Abstract
A plungerand a springbiasing the plungeroutwardly are mounted in a cylinder chamberformed in a housing. The housingis provided with an oil supply passagecommunicating with a pressure chamberformed in the back of the plunger. The housinghas an outer diameter that is substantially constant over the entire axial length, so that such housings can be mass-produced by pressing. It is thus possible to lower the cost of the chain tensioner.
