Impact tool

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 defining a front-rear direction of the impact tool;
• a housing that houses the motor and the driving mechanism;
• and
• at least one dynamic vibration reducer, each of the at least one dynamic vibration reducer including a weight, at least one spring and a housing part, the weight being linearly movable in the front-rear direction, the at least one spring being at least either in front of or behind the weight, the weight and the at least one spring being housed in the housing part, wherein:
• the driving mechanism includes:
• a crank shaft configured to rotate by power of the motor;
• a cylinder extending along the driving axis in the front-rear direction;
• and
• a piston configured to reciprocate along the driving axis within the cylinder in response to rotation of the crank shaft;
• the housing includes:
• a motor housing that houses the motor;
• a crank housing that houses the crank shaft;
• and
• a barrel part that (i) is in front of the crank housing and (2) houses the cylinder;
• a first part of the barrel part that is integral with a remainder of the barrel part is a portion of the housing part;
• a first part of the crank housing that is integral with a remainder of the crank housing is another portion of the housing part;
• the housing part includes a cylindrical member that extends in the front-rear direction and that houses at least a portion of the weight;
• the first part of the barrel part and the first part of the crank housing are spaced in the front-rear direction and support the cylindrical member;
• the cylindrical member is a cylinder having an open front end and a closed rear end;
• the first part of the barrel part has a recess that opens rearwards;
• the first part of the crank housing (i) has a cylindrical shape and (ii) is rearward of the first part of the barrel part;
• and
• the cylindrical member is supported such that a front end portion of the cylindrical member is in the recess of the first part of the barrel part and another portion of the cylindrical member that is rearward of the front end portion is in the first part of the crank housing.
