To provide a technique that can improve workability of maintenance work for a belt and a belt driving mechanism.SOLUTION: A belt driving device comprises a movement mechanism 56 which moves a first rotor 511f among a plurality of rotors, on which an endless belt 50 is stretched, between a contact position that applies tension to the belt 50 and a separated position that reduces tension. In the device, the separated position includes: a first separated position that is parallel to a rotation axis when a direction of the rotation axis of the first rotor 511f is positioned at the contact position; and a second separated position that is inclined with respect to the rotation axis when a direction of the rotation axis is positioned at the contact position. The movement mechanism 56 is caused to pass through the first separated position when moving the first rotor 511f between the contact position and the second separated position, and not to change the direction of the rotation axis when moving the first rotor 511f between the contact position and the first separated position.SELECTED DRAWING: Figure 14 【課題】ベルトやベルト駆動機構に対するメンテナンス作業の作業性を向上させることができる技術を提供する。【解決手段】無端形状のベルト５０を張架する複数の回転体のうちの第１の回転体５１１ｆを、ベルト５０に張力を付与する接触位置と、張力を低減させる離隔位置と、の間で移動させる移動機構５６を備えるベルト駆動装置において、離隔位置は、第１の回転体５１１ｆの回転軸線の向きが、接触位置に位置するときの回転軸線と平行な第１離隔位置と、回転軸線の向きが、接触位置に位置するときの回転軸線に対して傾斜する第２離隔位置と、を含み、移動機構５６は、第１の回転体５１１ｆを接触位置と第２離隔位置との間で移動させる際に、第１離隔位置を経由させ、第１の回転体５１１ｆを接触位置と第１離隔位置との間で移動させる際に、回転軸線の向きを変化させない。【選択図】図１４
