1. In combination, first and second yoke members of a windshield wiper, each yoke member having a cross-section including generally vertically extending side walls and a generally horizontally extending top wall connecting the upper ends of the side walls, with the side walls of said second yoke member being located inside the side walls of said first yoke member and the respective side walls having holes therein aligned with corresponding holes in the other side walls, and a device for pivotally connecting said first and second yoke members and being constituted by a pivot pin extending through the aligned openings in the side walls of said first and second yoke members, said pivot pin having the cross-section extending between the side walls of the second yoke member divided into a plurality of portions which are separated from one another in the radially outward direction for forming a large diameter portion which tightly engages with the inner circumference of said aligned openings in the side walls of said second yoke member, thereby preventing movement of said pivot pin in the axial directions, and the opposite ends of said pivot pin being substantially flush with the outer surfaces of the side walls of said first yoke member.
