Claim 16:
17. An impact tool comprising:
a motor;
an impact mechanism configured to be driven by the motor and thereby rotated about an output rotational axis extending in a front-rear direction;
an anvil having an anvil shaft disposed forward of the impact mechanism in the front-rear direction; and at least one anvil projection that protrudes radially outward from a rear-end portion of the anvil shaft and is configured to be impacted by the impact mechanism in a rotational direction to be driven about the output rotational axis;
a hammer case, which houses the impact mechanism;
a main-body housing disposed rearward of the hammer case in the front-rear direction and fixed to the hammer case;
a grip housing having at least a portion disposed rearward of the main-body housing in the front-rear direction, the grip housing being coupled to the main-body housing so as to be movable relative to the main-body housing; and
at least a first straight coil spring disposed between the main-body housing and the grip housing and configured to attenuate vibration generated in the hammer case and propagating in the rotational direction about the output rotational axis.
