The characteristics of the auto-tensioner of the present invention resides in a second reservoir chamber 24 which resides within a plunger 11 extending toward inside of a spring 15. Accordingly, without changing the whole length of a cylinder 10, sufficient amount of operating oil can be reserved and the smooth flow of operating oil into a pressure chamber 23 from the second reservoir 24 chamber can be conducted.
