Abstract
To provide a flow path structure of a hollow tube capable of reducing facility cost and product cost by promoting assembling operability, a rocker shaft is constituted by including a tubular member having a hollow portion and a partitioning member interposed at the hollow portion of the tubular member for partitioning the hollow portion into a plurality of flow paths along an axial direction and the partitioning member is constituted by a plate member including a partitioning portion for partitioning the hollow portion into the flow paths along the axial direction and a close contact portion brought into close contact with an inner face of the tubular member.
