Claims

[Claims for Utility Model Registration] (1) A wiper arm is formed by pivotally attaching a retainer 26 to the other end of an arm head 24 rotatably attached to the vehicle body, and a wiper arm is formed between the arm head 24 and the retainer 26. A tension spring 38 is tensioned so that the tension force of the tension spring 38 causes the wiper blade 30 attached to the other end of the retainer 26 to be pressed onto the surface to be wiped, and there is a gap between the arm head 24 and the retainer 26. Equipped with a compression spring 40,
As the opening degree θ of the surface to be wiped between the arm head 24 and the retainer 26 changes, the direction in which the biasing force of the compression spring 40 acts on the rotation axis of the shaft attachment portion of the arm head 24 and the retainer 26 changes. A wiper arm structure for a wiper for a vehicle, characterized in that the pressing force of the wiper blade 30 against the surface to be wiped is made uniform by this. +2) The guide member 42 of the compression spring 40 is pivotally supported on the arm head end 52 on the outside of the rotation axis of the shaft attachment portion of the arm head 24 and the retainer 26, and the guide member 42 of the compression spring 40 is rotatably supported on the shaft support. The wiper arm structure according to claim (1) of the registered utility model, in which the moving shaft is swingable. (3) Registration of a utility model in which the rotation axis of the guide member 42 is swingable within an elongated hole 54 formed in an arc shape around the rotation axis of the shaft attachment portion of the arm head 24 and retainer 26. A wiper arm structure according to claim (2).
