Zusammenfassung:	The utility model provides a tensioner, and belongs to the technical field of tensioners. The problem of how to eliminate reverse damping of the tensioner in the prior art is solved. A tensioner comprises a belt wheel assembly, a swing arm, a main spring and a base, one end of the swing arm is connected with the belt wheel assembly, the other end of the swing arm is rotatably connected to the base, one end of the main spring acts on the base, the other end of the main spring acts on the swing arm, and the tensioner further comprises an auxiliary spring arranged in the base. One end of the auxiliary spring acts on the swing arm, the other end of the auxiliary spring acts on the base, when the swing arm rotates in the forward direction, the auxiliary spring can be driven to twist in the forward direction, so that the auxiliary spring expands in the radial direction and abuts against the base, and when the swing arm rotates in the reverse direction, the auxiliary spring can be driven to twist in the reverse dire
