SUBJECT of the Invention The entanglement of the locking member by a cogging torque is relieve|moderated， without worsening the operativity of the lock|rock and unlocking by a user. PROBLEM to be solved It is an electric tool， Comprising: A housing and the electric motor which is arrange|positioned inside a housing and has a permanent magnet， The shaft which is rotatably provided in the surroundings of an axis line with respect to a housing， and transmits the motive power from an electric motor， The locking member which locks rotation of a shaft by being provided so that it can move between a locked position and an unlocked position at the time of the no-energization of an electric motor， and engaging with a shaft by a locked position， When a locking member exists in a locked position， the abutting member which gives the force of the opposite direction to a locking member with respect to the torque of the surroundings of the axis line which originates in the permanent magnet of an electric motor and starts a locking member is provided.
