Claims

[Claims for Utility Model Registration] 1. An arm shank having a substantially U-shaped cross section, an arm fixed to the distal end of the arm shank to support a wiper blade, and one end of which is attached to the base end of the arm shank. A support that is inserted to rotatably support the arm shank within a certain range, and a spring that is stretched between the base end of the arm and the support so as to bias the arm in a direction opposite to the locking direction of the arm. and a stopper that is slidably held in a direction orthogonal to the axial direction of the arm shank so that a portion protrudes from the edge of the support near the end of the arm shank on the back side of the support. A wiper arm device configured such that a stopper end surface contacts an arm shank end surface only when sliding in one direction, and this contact restricts the rotation range of the arm shank to a narrow range and holds the arm in a locked back state. The wiper arm according to the invention, wherein operating portions bent in a direction substantially perpendicular to the sliding direction are formed at both ends of the stopper in the sliding direction. 2. Each operation part of the stopper is characterized in that when the stopper slides in the lockback direction or the lockback release direction of the arm, the end face of the operation part and the edge of the support are on the same plane. A wiper arm device according to claim 1 of the utility model registration claim.
