1. A multi-adapter for a vehicle wiper, comprising:
a coupling portion coupled to a blade; a pair of side plates protruding from the coupling portion such that the side plates are parallel to each other, wherein a hinge shaft is formed between the side plates; a plurality of pin coupling portions formed at the pair of side plates, respectively, the pin coupling portions including a plurality of pin holes each having different size and coaxially formed through the pair of side plates so that one of a plurality of arms having pins of different sizes may be selectively coupled to a corresponding side plate; and a plurality of protrusions formed on at least one of the pair of the side plates so as to maintain a gap between the arm and the pair of side plates, the plurality of protrusions having differing heights as measured from the side plates with respect to each other, wherein the protrusions protrude outwardly from at least one of the pair of side plates for contacting a corresponding arm, and wherein the protrusions comprise:
a first protrusion provided adjacent to at least one of the plurality of the pin holes and projected from at least one of the pair of side plates so as to maintain a gap between the arm and a side plate by directly engaging one side of the arm, anda second protrusion projected from at least one of the pair of side plates so as to maintain a gap with the arm by directly engaging an inner side of a securing piece disposed on the arm, thereby preventing the arm from playing in a direction opposite to the pin. |
