要約
(EN)

PROBLEM TO BE SOLVED: To provide a tensioner unit for an auxiliary machinery belt which needs only a small installation space.

SOLUTION: A structure includes: a swing arm 2 which is supported so as to swing around a fulcrum shaft 4; a tension pulley 3 supported by the swing arm 2; a spring contact pin 34 and a damper contact pin 41 which are fixedly provided; a compression coil spring 30 which presses the spring contact pin 34 so as to bias the swing arm 2 with reaction force received by the spring contact pin 34; and a hydraulic damper 31 which is attached to the swing arm 2 so as to contact with the damper contact pin 41. The structure is adopted in a tensioner unit A for an auxiliary machinery belt.
