てなるリンクの連結構造。 A drive side link connected to a motor and a driven side link connected to a wiper blade are fitted with a ball joint fixed to one of these links and a retainer attached to the other link. In the wiper for an automobile, the wiper blade is driven by the motor through each of the links, and the wiper blade has a substantially cylindrical shape and is located between the links on the outside of the ball joint. A rubber joint seal is attached to the O-ring part that contacts the corner formed by the base end of the ball joint and the one link, and to the flat surface of the one link that is away from the corner. a contacting lip portion is provided at one end of the joint seal; a protrusion portion that contacts a corner formed by the retainer and the other link is provided at the other end of the joint seal; A link connection structure comprising a helical reinforcing portion protruding from the outer periphery of the joint seal that applies a resilient force uniformly to the entire periphery of the openings at both ends of the joint seal.
