Impact tool

An impact tool comprising:

• a casing that supports a tip tool;
• a moving member that is reciprocatably provided in the casing and generates impact force to be transmitted to the tip tool;
• an electric motor that is provided in the casing and has an output shaft;
• a motion converting mechanism that is provided in the casing, converts rotary motion of the output shaft to reciprocating motion, and transmits the reciprocating motion to the moving member;
• and
• a vibration reducing mechanism that is movably provided in the casing and reduces a vibration of the casing,
• wherein the vibration reducing mechanism includes:
• a supporting member that is provided to be swingable in a direction of a center line of reciprocation of the moving member with using a fixing position provided on the casing as a supporting point;
• and
• a weight that is attached to a location of the supporting member close to a free end relative to the fixing position, in a plane including the center line, a gravity center of the weight and the fixing position are disposed at mutually different locations in a radial direction of the center line, in the plane including the center line, the fixing position is disposed on a side of a gravity center of the impact tool relative to the center line, the supporting member has a hole penetrating therethrough in a direction along an axis of the output shaft, and the output shaft is inserted in the hole.
