Abstract: The representative impact tool has a motor, a driving mechanism, a body housing and a handle, and part of the motor and part of the handle are disposed on an axis of a tool accessory. The impact tool has an outer housing that is disposed to cover the outside of the body housing and connected to the body housing via an elastic element so as to be allowed to move with respect to the body housing in an axial direction of the tool accessory, and the handle is integrally connected to the outer housing. The body housing has an exposed region in which at least part of a region of the body housing corresponding to at least one of the motor and the driving mechanism, is not covered by the outer housing.

Abstract: An object of the invention is to provide an impact tool improved in vibration-proofing structure of a handle. A representative impact tool has a tool body and handle. The handle has a handle body and pair of grips that extend in a direction crossing an axial direction of a tool accessory, designed to be held by user's right and left hands. The handle body has a first part to which the grips are connected in a fixed manner and a second part that is connected to the tool body in a fixed manner. The first part is supported against the tool body via an elastic member and is allowed to move with respect to the tool body and the second part while being biased by an elastic force of the elastic member. A current supply cable, supplying current to a motor, is installed on the second part.

Abstract: A hammer drill serving as an impact tool is provided with a crank housing that accommodates a crankshaft, and a cylinder accommodated in the crank housing. Receiving portions that receive the cylinder which is pressed rearward are provided at multiple locations of the crank housing in the front-rear direction. At least one of the receiving portions is disposed to receive the rear-end portion of the cylinder. A portion of the cylinder, which is received by another one of the receiving portions is a circlip (circumferential member) made of a metal.
