  For an associative algebra A we consider the pair "the Hochschild cochain
complex C*(A,A) and the algebra A". There is a natural 2-colored operad which
acts on this pair. We show that this operad is quasi-isomorphic to the singular
chain operad of Voronov's Swiss Cheese operad. This statement is the Swiss
Cheese version of the Deligne conjecture formulated by M. Kontsevich in
arXiv:math/9904055.
