation direction. The second part is coupled to the first part to be at least partly arranged downstream of the primary seal with respect to the actuation direction. The at least one of the first part and the second part includes a support portion supporting the primary seal.
