ーン張力維持構造。[Scope of Claim for Utility Model Registration] In an internal combustion engine equipped with a cam chain tensioner that applies tension by bringing a presser into contact with a cam chain that is wrapped around a drive sprocket on a drive shaft and a driven sprocket on a valve drive camshaft, A cam chain tensioner is located below the oil outlet for supplying lubricating oil to the sprocket, driven sprocket, and the cam chain that meshes with these, and is disposed on the wall of the engine body adjacent to the cam chain. The tensioner includes a housing that defines a cylinder chamber, a hollow piston that is fitted into the housing so as to be freely protrusive and retractable, and whose tip presses a presser to bring it into pressure contact with a cam chain, and a rear end of the hollow piston. a check valve that partitions the inner chamber of the hollow piston from the cylinder chamber and allows hydraulic oil to flow from the inner chamber to the cylinder chamber; and a check valve that presses the rear end of the hollow piston to remove the hollow piston from the housing. The lubricating oil flows into the oil collection port formed in the upper part of the body wall of the housing on the tip side of the hollow piston, and
Cam chain tension for an internal combustion engine, characterized in that the oil enters the inner chamber of the hollow piston through an oil inlet formed in the pipe wall of the hollow piston corresponding to the oil collection port, and is used as hydraulic oil for the cam chain tensioner. maintenance structure.
