Abstract

See full text

When the plunger is a game moved to a prescribed position Ph of an initial state on the upper dead point side by the drive force of the motor after the plunger is moved to the lower dead point side, the controller of a spring driven-type fastener driving tool reduces the rotational speed of the motor to a prescribed value or less based on the detection signal of the operation detection switch and then stops the slowed down motor. In order to achieve this, the plunger is stopped at a stop position of an initial state that is as close as possible to an upper dead point side drive start position and is subjected to a strong compression force by the drive spring.
