Abstract: A tool is portable and is to be used with a grip of the tool gripped thereon. The tool includes a vibration generating device. The vibration generating device is configured to generate vibration to notify a state of a machine. The vibration generating device is disposed inside the grip. The vibration generating device is disposed to vibrate in a direction substantially orthogonal to an axial direction of the grip.

Abstract: A contact mechanism includes a contact top disposed on an outer peripheral portion of a leading end portion of a nose in such a manner that it is slidable along an axial direction of the nose, and a hollow nose top held by the contact top and including an ejection opening formed in front of an ejection opening formed in the nose in such a manner that the ejection opening of the nose top is connected continuously with the ejection opening of the nose. The contact top is connected to an adjuster mechanism through a contact arm and, at the same time, the contact top can be guided by the outer peripheral surface of the leading end portion of the nose.

Abstract: A nailing machine has a contact foot coupled to the front end portion of an contact arm which is provided along a nose section adapted to hammer a nail, such that the contact arm is slidable in a nail hammering direction. The contact foot mounting structure comprises: a U-shaped mounting pin having a pair of legs, a holding piece formed at the front end of the contact arm in which the contact foot is accommodated and held, the holding piece having a pair of inserting sections, into which respective legs of the mounting pin are inserted; and a pair of engaging sections formed at the contact foot, the engaging sections being engaging with respective legs of the mounting pin.
