Possible existence of bound states of a charmed baryon, I > (c) , I pound (c) , I pound* (c) with a nucleon, N, as well as two charmed baryons, I > (c) I > (c) , etc., are examined in the meson exchange potential approach. The heavy quark spin symmetry induces a strong tensor coupling between I > (c) N, I pound (c) N and I pound* (c) N states, which causes a bound state of I > (c) N (J = 0(+) and 1(+)) states. Such a bound state is also seen in the spin-singlet I > (c) I > (c) channel, which resembles the H dibaryon in the strange sector.
