Propulsion unit of an aircraft, comprising a structure as one with the aircraft, at least one electric motor, at least one propeller driven in rotation by the electric motor and configured to generate thrusting forces, a rigid casing configured to transmit the thrusting forces generated by the propeller and an engine mount connecting the casing and the structure, the propeller which has an axis of rotation defining a longitudinal direction parallel to the axis of rotation, a vertical longitudinal plane passing through the axis of rotation, which is vertical, and a longitudinal and horizontal direction perpendicular to the vertical longitudinal plane; the engine mount comprising: - first and second transverse link rods (68, 70) disposed on either side of the vertical longitudinal plane and each having a first end (68.1, 70.1) connected by at least one first joint (74.1, 76.1) to the structure and a second end (68.2, 70.2) connected by at least one second joint (74.2, 76.2) to the casing, each of the first and second joints (74.1, 74.2, 76.1, 76.2) having an axis of pivoting (A74.1, A74.2, A76.1, A76.2) substantially parallel to the axis of rotation, characterized in that the engine mount also comprises: - first and second thrust rods (54, 54') disposed on either side of the vertical longitudinal plane and having a first end (54.1) connected by a first thrust rod connection (56.1) to the structure and a second end (54.2) connected by a second thrust rod connection (56.2) to the casing, for each of the first and second thrust rods (54, 54'), the first and second thrust rod connections (56.1, 56.2) being separated from one another in the longitudinal direction, - a longitudinal end stop configured to limit a movement of the casing with respect to the structure in at least the longitudinal direction. - first and second transverse link rods (68, 70) disposed on either side of the vertical longitudinal plane and each having a first end (68.1, 70.1) connected by at least one first joint (74.1, 76.1) to the structure and a second end (68.2, 70.2) connected by at least one second joint (74.2, 76.2) to the casing, each of the first and second joints (74.1, 74.2, 76.1, 76.2) having an axis of pivoting (A74.1, A74.2, A76.1, A76.2) substantially parallel to the axis of rotation, characterized in that the engine mount also comprises: - first and second thrust rods (54, 54') disposed on either side of the vertical longitudinal plane and having a first end (54.1) connected by a first thrust rod connection (56.1) to the structure and a second end (54.2) connected by a second thrust rod connection (56.2) to the casing, for each of the first and second thrust rods (54, 54'), the first and second thrust rod connections (56.1, 56.2) being separated from one another in the longitudinal direction, - a longitudinal end stop configured to limit a movement of the casing with respect to the structure in at least the longitudinal direction. - first and second thrust rods (54, 54') disposed on either side of the vertical longitudinal plane and having a first end (54.1) connected by a first thrust rod connection (56.1) to the structure and a second end (54.2) connected by a second thrust rod connection (56.2) to the casing, for each of the first and second thrust rods (54, 54'), the first and second thrust rod connections (56.1, 56.2) being separated from one another in the longitudinal direction, - a longitudinal end stop configured to limit a movement of the casing with respect to the structure in at least the longitudinal direction.
