The device has already been proposed. (Tokugansho
No. 56-50245) The present invention is a further improvement of the prior invention, and the nozzle pipe that supports the nozzle can be rotated integrally with the wiper shaft in the hollow part of the wiper shaft that supports the wiper blade. The nozzle is rotated in the wiping direction by following the rotation of the wiper shaft, eliminating the need for links, and also rationally incorporating a leading mechanism that allows the nozzle to precede the movement of the blade. It is something.

に接続する。 A nozzle pipe 29 is fitted into the hollow part 28 of the wiper shaft 22 so as to generate a frictional force, and the nozzle pipe 29 is driven by the reciprocating rotation of the wiper shaft 22, while the upper part of the nozzle pipe 29 is connected to the base. A nozzle 10 for spraying cleaning liquid onto the window glass 6 is fixed to the upper end of the cover 30 which protrudes from the cover 30 fixed to the ring 23, and the lower part of the nozzle pipe 29 is connected to the liquid feeding tube 11.
Connect to.

上記ストツパーアングル１８に設ける。 On the other hand, as shown in FIG. 3, a stopper piece 32 is fixed to the lower part of the nozzle 29, and a stopper part 33 is attached to the stopper piece 32 to restrict the rotation angle α of the nozzle pipe 29. Provided at the stopper angle 18.
該ストツパー片３２によるノズルパイプ２９の
回動角αの終点は、第４図に示すように、ワイパ
ーアーム４の回動角θの終点手前に設定される。 The end point of the rotation angle α of the nozzle pipe 29 by the stopper piece 32 is set before the end point of the rotation angle θ of the wiper arm 4, as shown in FIG.

ル１０からウインドガラス６に洗浄液が散布され
るようになる。 If the window washer device is configured as described above, when the wiper shaft 22 is reciprocated by the wiper drive motor 1 via the links 2 and 3, the wiper blade 5 is moved by the wiper arm 4.
At the same time as the wiper shaft 22 is reciprocated, the nozzle pipe 29 fitted to the wiper shaft 22 by friction is also driven, and the cleaning liquid is sprayed from the nozzle 10 onto the window glass 6.
このとき、ノズルパイプ２９の回動角αの終点
は、ストツパー片３２とストツパー部３３とによ
りワイパー軸２２の回動角θの終点よりも手前で
ある。 At this time, the end point of the rotation angle α of the nozzle pipe 29 is located before the end point of the rotation angle θ of the wiper shaft 22 due to the stopper piece 32 and the stopper portion 33.
従つて、折返し点において回動角αおよびθの

れるので、洗浄効果が高まるようになる。 Therefore, at the turning point, the wiper shaft 22 rotates extra while slipping with respect to the nozzle pipe 29 by the angular difference β 1 , β 2 at both ends of the rotation angles α and θ. As a result, the rotational phase of the nozzle can be advanced by an angular difference β 1 or β 2 relative to the reciprocating phase of the wiper blade, and the cleaning liquid is always discharged from the nozzle 10 in advance of the movement of the wiper blade 5. Since it is sprayed onto the window glass 6, the cleaning effect is enhanced.

方向に先行させるようにしたものである。 As is clear from the above description, the present invention involves fitting a nozzle pipe to a wiper shaft that is reciprocally rotated by a motor so that it can rotate integrally with the wiper shaft, and wiping the nozzle by following the wiper shaft. At the same time, the stopper piece of the nozzle pipe is stopped by the stopper member at a position before the end point of the rotation angle of the wiper shaft, the rotation of the nozzle pipe is restricted, and the jetting direction of the cleaning liquid is adjusted to the direction of the blade. It is made to precede in the wiping direction.

を少なくすることができる。 Therefore, compared to the conventional method of spraying cleaning liquid from a nozzle fixed to the car body and wiping the windshield with a wiper blade, this method allows cleaning liquid to be sprayed over a much wider area and has good cleaning efficiency. consumption can be reduced. Furthermore, since the nozzle pipe is inserted through the hollow wiper shaft, the space occupied by the device within the cowl can be reduced.
