A windshield wiper assembly, comprising:

• a housing having a top surface and a side surface;
• a projection projecting in a first direction from the top surface, the projection having a through hole at a center of the projection, a longitudinal axis of the through hole being parallel to the first direction;
• a mounting bracket integrally extending from the side surface, the mounting bracket having:
• a first end boated at the side surface, the first end having:
• a first top end surface;
• and
• first and second longitudinal end surfaces opposite to each other;
• a second end located away from the side surface, the second end having:
• a second top end surface;
• and
• the first and second on longitudinal end surfaces;
• and
• a semi-cylindrical bottom connecting between the first and second ends, the semi-cylindrical bottom including the first and second longitudinal end surfaces;
• and
• a first rib integrally extending from the top surface in the first direction, the first rib integrally extending from a side of the projection to the first top end surface and the first longitudinal end surface of the mounting bracket in a first rib extending direction,
• wherein the rib has a constant height relative to the top surface from the side of the projection to the mounting bracket.
