摘要： A power tool which has an anvil 20 that is rotated by a hammer 22 and is housed in a housing, and rotates an output shaft 18 is provided. The anvil 20 and the output shaft 18 are integrally formed into one unit, and a carrier 33 that is rotatable relative to the anvil 20 by a predetermined angle on the same axis is provided. On one portion of an outer circumferential surface of the anvil 20, a relief surface 20a is formed. Cut-out portions 33b are formed at positions opposed to each other of a carrier 33, and by allowing an engaging pin 37 to be interposed therein, a locking mechanism that limits the relative rotation between the anvil 20 and a lock ring 38 is prepared. When the tool main body is manually rotated while the hammer 22 is being stopped, the engaging pin 37 limits the relative rotation between the anvil 20 and the lock ring 38. The locked state between the anvil 20 and the lock ring 38 is released immediately when the rotation of the motor 4 is started.

摘要： In a cleaning machine provided with a main body which discharges cleaning liquid by a pump and a cleaning gun which is connected to the main body, the cleaning machine has: an electric motor which receives electric power supply from a battery pack and which drives the pump; and a control circuit which changes a rotating speed of the electric motor so as to increase/decrease the discharging pressure of the cleaning liquid. When the voltage of the battery pack is decreased down to a predetermined second voltage higher than a predetermined first voltage at which the electric power supply to the electric motor is stopped, the largest discharging pressure of the cleaning liquid is decreased to be lower than a current-state discharging pressure thereof.
