Abstract
An improved chain tensioner device having a small outside shape or profile and a relatively small number of components which can be assembled with a small number of steps. A tensioner body 2 slidably mounts a plunger 4 which carries a shoe 7 for engaging the chain. The shoe 7 has an extension strip 12 formed integrally therewith and extending over a guide surface 11 on the body 2 for preventing the shoe 7 from rotating about the axis of the plunger 4. A pin locking hole 13 is formed in the guide surface 11 and the extension strip 12 has a pin receiving through-hole 14 formed at a position which can be aligned with the pin locking hole 13. A stopper pin 15 is fitted through the pin receiving through-hole 14 into the pin locking hole 13, thereby locking the shoe 7 in position against movement relative to the tensioner body 2 during installation.
