摘要： A driving tool drives a fastener by a striking mechanism. The driving tool includes a trigger, a contact arm, a contact lever and a regulator. The trigger and the contact arm receive manipulations which operate the striking mechanism. The contact lever is movable according to operations of the trigger and the contact arm and switches operating states of the striking mechanism. The regulator regulates a movement of the contact lever according to a movement of the contact arm in which another manipulation is released. The regulator operates with a fluid for operating the striking mechanism, and keeps the contact lever at an operation standby position where the contact lever is operated by manipulation of the contact arm for a predetermined time period by controlling a flow rate of the fluid.

摘要： A fastener driving tool injects a fastener from an injection passage formed in a leading end of a tool main body. The injection passage includes therein a guide portion formed along a driving direction of the fastener for guiding the fastener. The guide portion is formed by providing contours having mutually different distances from a center of the injection passage in a cross-section of the injection passage.

摘要： A striking tool includes: a driver which is provided to be slidable toward an ejecting port provided in a tip end of the striking tool so as to strike out a fastener from the ejecting port; a plunger to which the driver is coupled; a plunger urging member which is configured to urge the plunger toward the ejecting port: and a drive mechanism which is configured to move the plunger to accumulate urging force in the plunger urging member. A standby position of the plunger before striking out the fastener can be switched between a usual standby position and a standby position for maintenance closer to the ejecting port than the usual standby position.

摘要： A driving tool is provided with a nose portion 16 from which a fastener is driven out, and a contact arm 20 which is slidable along the nose portion. The contact arm 20 includes a U-type leading end portion 20a. A leading end of the nose portion 16 enters an inside of a U-type part of the leading end portion 20a of the contact arm 20 when the contact arm 20 slides toward a base end of the nose portion 16. The leading end portion of the nose portion 16 includes a receiving portion 22, 23 by which a load applied to the contact arm is received.

摘要： A fastener driving tool includes a nose portion, a supply passage and a fastener supply mechanism. The nose portion includes an injection passage for injecting a fastener. The supply passage is connected to the injection passage. The fastener supply mechanism feeds connected fasteners to the injection passage. The fastener supply mechanism includes a feed member which advances and retreats in a feed direction and which oscillates in a direction to retreat from the supply passage. The feed member includes a feed tooth which feeds the fastener to the injecting passage by engaging with a rear portion of the fastener and an auxiliary tooth which is disposed on a foot side of the fastener to prevent the fastener from deviating from the injection passage. When the feed tooth of the feed member projects into the supply passage, the auxiliary tooth projects into the supply passage longer than the feed tooth.
