Abstract

A driving tool drives a fastener by a striking mechanism which is operated by a fluid. The driving tool includes a trigger, a contact arm, a contact lever and a regulator. The trigger and the contact arm receive manipulations and the contact lever switches operating states of the striking mechanism according to operations of the trigger and the contact arm. The regulator switches operating states of the contact lever according to the contact arm. The regulator includes a regulation member and a controller. The regulation member regulates the contact lever at an operation standby position where the contact lever is operated by the contact arm. The controller operates the regulation member and includes first and second cylinders. The first cylinder operates the regulation member. The second cylinder to which a fluid operating the striking mechanism is partially supplied and generates a driving force for driving the first cylinder.
