PROBLEM TO BE SOLVED: To provide a belt tension adjusting jig of a door driving mechanism capable of limiting a biased load applied to a shaft of a driven pulley during the tension adjustment of a belt, to a small value.SOLUTION: The belt tension adjusting jig of a door driving mechanism includes: an adjustment bracket 30 which has a pulley support part 32 for supporting a driven pulley 14, and a standing part 33 capable of being struck by a striking tool, and which can apply tension to a belt 15 through the driven pulley 14; a fixed part 40 to be fixed to a door pocket 10; and a push bolt 41 held by the fixed part 40, for moving the adjustment bracket 30. The belt tension adjusting jig also includes a movable part 42 mounted on the fixed part 40, for holding the push bolt 41, and capable of being moved with respect to the fixed part 40, by rotation of the push bolt 41. The movable part 42 includes: a first pressing part 43 capable of pressing the standing part 33 of the adjustment bracket 30; and a second pressing part 44 capable of pressing the pulley support part 32.SELECTED DRAWING: Figure 3
