Power tool having hammer mechanism

A power tool having a hammer mechanism, the power tool comprising:

• a motor including a stator, a rotor, and a motor shaft, the motor shaft extending from the rotor and being rotatable integrally with the rotor around a first axis;
• a driving mechanism configured to perform a hammer action of linearly driving a tool accessory along a second axis using power generated by the motor, the second axis extending parallel to the first axis and defining a front-rear direction of the power tool;
• a main housing that houses the motor and the driving mechanism and that extends in the front-rear direction;
• a handle housing including a grip part configured to be gripped by a user, the handle housing being elastically connected to the main housing to be movable relative to the main housing at least in the front-rear direction;
• a movable member disposed in or on a first one of the main housing and the handle housing and configured to move in response to relative movement of a second one of the main housing and the handle housing in the front-rear direction;
• a detector disposed in or on the first one of the main housing and the handle housing, in or on which the movable member is disposed, and configured to detect pressing of the tool accessory against a workpiece by detecting movement of the movable member;
• a control device configured to control driving of the motor based on a detection result of the detector;
• and
• a first guide part and a second guide part configured to guide relative sliding movement of the main housing and the handle housing in the front-rear direction, wherein:
• the first guide part and the second guide part are spaced apart from each other in the front-rear direction, and
• the movable member and the detector are between the first guide part and the second guide part in the front-rear direction.

• a control device configured to control driving of the motor based on a detection result of the detector;
• and
• a biasing member, wherein
• the movable member is configured to be linearly movable,
• the detector is configured to detect linear movement of the movable member,
• the second one of the main housing and the handle housing has a contact part configured to move the movable member frontward or rearward by making contact with the movable member during the relative movement,
• the biasing member is configured to bias the movable member toward the contact part, and
• a straight line extending in the front-rear direction crosses the contact part, the movable member, and the biasing member
• a target to be detected by the detector is disposed on the movable member at a position offset from the straight line.
