    Abstract: In a wiper device for vehicles, a wiper blade is rotatably held on a retainer of a wiper arm through a holding axis. A slider is integrated with an end of a primary lever of the wiper blade. The slider is arranged at a position being shifted toward the wiper arm from the holding axis. The retainer has a longitudinal base wall and a first and second side walls extending from opposite side edges of the base wall, to have substantially a U-shaped cross-section opening toward a wiping surface. A slider base, a posture maintaining portion and the end of the primary lever are provided to be retractable in a U-shaped cavity of the retainer. While the wiper blade is lifted with the slider, the wiper blade is held at a predetermined posture with respect to the retainer.
