Claims

[Scope of utility model registration request]

The first-stage housing and the second-stage housing are placed in a flexible and extensible relationship in parallel, and the first-stage housing is connected and supported by a reciprocating swing link shaft connected to the wiper drive source side. Inside the stage housing, there is a non-rotating body that is concentric with the link shaft and fixedly supported outside the housing, and a non-rotating body that is concentric with the output shaft and supported at a part spaced apart from the link shaft. A fixed output-side rotating body is disposed, the output-side rotating body is operatively linked to the non-rotating body so as to be able to perform planetary motion at a required rotation ratio, and the second-stage housing is connected to the second-stage housing. It is connected and supported by the output shaft protruding from the first-stage housing, and within the second-stage housing is provided concentrically with the output shaft portion,
A non-rotating body fixedly supported by the first stage housing, and a rotating body supported at a portion spaced apart from the output shaft portion and concentric with the wiper arm shaft and fixed to the arm shaft are disposed. A two-stage bending/extension type window wiper device characterized in that a rotating body on the arm shaft side is operatively linked to a non-rotating body on the output shaft side so as to perform planetary motion at a required rotation ratio.
