ようにしたことを特徴とする無動工具。An anvil having a vane and filling an eccentric cavity formed in a litchi with fluid is fitted between the motor part and a planetary gear reduction mechanism consisting of a sun gear, an inner gear, and a planetary gear that drives the drive shaft. A fluid-type pulse generator is provided, and the liner of the fluid-type pulse generator is rotated by the drive of the motor, the anvil is intermittently rotated, the sun gear of the planetary gear reduction mechanism is rotated, and the reaction force is generated. The receiver causes a planetary gear fixed to the member between the inner gear and the sun gear to perform planetary rotational motion to decelerate and rotate the drive shaft, and the reaction force receiver in response to the reaction force of the inner gear causes the eyelid of the member to move. A non-moving tool characterized in that a detection sensor is provided and a motor section is controlled by the output of the sensor.
