  In the present paper we construct explicitly the intertwining differential
operators for the Jacobi algebra ${\cal G}_2.$ For the construction we use the
singular vectors of the Verma modules over ${\cal G}_2$ which we have
constructed earlier. We construct the function spaces on which the operators
act. We display two versions of the left (representation) action and the right
action. The latter is inserted in the singular vectors to provide the
intertwining differential operators.
