BELT TENSION ADJUSTMENT MECHANISM

Japanese Patent JP2015113874

A

PROBLEM TO BE SOLVED: To further surely suppress fluttering of a belt, and to further surely equalize belt tension.SOLUTION: A belt tension adjustment mechanism comprises: a first pulley 1a connected to an output shaft 1b of an engine; a second pulley 2a connected to auxiliary equipment; a third pulley 3a connected to the other auxiliary equipment; a belt 5 which is wound around the respective pulleys 1a, 2a and 3a; a first tension pulley 11 arranged at an upstream side of a traveling direction of the belt 5 with respect to the second pulley 2a; a second tension pulley 12 arranged at a downstream side while facing the first tension pulley 11; a third tension pulley 17 arranged between the first pulley 1a and the third pulley 3a; a first arm 11b which pivotally supports the first tension pulley 11; a second arm 12b which pivotally supports the second tension pulley 12; a connection part 14 which connects the first arm 11b to the second arm 12b; and first energization means 15 which energizes the connection part 14 and the third tension pulley 17 to a side at which they approach each other.
