Claim 0:
1. An impact tool, comprising:
a motor;
a driving mechanism configured to linearly drive a tool accessory along a driving axis by power of the motor, the driving axis extending in a front-rear direction of the impact tool;
a body housing that houses the motor and the driving mechanism;
a handle connected to the body housing via an elastic member to be movable relative to the body housing, the handle including a grip part configured to be held by a user;
a position detection device configured to detect when the handle is in different positions relative to the body housing; and
a control device configured to control rotation speed of the motor based on a position detection result of the position detection device, wherein:
the control device is configured to drive the motor (i) at a first rotation speed when the position detection device detects that the handle is in a first rearward position relative to the body housing and (ii) at a second rotation speed higher than the first rotation speed when the position detection device detects that the handle has moved to a second position relative to the body housing from the first rearward position, the second position being forward of the first rearward position; and
the control device is configured to reduce the rotation speed from the second rotation speed to the first rotation speed when a specified time elapses after the handle moves from the second position toward the first rearward position.
