Impact tool

An impact tool configured to linearly drive a tool accessory in a hammering-axis direction, the impact tool comprising:

• a tool-accessory holding part having a through hole extending in the hammering-axis direction and configured to hold the tool accessory inserted into the through hole so as to be movable in the hammering-axis direction;
• a body connected to the tool-accessory holding part in the hammering-axis direction and having an internal space communicating with the through hole;
• a first hammering member disposed to be linearly movable in the hammering-axis direction and configured to drive the tool accessory in the hammering-axis direction by colliding with the tool accessory;
• a circular cylindrical member disposed coaxially with the hammering-axis in the internal space;
• and
• a second hammering member disposed to be movable in the hammering-axis direction within the circular cylindrical member and configured to linearly move the first hammering member by colliding with the first hammering member, wherein:
• the tool-accessory holding part and the body are connected in the hammering-axis direction via a first elastic element so as to be movable relative to each other;
• a second elastic element is interposed between the first hammering member and the body in a radial direction with respect to the hammering-axis direction;
• the second hammering member has a circular column part having a circular column shape and has one or more third elastic elements disposed on an outer circumferential surface of the circular column part;
• and
• the one or more third elastic elements are slidable in the hammering-axis direction along an inner circumferential surface of the circular cylindrical member and configured to hold the second hammering member within the circular cylindrical member in a state in which the outer circumferential surface is not in contact with the inner circumferential surface.
