摘要： An oil tight type chain tensioner applies tension to a chain used in an engine. The tensioner includes a housing, in which oil is sealed, and a reciprocating rod extending from the interior of the housing to the exterior for pressing the chain. An oil seal is located between the outer circumferential surface of the rod and the inner circumferential surface of the housing. A reservoir for retaining the oil is communicated with the interior of the housing. This structure permits the oil to flow between the interior of the housing and the reservoir in correspondence with the reciprocation of the rod. The reservoir has a hole for permitting air communication from the interior of the reservoir to the exterior but restricting an oil flow from the exterior of the reservoir to the interior.
