A vehicle wiper comprises a retainer that is formed in an elongated shape open at the lower side facing toward a windshield, and that is provided so as to be capable of swinging about a shaft axis of a pivot shaft that is swung to-and-fro; a first nozzle member that is housed inside the retainer, and that is capable of ejecting washer fluid from an ejection portion; and 1 a retainer cover member that closes off an opening of the retainer, and that is formed with a window through which the ejection portion of the first nozzle member is externally exposed.

The wiper device includes a carrier element and a wiper blade with at least one longitudinal groove, in which groove the carrier element is disposed. The wiper device also includes a connecting device for pivotally connecting the wiper blade with an oscillating arm. The connecting device has spaced-apart sidewalls, each with a protrusion that extends sidewardly and outwardly. The connecting device and oscillating arm are interconnected by the protrusions pivotally and snappingly engaging into correspondingly shaped recesses of the oscillating arm. The oscillating arm has a guiding tongue engaging into a guiding groove of the connecting device. The connecting device has an asymmetric form with respect to its middle transverse plane, seen in vertical direction, in order to ensure that the wiper blade can only be mounted on the oscillating arm in a predetermined orientation of the wiper blade relative to the oscillating arm.

Casing (20) for a windscreen wiper drive rod, in particular of a motor vehicle, said casing being configured to cover et least a portion of said drive rod and comprising means for fixing to said drive rod and/or to at least one element (42) linked to said drive rod, characterised in that it further comprises support and guiding means (70) which are configured to cooperate with at least one electric cable (63) and/or at least one fluid line (64) of said windscreen wiper.

An arm head includes a head-side engagement part with which a tension spring is engaged. An arm shank includes: a pair of sidewall parts disposed opposed to each other in a wiping direction; a top wall part provided on a side opposite to the wiping surface side of the pair of sidewall parts and connecting the sidewall parts to each other; a shank-side engagement part provided between the sidewall parts and with which the tension spring is engaged; and a spring accommodating recess provided at the top wall part and capable of accommodating a part of the tension spring. When the arm shank is raised, a part of the tension spring is accommodated in the spring accommodating recess, and when the arm shank is raised and viewed from a direction in which the sidewall parts are opposed to each other, the tension spring is hidden by the sidewall parts.

A wiper device includes: lock grooves provided at an arm head and recessed toward both sides in a wiping direction of a wiper blade; and lock claws provided at an arm shank and protruding toward both sides in the wiping direction of the wiper blade. By concave-convex mating of the lock grooves and the lock claws with each other, the arm shank is restricted from rotating by degrees (about 22 degrees) or more with respect to the arm head, and a state in which the arm shank stands up by degrees (about 20 degrees), which is smaller than degrees, with respect to the arm head is maintained.
