The present invention relates to a novel coupling structure of a clutch for an overrunning pulley embedded in an automotive overrunning alternator pulley which operates in a decoupled state with respect to rotational irregularity of a crank shaft of a combustion engine and inertia of an alternator while driving. The coupling structure of a clutch for an automotive overrunning alternator pulley according to the present invention comprises: a socket stopping recess (311) formed on an end on a wider side (L-2) of a wedge-shaped engagement recess (310); spring coupling sockets (420) which comprise assembly protrusions (422) to assemble coupling plates (450) on both sides of the wider side of the wedge-shaped engagement recess (310) on which the socket stopping recess (311) is formed and an elevated unit (421) disposed on the socket stopping recess (311) to accommodate in a customized shape, and are embedded in the wider side of the wedge-shaped engagement recess (310); a plate spring (410) and a roller (320) which are disposed on one side of the spring coupling sockets (420) in which the wedge-shaped engagement recess (310) is embedded, and comprise an elastic unit (411) curved in a smooth radius of curvature; and a side coupling plate (450) which has a plurality of mounting recesses (451) to maintain a gap between the plurality of spring coupling sockets (420) required in a circumferential section and be bundled in a set, and is assembled on both sides of the spring coupling sockets (420) comprising the assembly protrusions (422).
