Abstract
Disclosed is a spacer of a windshield wiper for a vehicle including an upper panel, a pair of side panels extending downwardly from opposite lateral ends of the upper panel while defining a receiving space therebetween, the side panels being centrally formed with through holes, respectively, and annular protrusions protruded, toward each other, from the side panels around the through holes, and adapted to be fitted in through holes formed at an element of the windshield wiper to be assembled with the spacer, respectively. Each of the protrusions has a tapered structure having a diameter gradually reduced toward a free end of the protrusion, while having an annular step formed at the free end of each of the protrusions, and a plurality of slits formed at the annular step. In accordance with this structure, it is possible to prevent the spacer from being separated from an associated element of the windshield wiper upon assembling the elements of the windshield, while increasing the clamping force of the spacer, thereby minimizing the clearance defined between the spacer and the associated element.
