Abstract
A fastener driving tool includes: a driver blade which is driven by compressed air so as to move in a vertical direction for striking a fastener such as a nail, an injection hole which guides said driver blade and forms a passage for the compressed air to be exhausted along with the movement of the driver blade, and a magazine for supplying the fastener to said injection hole, wherein an exhaust passage through which an interior of the injection hole is communicated with the atmosphere is provided between a lower end of the driver blade when the driver blade is positioned at a top dead center and a head part of the fastener which has been supplied into the injection hole.
