Claims

[Scope of utility model registration request]

A wiper for a vehicle is configured to change the wiping position on the vehicle window surface between the outward and return trips by extending and contracting the wiper arm, the wiper arm being moved between a fixed part on the shaft support side and the blade side for telescopic movement. The arm components are divided into at least two sets of arm components, and the two sets of arm components are interconnected via a relative movement mechanism capable of relative movement in the axial direction, and the relative movement mechanism is connected to a predetermined linking member. A wiper structure for a vehicle, characterized in that the windshield wiper structure is linked to a rotary link of a rotary link mechanism for operating the wiper arm through the wiper arm, and is expanded and contracted in accordance with the rotational movement of the rotary link.
