A spring-type fastener driving tool 1 includes a plunger 8 having a blade 8a that drives in fasteners, a spring 9 that urges the plunger 8 downwards and is capable of being compressed upwards, a spring compression mechanism unit 81 that includes a drum 13 that causes the plunger 8 to move in a compression direction of the spring 9 based on rotational force of a motor 7, a reduction mechanism unit 80, and a one-way clutch 24 than prohibits reverse rotation of the motor 7. Reverse rotation of the drum 13 due to the urging force of the spring 9 is prevented by providing the one-way clutch 24 between an input side rotating shaft of the reduction mechanism unit 80 and a rotation output shaft 7a of the motor 7. |
