Claim:
A pulley for a washing machine, wherein the pulley is coupled to a shaft that rotates a drum of the washing machine, and wherein a power transfer member transfers power from a motor of the washing machine to the pulley, the pulley comprising: a first member which is configured to be coupled to the shaft of a washing machine, wherein the first member comprises: a coupling part that couples the first member to the shaft; and at least three protruding parts that protrude from the coupling part in equally spaced radial directions; and a second member that is attached to the first member, wherein the second member comprises: a rim that is configured to receive the power transfer member; and at least three spokes that are coupled to the rim and to corresponding ones of the at least three protruding members, wherein each of the at least three protruding parts are inserted into a center of a corresponding one of the spokes such that a rotational force imparted to the rim by the power transfer member can be transferred to the coupling part, wherein an interface between the at least three protruding parts and the corresponding spokes spreads the rotational force imparted by the power transfer member, and wherein each protruding part extends at least a portion of the way up the length of a corresponding spoke.
