摘要： A torque adjustment device is disclosed which enhances durability and in which it is easy to set a maximum torque and to perform fine adjustment while normally keeping constant a rotational force of a torque adjustment sleeve. A cylindrical clutch adjustment handle is rotatably mounted at an opening portion of a housing. A clutch case is received within the clutch adjustment handle. A plurality of slant surfaces which are different in height in the axial direction are formed in an inner circumferential portion of the clutch adjustment handle. A clutch plate is supported to the slant surfaces. Also, the clutch plate is displaceably mounted along an outer peripheral portion of the clutch case. Steel balls which are held by a clutch surface of an inwardly toothed gear are received in holes of the clutch case. A spring is interposed between an abutment plate in abutment with the steel balls and the clutch plate. A plurality of recesses are formed in a flanged portion of the clutch adjustment handle. A projection of a positioning plate is engaged with the associated recess.

摘要： A power tool comprises an outer casing, a drive motor disposed in the casing for driving a tool member, a drive shaft extending from the drive motor, an electric element of operating the drive motor, a heat radiating block secured to the drive motor, a power control element secured to the heat radiating block for controlling a rotation number of the drive motor, and a mechanism for preventing a rotation of the drive motor in engagement of the heat radiating block with the outer casing. The rotation preventing mechanism comprises an engaging member integrally formed to the heat radiating block and a member formed to the casing to be engageable with the engaging member. The power tool further comprises a speed reduction mechanism connected to the drive motor for reducing the driving speed of the drive motor and a rotation transmitting mechanism operatively connected to the speed reduction mechanism for transmitting the rotation of the drive motor to the tool member. The speed reduction mechanism includes a rotating portion having a pinion and the rotation transmitting mechanism includes a shaft having one end connected to the rotating portion of the speed reduction mechanism and another end connected to the tool member, the one end of the shaft being provided with a hole into which said rotating portion is rotatably inserted.
