Abstract

PURPOSE:To permit the application of the captioned apparatus into the equipment which receives the bad influence of magnetic material by forming one or both of the driving and trailing frictional plates from the plate members which are made of austenite steel material whose surface is applied with salt-bath nitriding treatment, thus increasing the rate of use of nonmagnetic material. CONSTITUTION:When pressurized oil is supplied through a passage 8 into a cylinder 2 formed in a driving drum 1, a piston 3 shifts in the Z direction, and a driving frictional plate 4 and a trailing frictional plate 7 are press-attached. Therefore, the power of the driving drum 1 is transmitted to an output shaft 5 through the above-described both frictional plates 4 and 7 and a clutch hub 6. In this case, one or both of the above-described frictional plates 4 and 7 are made of the austenite stainless steel material such as hot-rolled stainless steel plate, etc., and the surface is applied with the hardening treatment by the salt bath nitriding (tufftriding). Therefore, the rate of use of nonmagnetic material can be increased, maintaining the high abrasion resistance and seizureproofness, and an aimed purpose can be achieved.
