Abstract: A fastener driving tool (1) includes a housing (2), a motor (31), a plunger (63), a spring (62), a drum (51), and one of a cable (52) and a sheet member. The motor is provided in the housing. The plunger is provided in the housing for impacting a fastener in a fastener driving direction. The spring urges the plunger in the fastener driving direction. The drum is rotatably supported in the housing and is rotationally driven by the motor. The one of a cable and a sheet member is capable of being wound over the drum and has one end fixed to the drum and another end acting on the spring for transmitting a driving force of the motor to the spring. The spring is configured to accumulate a resilient energy therein for impacting the fastener by the plunger. The resilient energy of the spring is accumulated by forcible resilient deformation thereof as a result of winding of the one of the cable and the sheet member over the drum rotationally driven by the motor.
