Wiper blade assembly

A wiper blade assembly comprising:

• a contact member;
• an elastic member for supporting the contact member;
• an elongated coupling cover to be fastened to the elastic in a height direction of the coupling cover;
• and
• an elongated cover member for covering the elastic member and configured to receive the coupling cover therein in a height direction of the cover member;
• wherein the cover member comprises:
• a spoiler;
• an extended plate extended from one end of the spoiler;
• a first coupling protrusion located in a first predetermined position of the extended plate;
• and a first coupling through-hole located in a second predetermined position of the extended plate adjacent to the first coupling protrusion,
• wherein the coupling cover comprises:
• a second coupling through-hole located in an inner space thereunder;
• and a second coupling protrusion located adjacent to the second coupling through-hole,
• wherein the second coupling through-hole receives the first coupling protrusion of the cover member and the second coupling protrusion is inserted into the first coupling through-hole of the cover member while the coupling cover is fastened to the cover member in the height direction of the cover member, such that the cover member is immovably fixed to the coupling cover in opposing longitudinal directions of the cover member, and
• wherein the height direction is perpendicular to the longitudinal direction of the cover member.
