Abstract: An arm head of a windshield wiper device is provided on a backside thereof with an undulated groove formed by sidewalls. The sidewalls have plural hill portions protruding in opposite directions alternately in a width direction of the arm head so as to be opposed to one another in a longitudinal direction thereof. Tops of the hill portions on one width side of the arm head are integrally provided at upper surfaces thereof with projections extending perpendicularly to a depth direction of the groove to overhang the groove. A hose for delivering washer liquid to a washer nozzle is accommodated in the groove and firmly held by the hill portions and the projections without using an extra part such as a clip.

Abstract: A windshield wiper device for a vehicle, for wiping the windshield of the vehicle, comprises at least one windshield wiping unit. The windshield wiping unit comprises a pivot holder attached to the body of the vehicle and having a cylindrical bearing part, a pivot shaft extended through and supported for turning in the bearing part on the pivot holder, a wiper arm having a base end part fixed to an outer end part of the pivot shaft, and a wiper blade assembly having a wiper blade and connected to the free end of the wiper arm. The pivot shaft is restrained from axial movement into the bearing part of the pivot holder by a retaining ring put there on and seated on an outer end surface of the bearing part of the pivot holder. The retaining is fractured or deformed to permit the pivot shaft to move axially into the bearing part when an axial force exceeding a predetermined level is exerted on the pivot shaft.
