Abstract: Provided is a windshield wiper arm. This windshield wiper arm includes: an arm head (10); a shank; an arm piece connected to the windshield wiper blade; a washer nozzle which sprays a washer liquid onto the wiping surface; and a hose. The hose is divided into a first hose disposed along the arm head and a second hose disposed within the vehicle body. The first hose and the second hose are connected in a manner that washer liquid can flow from one hose to the other via a joint member (70). The arm head (10) has an opening part (10A) which opens on a fastening part 11 side, and the joint member (70) is mounted to the arm head (10) in a manner that the part of the joint member (70) that connects with the second hose penetrates the opening part (10A).

Abstract: A windshield wiper arm includes: an arm piece to which a wiper blade wiping a wiping surface is connected; a hose supplied with washer fluid; and a washer nozzle connected to the hose and mounted on the arm piece on the base end side with respect to a portion connected to the wiper blade. The washer nozzle includes: a first flowpath extending in a longitudinal direction; a second flowpath connected to the first flowpath and extending in a wiping direction which intersects the longitudinal direction, and in which the wiper blade can move when wiping the wiping surface; a third flowpath connected to the second flowpath and extending in a vertical direction which is along a normal line of the wiping surface while intersecting the longitudinal direction and the wiping direction; and a fitting groove into which the arm piece is fitted and which extends along the longitudinal direction.
