PROBLEM TO BE SOLVED: To enable a stable arrangement state to be maintained when hoses in two systems are arranged in an arm body, and jetted cleaning fluid to be accurately applied without interference with a wiper blade.SOLUTION: An arm body 16 has a U-shaped cross section in a direction orthogonal to the arm longitudinal direction, and a first system hose 40 and a second system hose 42 are arranged therein. A horizontal bent part 28 bent to one side in the arm width direction is formed on the tip side in the longitudinal direction of the arm body 16. A second nozzle 46 is arranged on the tip side with respect to the horizontal bent part 28 of the arm body 16 and ejects the cleaning fluid to the travel direction side of a wiper blade 14 in the first half of reciprocation. A first nozzle 44 is arranged on the intermediate side in the longitudinal direction of the arm body 16, and ejects the cleaning fluid toward the travel direction side of the wiper blade 14 and the base end side with respect to the longitudinal direction center of the wiper blade 14 in the second half of reciprocation. |
