Claims

[Scope of utility model registration request]

A high-speed rotation shaft connected to a drive motor, a low-speed rotation cylinder concentric with the drive motor connected to the drive motor via a reduction mechanism, and an output member disposed on the same axis as the high-speed rotation shaft. A first clutch member is disposed between the output member and the high-speed rotation shaft, and the first clutch member is only allowed to move axially relative to the output member and is pressed against the high-speed rotation shaft by a first spring. An engagement pawl is formed on the engagement surface between the member and the high-speed rotation shaft to disengage and advance the first clutch member when high torque is applied to the output member, and on the outer periphery of the first clutch member, the engagement pawl is formed to move the first clutch member forward when high torque is applied to the output member. A second clutch member that only allows axial movement with respect to the rotating cylinder is disposed, and this second clutch member is
A rectangular engagement pawl is formed on the engagement surface of the clutch member and the output member, and a rectangular engagement pawl is formed between the first clutch member and the second clutch member to transfer the force acting on the first clutch member in both the front and rear directions to the first clutch member. 2. A nut runner, characterized in that a pair of second and third springs having a weaker repulsive force than the first spring, which are transmitted to two clutch members, are disposed.
