Abstract
A rotary tool includes a driving power source, a spindle formed in a columnar shape extending to a first side of an axial direction, a main hammer including a hammer pawl, an anvil including an anvil pawl engageable with the hammer pawl, a cylindrical secondary hammer disposed so as to cover an outer circumference of the main hammer, a round-columnar pin having an end portion on a second side of the axial direction positioned between the main hammer and the secondary hammer, an impacting mechanism disposed on the spindle so as to support the main hammer, and a casing. At least one end portion of the pin in the axial direction is supported in a radial direction of the pin by at least one of the spindle or the casing in such a manner that a rotation axis of the secondary hammer coincides with a rotation axis of the spindle.
