摘要： A bow limb construction (51) includes a bushing (101) for use in mounting an archery bow limb (54) to an archery bow riser (52). The bushing can include a cylinder (116) which is adapted to be received in an aperture (71) of the bow limb. The bushing can include a vertically disposed flange (118) which is adapted to be received in a slot (70) in the bow limb. The bushing includes a first hole which extends vertically through the bushing, the first hole being adapted to receive a fastener (140) for adjustably securing the bow limb to the bow riser. Preferably, the first hole comprises a bore having an elliptical cross section. A major axis of the first hole is adapted to be aligned with a longitudinal axis of the bow limb. A second hole (160) can extend transversely through the bushing and communicate with the first hole. A set screw (162) can be threaded into the second hole so that the set screw adjustably bears against the fastener to retain the fastener in an adjusted position in the first hole.
