Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a belt transmission system capable of realizing stable transmission even in equipment whose center distance varies by vibration or the like while reducing a belt initial tension.SOLUTION: A belt transmission system 1 comprises: a drive pulley 3; a driven pulley 5; an endless belt 11; and a first idler 7 and a second idler 9. The first idler 7 is fixed in a state of pressing the belt 11 to the drive pulley 3 on a tension side of the drive pulley 3, and the second idler 9 can press the belt 11 to the drive pulley 3 on a loose side of the drive pulley 3. Transmission of power to the driven pulley 5 is turned on or off depending on whether to contact the second idler 9 with the belt 11.SELECTED DRAWING: Figure 1 【課題】ベルトの初張力を小さくしつつ、振動等によって軸間距離が変動する機器においても安定した伝動を実現するベルト伝動システムを提供する。【解決手段】ベルト伝動システム１は、駆動プーリ３と、従動プーリ５と、無端状のベルト１１と、第１のアイドラ７及び第２のアイドラ９とを備える。第１のアイドラ７は、駆動プーリ３の張り側においてベルト１１を駆動プーリ３に押し付けた状態で固定され、第２のアイドラ９は、駆動プーリ３の緩み側においてベルト１１を駆動プーリに押し付け可能となっている。第２のアイドラ９をベルト１１に接触させるか否かにより従動プーリ５への動力の伝達がオン又はオフになる。【選択図】図１
