摘要： Provided is an impact type electric tool. A striking mechanism is used, which uses a hammer having striking claws that are equally arranged in the rotational direction and an anvil having struck claws. A relationship between a striking energy E, which the hammer has right before striking the anvil, and a disengaging torque TB, which is applied between the hammer and the anvil right before the hammer is disengaged from the anvil, is set as 5.3×TB
