In a resin granulating apparatus of the present invention, a bracket extending in the outward radial direction over an outer peripheral surface of a sleeve is provided for the sleeve for rotatably supporting a cutter shaft of a cutter for shearing a material extruded from a die. Stopper means cooperating with the bracket to regulate movement of the sleeve toward the die and moving a regulation position in the axial direction is provided on the radially outer side over an outer diameter of the sleeve. With such a configuration, installation space is compactified so as to additionally provide the stopper means in the existing facilities, and a position of the cutter relative to a die surface is precisely adjusted so as to stably produce a pellet of a best shape.
