A wiper arm including an arm main body pivotably connected to an arm head is provided in which the rotation angle of the arm main body is appropriately restricted while minimizing changes of the structure of the wiper arm from that of a wiper arm capable capable to be positioned in its locked back condition. A wiper arm 1 includes a retainer 3 capable of retaining a wiper blade, an arm head body 2 connected with the retainer 3 through a connection shaft 14 so that the retainer 3 is rotatable between an operational position and an upright position, and a rotation restricting member 30 pivotally connected through pivot shafts 16 provided on inner surfaces 12A of head arm sections 12 of the arm head body 2. The rotation restricting member 30 is pivotable around the pivot shaft 16 between a rotation restricting position and a rotation permitting position. In the rotation restriction position, the rotation restricting member 30 limits the rotation angle of the retainer 3 by contacting against the retainer 3. In the rotation permitting position, the rotation restricting member 30 does not restrict the rotation angle of the retainer 3. |
