Abstract
Provided is a chain tensioner that can improve the degree of freedom in setting the oil supply position with a simple structure, can supply sufficient and necessary oil when restarted after a long time after the stop of oil supply, can entirely be made shorter and smaller, and can be produced easily with reduced cost. In a chain tensioner 100 in which a plunger 120 inserted in a plunger bore 111 of a tensioner body 110 is biased outward by biasing means 140 provided in an oil pressure chamber 101 to be extendable and contractible, an oil reservoir chamber 123 is formed on an outer side than a check valve 150 inside a plunger body 126, and a connection/adjustment groove 103 forming an oil supply space 102 is formed in an inner circumferential surface of the plunger bore 111.
