Claims

[Scope of utility model registration request]

first each having a cross-sectional shape having substantially upright side walls and a top wall connecting the top ends of the side walls;
and a coupling device for pivotally coupling the second yoke member to each other, the top wall and the first side walls surrounding the outer surfaces of the top wall and the side walls of the first yoke member;
a bottom wall extending in a direction approaching each other from the lower ends of the first side walls; It includes a connecting member made of synthetic resin having a cross-sectional shape and having second side walls that engage with the outer surface of the wall, and the side walls of the first and second yoke members have substantially semicircular recesses that open downward. A protrusion is provided on the upper surface of the bottom wall of the connecting member and engages with the recess of the first yoke member to inhibit relative longitudinal movement between the first yoke member and the connecting member. and a second protrusion that engages with the recess of the second yoke member is provided on the inner surface of the second side walls of the connecting member, and a first yoke is provided on the top wall of the second yoke member. A yoke member connecting device for a vehicle wiper, which is provided with an arc-shaped protrusion that is slidably supported by the inner surface of the top wall of the member.
