Abstract
A driving machine is provided to prevent clogging of a fastener in an ejection passage without increasing the total length of the ejection passage. A nail driving machine includes: a nose part forming an upper portion of an ejection passage through which a nail passes; a contact part being slidable along the nose part and forming a lower portion of the ejection passage; a driver blade striking a head part of the nail supplied to the ejection passage; and a guide part disposed in a lower portion of the nose part and guiding the nail passing through the ejection passage. The guide part has a guide surface inclining to protrude from a radial outer side toward a radial inner side of the ejection passage. A housing groove is formed in the contact part and the guide part enters the housing groove when the contact part slides along the nose part.
