。[Claims for Utility Model Registration] In a hollow crankshaft in which an axial through hole is formed in each of the journal part and the crank pin part, a pair of cup-shaped plugs are inserted into each of the through holes so that the opening side faces the hollow crankshaft. They are fitted together to form a passage inside the plug body, and the passage of the plug body fitted in each of the through holes is communicated with a crank arm portion that connects the journal part and the crank pin part. A pipe hole is bored and further communicates the outer periphery of the journal part with the passage of the plug fitted in the through hole of the journal part, and the crank pin part and the through hole of the crank pin part. A tube hole communicating with the passage of the plug body fitted to the hollow crankshaft is bored in a direction perpendicular to the axial direction of the hollow crankshaft, and a hole is formed in each of the tube holes to communicate with a passage in the plug body on the circumferential surface. 1. A hollow crankshaft, characterized in that an oil hole is formed inside by fitting a pipe member having a slit hole in a corresponding position.
