摘要 A power tool includes a housing including: a body part having a substantially cylindrical shape and extends in a front-rear direction; and a handle part connected to the body part. The body part includes: a driving source; a power transmission mechanism part configured to transmit a driving force of the driving source; and a tip tool holding part to which the driving force of the driving source is transmitted from the power transmission mechanism part. The handle part includes a switch. A top part protruding from a surface of the handle part is formed on a side surface of the handle part along a longitudinal direction of the handle part. At least a portion of the top part is arranged at a position deviating rearwards from a center of the handle part in the front-rear direction.
