Abstract

A nozzle unit 34 which jets washer fluid toward a windshield is fixed to an arm piece 33 whose front end side is fitted to a hook fixing member 23e. As a result, the nozzle unit 34 can be fixed without using the fitting member adopted in the conventional case, and located closer to the hook fixing member 23e. This reduces a positional shift of the nozzle unit 34 relative to the wiper blade 20 to the minimum, thus stabilizing the injection-target locations of washer fluid on the windshield.

First claim

What is claimed is:

1. A wiper apparatus comprising:
a wiper blade for wiping a windshield;
a connecting portion disposed on the wiper blade;
an arm piece having a front end side fitted to the connecting portion;
a retainer fixed to a base end side of the arm piece; and
a nozzle unit fixed to the arm piece, the nozzle unit jetting washer fluid toward the windshield wherein
the nozzle unit includes a forward-side block and a backward-side block,
the forward-side block has a forward-side nozzle cap;
the backward-side block has a backward-side nozzle cap;
the forward-side nozzle cap and the backward-side nozzle cap are the same in structure as each other, and
the forward-side nozzle cap and the backward-side nozzle are different in position from each other in a longitudinal direction of the wiper blade, the forward-side nozzle cap has two or more injection nozzles corresponding to first injection-target locations on the windshield, and configured to jet washer fluid toward the first injection-target locations, respectively,
the backward-side nozzle cap has two or more injection nozzles corresponding to second injection-target locations on the windshield, and configured to jet washer fluid toward the second injection-target locations, respectively,
the first injection-target locations and the second injection-target locations are alternately arranged on the windshield in the longitudinal direction of the wiper blade.

2. The wiper apparatus according to claim 1 , wherein the arm piece and the nozzle unit is partially covered with the retainer.

3. The wiper apparatus according to claim 1 , wherein an injection-target location of washer fluid jetted from the forward-side nozzle and an injection-target location of washer fluid jetted from the backward-side nozzle are shifted to each other in the longitudinal direction of the wiper blade.

4. The wiper apparatus according to claim 3 , wherein a concave portion in which the arm piece is fitted is formed between the forward-side nozzle and the backward-side nozzle of the nozzle unit.

5. The wiper apparatus according to claim 1 , wherein a variable nozzle capable of varying an injection-target location of washer fluid is formed on a front end side of the nozzle unit and on a base end side of the nozzle unit in the longitudinal direction of the wiper blade.
