Abstract

See full text

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