To provide a power transmission device for a lever hoist, which can achieve power saving during an operation of a lever hoist.SOLUTION: A power transmission device 100 for a lever hoist comprises: casings 110, 120, 130; input means 140 which is provided so as to be rotatable with respect to the casings 110, 120, 130 and to which a driving force is input from an electric screwdriver 300; reduction gears 150, 170 that reduce the driving force from the electric screwdriver 300; and a coupling part 190 that receives the driving force transmitted through the reduction gears 150, 170 to rotate. The coupling part 190 includes an irregular engaging part 194 which is engaged with an idling grip 60 to integrally rotate. The casings 110, 120, 130 include a locking mechanism 200 which is detachably attached to a plurality of connection means N1 for connecting a pair of frames 31, 32 with opposing spaces provided and which is for locking the attached state of the frames 31, 32.SELECTED DRAWING: Figure 6
