WINDSHIELD WIPER ARM

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.
