PURPOSE: A clutch pulley is provided to easily produce by not changing the sizes of other parts even if the diameter of a pulley unit wound with a V-belt gets larger to kinds of vehicles. CONSTITUTION: A clutch pulley is composed of an outer pulley(20) and a ring(30). The outer pulley includes an inner hub(22) rotatively combined by disposing a bearing to a nose unit of a housing of a compressor, a pulley unit(23) formed around the periphery of the inner hub, and a friction surface(24) for connecting the inner hub and one end of the pulley unit. A disc of a hub and disc assembly combined to a driving shaft of the compressor is absorbed to the friction surface to intermittent actions of a field coil unit. The ring is installed to the space between the inner hub and the pulley unit to fix the field coil unit. An outward flange(31) is formed at the end of the ring and installed to the outer pulley by caulking.
