具のクラッチ機構。A clutch plate 10 and a case 11 are attached to a gear shaft 3 that transmits the rotational force of the drive shaft to the bit side, with gears 7 and steel balls 9 interposed therebetween, facing each other in a non-rotating manner and slidable in the axial direction. In the clutch mechanism, the torque can be adjusted by adjusting the amount of compression of the compression spring 15 interposed between the guide plate 12, which is non-rotatable and slidably supported in the axial direction, using a cam 16 in multiple stages. Each cam surface 17. is provided in several stages with different radii from the center 0 of the cam shaft 16a. ,17□,173°17
A clutch mechanism for an electric tool such as a screwdriver, characterized in that 4 is located on the spring load action line of a compression spring interposed to act on the camshaft center O, and is provided at right angles thereto.
