An objective is to provide a technique to securely protect the striking tool even when the striking tool inadvertently falls down. A striking tool including a rotating shaft relatively rotatably connect a main body with a handle, a first elastic member reducing transmitting of vibration from the main body to the handle in a case that the handle relatively rotates to the main body, wherein the handle includes a battery mounting portion to which battery to drive the motor is attachable and the handle is arranged to relatively move to the main body across the rotating shaft, and an adjuster such that the relative movement amount of the handle to the main body in a predetermined direction is adjusted to be larger than the relative movement amount in a direction other than the predetermined direction.
