It is an object of the invention to provide a power tool having a rational structure. A representative power tool is provided to have a tool bit a power tool body, a motion converting mechanism housing chamber, a motion converting mechanism and a clutch mechanism. The power tool further includes a switching member, an opening, a rotating member, a switching operation transmitting mechanism and an actuating member. The switching member is disposed on an upper surface of the power tool body and can be manually operated by a user. The opening is provided to connect the motion converting mechanism housing chamber and the outside. The rotating member can rotate while closing the opening. The switching operation transmitting mechanism is disposed outside the motion converting mechanism housing chamber to connect the switching member to the rotating member and to transmit the switching operation effected by the user's manual operation of the switching member to the rotating member. The rotating member includes the actuating member that extends into the motion converting mechanism housing chamber to switch the clutch mechanism between the power transmission state and the power transmission interrupted state.
