Kuipers and Veldman conjectured that any 3-connected claw-free graph with order and minimum degree +6 10 is Hamiltonian for sufficiently large. In this paper, we prove that if H is a 3-connected claw-free graph with sufficiently large order , and if (H) +5 10 , then either H is hamiltonian, or (H) = +5 10 and the Ryj
