We search for the existence of weakly bound He-He-Rb molecules. The He-He-Rb molecule is treated as a three-body system. By using hyperspherical coordinates, the Schroedinger equation for the triatomic system is solved in the adiabatic approximation. A bound state is found for each of the {sup 3}He-{sup 3}He-{sup 85}Rb, {sup 3}He-{sup 4}He-{sup 85}Rb, and {sup 4}He-{sup 4}He-{sup 85}Rb trimers, respectively. The bound state for the {sup 3}He-{sup 3}He-{sup 85}Rb molecule is a Borromean state found in a realistic molecular systems because there are no bound states in both the {sup 3}He-{sup 3}He and {sup 3}He-{sup 85}Rb dimers.
