Claims

[Claims for Utility Model Registration] 1. A wiper arm having a stopper member which is supported movably in the lateral direction on the arm head and selectively locks or unlocks the wiper arm by the movement, and A wiper arm comprising a spring member that automatically moves the member to an unlocked position. 2. Claim 1, wherein the spring member is integrated with a plate spring that cooperates with the stopper member to selectively lock or unlock the wiper arm in response to movement of the stopper member. The wiper arm described in . 3. A plate spring that cooperates with the stopper member to selectively lock or unlock the wiper arm in response to movement of the stopper member is provided with a plate spring that prevents the surface of the stopper member from directly contacting the arm head in the locked state. The wiper arm according to claim 1 or 2, further comprising a flange that allows the wiper arm to rotate. 4. The plate spring that cooperates with the stopper member to selectively lock or unlock the wiper arm in response to movement of the stopper member is provided with a flange that prevents rotation of the plate spring. The wiper arm according to claim 1 or 2.
