And the supply path 22 are communicated with each other. The four injection ports 21 face the wiping surface. further,
The supply path 22 is opened in the pipe section 18. One end of a tube or the like 23 for supplying a washer liquid is fitted and fixed to the tube portion 18. The other end of the tube 23 is connected to a washer liquid supply device (not shown).

(Explanation of the operation of the embodiment) The mounting structure of the washer nozzle according to this embodiment has the above-described structure, and the operation thereof will be described below.

First, the mounting portions (main body portion 12 and elastic legs 13, 13) of the washer nozzle member 11 are inserted into the mounting plate portion 6 of the wiper arm 1 in the direction of arrow A. Then, as shown in FIG. 9 (B), the convex piece 9 as the retaining engagement means of the wiper arm 1 and the washer nozzle member 11, and the inclined surfaces 10, 20 of the convex portion 19 slide in contact. At this time, as shown in FIG. 7 (B) and FIG. 9 (B), the elastic deformation portions 14 and 14 of the washer nozzle member 11 are formed.
Is elastically deformed, and the main body 12 opens in the direction of arrow G.

Further, the main body 12 and the elastic legs 13 are inserted into the mounting plate 6 in the direction of arrow A. Then, FIG.
As shown in FIG. 8B and FIG. 8B, the washer nozzle member 1 is provided on the contact surface 7 of the first regulating means of the wiper arm 1.
The contact surface 17 of the first first restricting means contacts. As a result,
By the contact of the contact surfaces 7 and 17 of the first restricting means, the movement in the insertion direction A of inserting the main body 12 and the elastic legs 13 and 13 into the mounting plate 6 is restricted.

When the contact surface 17 of the first restricting means contacts, as shown in FIGS. 6B and 9C,
The elastically deformed elastic deformation portions 14 and 14 elastically return to the original state. For this reason, the main body 12 in the open state is
Is closed, and the engaging surface 190 of the protrusion 19 as the retaining means of the washer nozzle member 11 comes into contact with the engaging surface 90 of the convex piece 9 as the retaining engaging means of the wiper arm 1.
As a result, the washer nozzle member 11 is inserted from the wiper arm 1 in the insertion direction A by the engagement of the engagement surfaces 90 and 190.
In the opposite direction D can be prevented.

Further, when the contact surface 17 of the first regulating means contacts and the engaging surfaces 90 and 190 are engaged, FIG.
As shown in (B), the contact surfaces 15 of the second restricting means of the washer nozzle member 11 contact the contact surface 8 of the second restricting means of the wiper arm 1. As a result, by the contact of the contact surfaces 8, 15, 15 of the second regulating means, the main body 12 and the elastic legs 13, 13 sandwich the main body plate 6, and the main body 12 is attached to the mounting plate 6. 12, elastic legs 13,
The movement in the direction F (the direction perpendicular to) that intersects with the insertion direction A in which the plug 13 is inserted is restricted.

Furthermore, the contact surfaces 7, 1 of the first regulating means
7 comes into contact with each other, and a convex piece 9 as a retaining engagement means,
The engagement surfaces 90 and 190 of the convex portion 19 are engaged, and the second
When the contact surfaces 8, 15, 15 of the restricting means come into contact with each other, as shown in FIG.
2 and the upper surfaces of the elastic legs 13, 13 are in elastic contact. That is, the mounting portion is sandwiched by the mounting plate portion 6. As a result, it is possible to prevent the washer nozzle member 11 from rattling with respect to the wiper arm 1 in the direction E opposite to the pinching direction.

(Explanation of Effect of Embodiment) As described above,
Since the mounting structure of the washer nozzle according to the present embodiment has the above-described configuration, the following effects can be achieved.

That is, the mounting structure of the washer nozzle in this embodiment is the same as the mounting plate 6 of the wiper arm 1.
When assembling the washer nozzle member 11 to the mounting plate 6, the mounting portion (the main body 12 and the elastic legs 13,
When 3) is inserted, a convex piece 9 as a retaining engagement means,
The inclined surfaces 90 and 190 of the convex portion 19 slide and abut, and the elastic deformation portions 14 and 14 of the elastic legs 13 and 13 elastically deform. For this reason, the mounting structure of the washer nozzle in this embodiment is the same as the mounting plate 6 of the wiper arm 1.
The washer nozzle member 11 can be easily assembled.

The washer nozzle mounting structure in this embodiment is such that once the washer nozzle member 11 is mounted on the mounting plate 6 of the wiper arm 1, the main body 1
2 and the elastic legs 13, 13 sandwich the mounting plate 6, the contact surfaces 7, 17 of the first restricting means restrict the movement in the insertion direction A, and the contact surfaces 8, 15, The direction F in which 15 intersects the inserting direction and the inserting direction A, respectively.
And the engagement surfaces 90 and 190 of the convex pieces 9 and the convex portions 19 as the retaining engagement means prevent the detachment in the direction D opposite to the insertion direction A. Thus, in the washer nozzle mounting structure in this embodiment, once assembled, the washer nozzle member 11 is securely mounted on the mounting plate 6 of the wiper arm 1.

In particular, the washer nozzle mounting structure according to the present embodiment is designed such that when the washer nozzle member 11 is mounted on the mounting plate 6 of the wiper arm 1, the washer nozzle members 11 are attached to the outer sides of the elastic legs 13, 13. Is guided by the guide surface 24 of the wiper arm 1. For this reason, the first restricting means, the second restricting means, and the retaining engagement means are guided to a predetermined position and reliably act at the predetermined position. As a result, the washer nozzle mounting structure in this embodiment can securely mount the washer nozzle member 11 to the mounting plate 6 of the wiper arm 1.

[0031]

As is apparent from the above, the mounting structure of the washer nozzle in the wiper arm according to the present invention is such that when the washer nozzle member is mounted on the mounting plate portion of the wiper arm, the mounting portion is inserted into the mounting plate portion. The inclined surface of the retaining engagement means slides and the elastically deforming portion of the sandwiching mounting portion elastically deforms. For this reason, the washer nozzle mounting structure of the wiper arm according to the present invention can easily assemble the washer nozzle member to the mounting plate portion of the wiper arm.

Further, the washer nozzle mounting structure in the wiper arm according to the present invention is such that once the washer nozzle member is assembled on the mounting plate portion of the wiper arm, the sandwiching mounting portion sandwiches the mounting plate portion, and the first regulating means moves in the inserting direction. The movement is regulated, the second regulating means regulates the movement in the direction intersecting the sandwiching direction and the direction intersecting with the inserting direction, respectively, and the retaining means prevents the detachment in the direction opposite to the inserting direction. As a result, the washer nozzle mounting structure in the wiper arm according to the present invention ensures that the washer nozzle member is securely mounted on the mounting plate portion of the wiper arm once assembled.
