Claim 0:
1. 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 from the motor, the second axis (i) is parallel to the first axis and (ii) is in a front-rear direction of the power tool;
a main housing that houses the motor and the driving mechanism;
a handle housing (i) connected to the main housing via a first elastic member to be movable relative to the main housing at least in the front-rear direction and (ii) including an elongate grip part behind the main housing and extending in a direction crossing the second axis; and
a first guide part and a second guide part configured to guide relative sliding between the main housing and the handle housing in the front-rear direction,
wherein:
each of the first guide part and the second guide part includes a first engagement part and a second engagement part that are configured to engage each other to be slidable in the front-rear direction relative to each other;
the main housing has the first engagement part;
the handle housing has the second engagement part;
the second guide part is spaced apart from the first guide part and located rearward of the first guide part in the front-rear direction;
an up-down direction of the power tool is (i) orthogonal to the second axis and (ii) corresponds to an extension direction of the grip part;
the main housing includes:
a stator housing part that houses the stator; and
a first extending part (i) above the first axis and (ii) that extends rearward of the stator housing part;

the handle housing includes:
a cover part surrounding the stator housing part at least partially in a circumferential direction around the first axis; and
a second extending part (i) extending frontward from an upper end portion of the grip part, (ii) connected to the cover part and (iii) covering at least a portion of the first extending part;

a portion of the first extending part that overlaps the second extending part circumferentially has the first engagement part of the second guide part;
the second engagement part of the second guide part is inside the second extending part;
a rearwardmost end of the first extending part is rearward of a rearwardmost end of the motor shaft; and
the first engagement part of the second guide part is rearward of the rearwardmost end of the motor shaft.
