PROBLEM TO BE SOLVED: To provide a tensioner device for suppressing an increase of friction while suppressing the vibration of a timing chain. SOLUTION: The tensioner device 10 is provided for imparting tension to the timing chain 5 for an engine. It comprises a hydraulic pump 14 for generating hydraulic pressure in accordance with the rotation of a crank shaft 21, a first tensioner 130 for imparting greater tension to the timing chain 5 as hydraulic pressure supplied from the hydraulic pump 14 is higher, and a second tensioner 150 for imparting tension to the timing chain 5 when hydraulic pressure from the hydraulic pump 14 is low, while imparting smaller tension to the timing chain 5 when the hydraulic pressure from the hydraulic pump 14 is high than when the hydraulic pressure is low.
