Abstract: The limb for an arrow throwing device, e.g. a bow or a crossbow, includes an upper portion, a lower portion, and an intermediate portion arranged between the upper portion and the lower portion. The upper portion and the lower portion are resilient. The intermediate portion is made non-resilient, capable of moving freely and not being deformed in conditions of load exerted on the limb during use thereof. The limb and the bow or the crossbow, featuring the limbs, can ensure a high speed of the arrow and a large stroke at small dimensions of the limb.

Abstract: The split cam for a compound archery bow includes a pair of limbs, each limb having a respective loose end and at least two portions. End members are installed on the loose ends, and each end member has a pulley for a bowstring and two attachments for two cables. In between the loose ends, a first cable and a second cable are located on the same side of the bowstring. For each limb, at least one portion of the limb separates the respective pulley from at least one of the attachments for the first cable and the second cable. The portions may be of different resilience. The cam provides for convenient operation of a compound archery bow, increases initial speed of an arrow when shooting, and increases strength and reliability.
