PURPOSE:To enable a wiper to wipe off up to the periphery of a glass by enabling a rubber member which is directly held by a yoke lever to follow a glass surface having a relatively large curvature. CONSTITUTION:A primary lever 3 which is a first supporting member, is rotatably installed on a clip 2 on the end part of an arm piece member 1. Both end parts of a rubber member 5 which is brought into contact with, and wipe off, a glass surface, are directly held by yoke levers 4. This yoke lever 4 is connected to the primary lever 3 with a set of two yoke supporting levers 6a, 6b, or a third supporting member, which are crossed each other, and the connecting part is rotatably installed by means of a pin 7.
