  Here, in the present embodiment, a cutout portion 54 (hose insertion portion: temporary fixing portion) capable of temporarily fixing the washer hoses 28 and 30 is formed in the head cover 34 described above. The notch 54 is formed at the base end (the end in the direction of arrow A in each drawing) of the head cover 34 near the upper wall 34U in the front wall 34F. That is, the notch 54 is provided on the side of the arm head 18 on the vehicle front side. The cutout portion 54 is formed by cutting out a part of the front wall portion 34F from the base end side of the head cover 34 toward the front end side in the longitudinal direction, and has a length in the longitudinal direction of the arm head 18. It is formed in a scale shape.

  The dimension L (see FIG. 6) of the notch 54 along the longitudinal direction of the arm head 18 is set to be at least twice the diameter of the washer hoses 28, 30. The notch 54 has a dimension H (see FIG. 6) along the vertical direction of the arm head 18 set to be equal to the diameter of the washer hoses 28, 30. At the lower end of the cutout 54 at the base end of the head cover 34, a projection 56 projecting upward from the arm head 18 is provided. For this reason, the size of the notch 54 along the vertical direction of the arm head 18 at the base end of the head cover 34 is small.

  The notch 54 can be inserted by arranging the two washer hoses 28 and 30 in the radial direction of the pivot shaft 38 (in the direction of a surface substantially perpendicular to the pivot shaft 38, in other words, in the direction substantially parallel to the wiping surface). Have been. When the washer hoses 28 and 30 are inserted into the cutouts 54, the washer hoses 28 and 30 are elastically deformed once in the radial direction of the washer hoses 28 and 30 due to interference with the protruding portion 56. Return. Thus, the two washer hoses 28 and 30 are temporarily fixed (temporarily held) in the cutout portions 54. That is, the washer hoses 28 and 30 inserted into the cutouts 54 interfere with the protruding portions 56 so that the washer hoses 28 and 30 do not come out of the cutouts 54 carelessly. However, when an external force acts on the washer hoses 28, 30 in a direction in which the washer hoses 28, 30 are removed from the notch 54, the washer hoses 28, 30 are removed from the notch 54. Since the direction in which the washer hoses 28, 30 are removed from the notch 54 is in the radial direction of the pivot shaft 38, even if the forehead of removing the washer hoses 28, 30 from the notch 54 is forgotten, the wiper arm 12 can be removed. The dimension H can be adjusted so that it can be removed by a pivoting operation.

  In the temporarily fixed state in which the washer hoses 28 and 30 are inserted into the notches 54 as described above, the base end 32A of the head main body 32 (the head cover 34 in the head main body 32) is viewed from the axial direction of the pivot shaft 38. (The part located on the side of arrow A in FIG. 2), two washer hoses 28 and 30 are temporarily fixed. In this temporarily fixed state, the two washer hoses 28 and 30 do not overlap with the nut 44 and the flat washer 40 when viewed from the axial direction of the pivot shaft 38.

(Action and effect)
Next, the operation and effect of the present embodiment will be described.

  In the vehicle wiper 10 having the above-described configuration, the pivot shaft 38 of the wiper arm 12 is fixedly fastened to a fastening portion 32A1 provided on the base end portion 32A of the arm head 18. The wiper arm 12 is provided with two washer hoses 28, 30. These washer hoses 28 and 30 extend from the arm head 18 along a path passing above the base end portion 32A of the arm head 18. The arm head 18 has an arm as viewed from the axial direction of the pivot shaft 38. A cutout portion 54 is formed at a position where it does not overlap with the base end portion 32A of the head 18 so that the washer hoses 28 and 30 can be temporarily fixed. Since the washer hoses 28, 30 can be temporarily fixed to the cutout portions 54, the washer hoses 28, 30 do not become an obstacle when the base end 32A of the arm head 18 is fastened and fixed to the pivot shaft 38. . This facilitates the fastening operation.

  Further, for example, in the production line of the vehicle wiper 10, the washer hoses 28 and 30 can be temporarily fixed to the cutout portions 54. Accordingly, when the vehicle wiper 10 is delivered to the automobile manufacturing line and fastened and fixed to the pivot shaft 38, the work of temporarily fixing the washer hoses 28 and 30 to the notch portions 54 becomes unnecessary. Therefore, compared to a vehicle wiper having a configuration in which the washer hoses 28 and 30 do not extend from the arm head 18 in a path passing above the base end 32A, the efficiency of the fastening operation to the pivot shaft 38 is made equal. be able to.

  In addition, in the present embodiment, the notch portion 54, which is a temporary fixing portion of the washer hoses 28, 30, is formed in the head cover 34. Therefore, another component is required to temporarily fix the washer hoses 28, 30 to the arm head 18. No need to add. Further, it is not necessary to newly set a process for temporarily fixing the washer hoses 28 and 30 to the wiper arm 12 by using separate components. For this reason, the number of parts and the manufacturing cost can be prevented from increasing.

  Further, in the present embodiment, the arm head 18 has the head body 32 made of aluminum die cast and the head cover 34 made of resin, and the cutout portion 54 is formed in the head cover 34 made of resin. I have. As a result, even if the washer hoses 28 and 30 provided on the wiper arm 12 are flexible and unstable, the washer hoses 28 and 30 are accommodated in the hose accommodating space of the head cover 34 and cover the portion of the arm head 18. While preventing the appearance of the wiper arm 12 from being cluttered, the degree of freedom in the arrangement position of the washer hoses 28 and 30 at the arm head 18 can be improved. Furthermore, for example, the configuration of a die for aluminum die-casting can be simplified as compared with a configuration in which a temporary fixing portion is provided on the head body 32 made of aluminum die-casting, so that the manufacturing cost of the die is reduced. it can.

  In the present embodiment, the base end 32A of the arm head 18 is fastened and fixed to a pivot shaft 38 provided on the lower end side of the front windshield 16. The notch 54 that can temporarily fix the washer hoses 28 and 30 is provided on a front wall portion 34F of the head cover 34, which is a side portion of the arm head 18 on the vehicle front side. Since the front wall portion 34F is covered from the front side of the vehicle by, for example, a hood (not shown) of the vehicle, the notch portion 54 can be made difficult to be visually recognized from the outside of the vehicle.

  Further, in the present embodiment, the washer hoses 28 and 30 are inserted into the notch 54 formed in the head cover 34 in the radial direction of the pivot shaft 38 and temporarily fixed. Thereby, the washer hoses 28 and 30 can be easily temporarily fixed to the cutout portions 54. Moreover, the notch 54 can be inserted by arranging the two washer hoses 28 and 30 in the radial direction of the pivot shaft 38. Thereby, the notch (temporary fixing portion) can be simplified as compared with a configuration in which the two washer hoses 28 and 30 are temporarily fixed to the two notches.

  Further, in the present embodiment, since the simple notch 54 formed in the head cover 34 is a temporary fixing portion of the washer hoses 28 and 30, the temporary fixing portion can have a simple configuration. Further, when the temporary fixing of the washer hoses 28 and 30 is released, the temporary fixing can be easily released since the washer hoses 28 and 30 may be pulled out of the notch portion 54. Therefore, the work of connecting the hose joints 52 of the washer hoses 28 and 30 to the vehicle body after the wiper arm 12 is fastened and fixed to the pivot shaft 38 can be prevented from becoming complicated.

  In the present embodiment, the two washer hoses 28 and 30 are temporarily fixed at positions where the notch portions 54 as temporary fixing portions do not overlap with the base end portion 32A of the arm head 18 when viewed from the axial direction of the pivot shaft 38.
