Abstract

A hydraulic tensioner includes a tensioner body having a through hole formed therein, a bottomed cylindrical plunger inserted into the through hole of the tensioner body so that the cylindrical plunger is movable in an axial direction of the through hole, a cylindrical inner sleeve inserted inside the plunger, and a tensioner cap attached to one end of the tensioner body and having a first surface in contact with a proximal end of the inner sleeve. A first hydraulic chamber is formed between the inner sleeve and the plunger, and a second hydraulic chamber that stores oil to be supplied to the first hydraulic chamber is formed inside the inner sleeve. The first surface of the tensioner cap has a plurality of grooves that each connect between outside of the inner sleeve in a radial direction and the second hydraulic chamber.
