  In the vehicle wiper device 10 as described above, the pivot lever 14 is provided with a resin cover member 15 for waterproofing. As shown in FIGS. 1 to 4, the cover member 15 has a surface covering portion 41 that covers the surface 35 of the pivot lever 14. The surface covering portion 41 has a thin plate shape and is in close contact with the surface 35 of the pivot lever 14. Further, the surface covering portion 41 covers the range from the proximal end portion 31 of the pivot lever 14 to about three-fifths of the longitudinal direction.

  The cover member 15 includes a side surface covering portion 42 that extends substantially at right angles from both end portions in the width direction of the surface covering portion 41 (short direction of the pivot lever 14) and covers the side surface in the width direction of the pivot lever 14; A base end covering portion 43 that extends from the base end portion in the longitudinal direction of the portion 41 at a substantially right angle and covers the base end portion 31 of the pivot lever 14 is formed. As shown in FIG. 3, each side surface covering portion 42 is formed with a locking piece 42 a that protrudes inward in the width direction from the inner surface and is locked to the back surface 34 of the pivot lever 14. Accordingly, the cover member 15 is configured to hold the pivot lever 14, and the cover member 15 is prevented from being separated from the pivot lever 14.

  As shown in FIGS. 1, 2, and 4, a plate-like standing wall portion 44 is formed at the distal end portion (the end portion on the ball joint 36 side) of the cover member 15 in the longitudinal direction. The standing wall portion 44 extends at a right angle from the surface covering portion 41 and the side surface covering portion 42. More specifically, the standing wall portion 44 extends from the surface covering portion 41 perpendicularly to the surface 35 of the pivot lever 14 and extends from the side surface covering portions 42 at right angles outward in the width direction. A side wall portion 44b continuously connected to the upper wall portion 44a is provided.

  The surface covering portion 41 is formed with a cylindrical inner peripheral wall portion 45 that surrounds the outer periphery of the pivot shaft 13 and the base end portion 21 c of the rotation support portion 21. The inner peripheral wall portion 45 is parallel to the pivot shaft 13 and the rotation support portion 21, and the central axis line of the inner peripheral wall portion 45 is formed to coincide with the axis line L of the pivot shaft 13. The inner peripheral wall portion 45 is provided inside the covering portion 22 of the pivot holder 12, and the inner peripheral wall portion 45 and the covering portion 22 constitute a maze structure for suppressing water intrusion.

  More specifically, as shown in FIG. 1, the annular wall portion 23 of the covering portion 22 is opposed to the inner peripheral wall portion 45 with a gap in the axis L direction, and an opening 45 a (in the axis L direction) of the inner peripheral wall portion 45. Covers the tip of The outer peripheral wall 24 extending in the axis L direction from the outer edge of the annular wall 23 surrounds the outer periphery of the inner peripheral wall 45, and the lower end (end in the axis L direction) of the outer peripheral wall 24 is It faces the surface covering portion 41 of the cover member 15 with a slight gap. Further, the inner peripheral wall portion 45 and the outer peripheral wall portion 24 form an annular shape centering on the central axis L of the pivot shaft 13, and between the inner peripheral wall portion 45 and the outer peripheral surface 21a of the rotation support portion 21, and A gap in the radial direction is formed between the inner peripheral wall portion 45 and the outer peripheral wall portion 24. In this manner, the movable cover member 15 is configured not to interfere with the fixed cover portion 22. As shown in FIG. 4, the outer diameter of the outer peripheral wall portion 24 is set larger than the width of the surface covering portion 41 (the length in the left-right direction in FIG. 4), and the outer peripheral wall portion 24 in plan view. Is configured to protrude from both sides of the surface covering portion 41 in the width direction.

Next, the operation of this embodiment will be described.
1 and 4, the flow of water that enters the cowl panel 18 from the insertion hole 18a is indicated by a two-dot chain line arrow. The water that enters the cowl panel 18 and adheres to the surface covering portion 41 of the cover member 15 mainly flows toward the pivot shaft 13 due to the inclination of the cover member 15 (pivot lever 14). Then, when the water flowing to the pivot shaft 13 side through the surface covering portion 41 reaches the outer peripheral wall portion 24 of the pivot holder 12, the pivot shaft 13 is avoided along the outer peripheral wall portion 24 as shown in FIG. To the side of the cover member 15 in the width direction. Further, even if a part of the water that has reached the outer peripheral wall portion 24 enters the gap between the outer peripheral wall portion 24 and the surface covering portion 41, an inner peripheral wall portion 45 is provided inside the outer peripheral wall portion 24. Therefore, it is difficult for this water to reach the rotation support portion 21 inside the inner peripheral wall portion 45 against gravity.

  Further, as shown in FIG. 1, when water that has entered the cowl panel 18 adheres to the outer peripheral surface 21a of the rotation support portion 21, the water flows along the outer peripheral surface 21a to the base end portion 21c side and flows into the annular wall. The unit 23 is reached. That is, since the inner peripheral wall portion 45 of the cover member 15 is covered in the axis L direction by the covering portion 22 (the annular wall portion 23 and the outer peripheral wall portion 24), the water flowing along the outer peripheral surface 21a of the rotation support portion 21. Is prevented from entering the inside of the inner peripheral wall portion 45.

  Thus, since the periphery of the base end portion 21c of the rotation support portion 21 is surrounded by the maze structure formed by the covering portion 22 and the inner peripheral wall portion 45, the water that has entered the cowl panel 18 rotates. It is difficult to reach the base end portion 21 c of the support portion 21. Thus, it is possible to prevent water from entering from the base end portion 21 c of the rotation support portion 21 between the rotation support portion 21 and the pivot shaft 13, and as a result, a lubricant (grease or the like) filled therebetween. ) And rusting of the pivot shaft 13 are suppressed.

  In addition, since the front-end | tip part 21b of the rotation support part 21 is covered with the extension part 17a of the wiper arm 17 base end, it is difficult for water to adhere to this front-end | tip part 21b vicinity. Thereby, it is suppressed that water permeates between the rotation support part 21 and the pivot shaft 13 from the tip part 21b.

  In addition, there is a case where water that has entered the insertion hole 18a and dropped freely, or water that has entered the cowl panel 18 and has hit the surface covering portion 41 of the cover member 15 and scattered to the ball joint 36 side. Since the water is blocked by the standing wall portion 44, the adhesion of water to the vicinity of the ball joint 36 is suppressed.

Next, characteristic effects of the present embodiment will be described.
(1) The pivot support portion 21 of the pivot holder 12 pivotally supports the pivot shaft 13 on the tip end portion 13b side of the pivot shaft 13 from the fixed position of the pivot lever 14, and a cover member attached to the pivot lever 14 15 is provided with a cylindrical inner peripheral wall portion 45 that surrounds the outer periphery of the pivot shaft 13 and the base end portion 21 c of the rotation support portion 21. The pivot holder 12 includes an annular wall portion 23 that extends from the outer peripheral surface 21 a of the rotation support portion 21 and covers the opening of the inner peripheral wall portion 45, and an annular wall portion 23 that surrounds the outer periphery of the inner peripheral wall portion 45. An extended outer peripheral wall portion 24 is provided. For this reason, the water flowing toward the pivot shaft 13 through the surface covering portion 41 is blocked by the inner peripheral wall portion 45 and the outer peripheral wall portion 24 that surround the base end portion 21 c of the rotation support portion 21. Further, water that enters through the insertion hole 18 a and flows to the base end portion 21 c through the outer peripheral surface 21 a of the rotation support portion 21 is blocked by the covering portion 22 (the annular wall portion 23 and the outer peripheral wall portion 24) of the pivot holder 12. . Thereby, it is possible to prevent water from entering between the base end portion 21 c of the rotation support portion 21 and the pivot shaft 13.

  (2) In the pivot lever 14, the input portion (ball joint 36) to which the driving force of the motor M is input is positioned above the fixing portion (through hole 33) between the pivot shaft 13 and the pivot lever 14 in the vertical direction. Configured as follows. As a result, water attached to the cover member 15 attached to the pivot lever 14 easily flows toward the pivot shaft 13 due to gravity, so that the waterproof structure composed of the inner peripheral wall portion 45, the annular wall portion 23 and the outer peripheral wall portion 24 is effective. Becomes more prominent, and water flowing toward the ball joint 36 can be reduced.

  (3) The rotation transmitting unit is composed of a metal pivot lever 14 that is fixed to the pivot shaft 13 and receives the driving force of the motor M, and a resin cover member 15 that partially covers the pivot lever 14. The inner peripheral wall 45 is formed on the cover member 15. Thereby, adhesion of water to the pivot lever 14 can be suppressed, and as a result, rusting of the pivot lever 14 can be suppressed. Moreover, since the inner peripheral wall part 45 is formed in the resin cover member 15, the inner peripheral wall part 45 can be easily formed.

  (4) On the end surface (surface covering portion 41) on the pivot holder 12 side of the cover member 15, a standing wall portion 44 that is positioned between the through hole 33 and the ball joint 36 is erected. As a result, for example, water that has fallen freely from the insertion hole 18a or water that has splashed against the cover member 15 is blocked by the standing wall 44, so that water connected to the ball joint 36 and the pivot lever 14 or to the ball joint 36 is blocked. Can be suppressed.

In addition, you may change embodiment of this invention as follows.
In the above embodiment, the cover member 15 is configured to be held with respect to the pivot lever 14 by the locking piece 42a of the side surface covering portion 42. In addition to this, for example, the cover member 15 is formed to protrude on the back surface of the surface covering portion 41.
