It is supported. And the front-end | tip part of the said synchronous link rod 16 is connected with the intermediate part of the longitudinal direction of the main lever 17 via a ball joint so that rolling is possible.

  The sub-lever 18 is plate-like and formed substantially linearly when viewed from the plate thickness direction (axial direction of the second shaft 11c), and its base end portion is rotatably supported on the second support shaft 11c of the holder member 11. Has been. The length of the sub lever 18 is set longer than the length of the main lever 17.

  As shown in FIGS. 1 and 2, the connecting member 19 has a plate-like shape and is linearly formed as seen from the thickness direction (the axial direction of the first connecting portion 31 described later). An upper extending portion 19b extending from the connecting straight portion 19a to the upper side (the top direction side in FIG. 1, the front side of the drawing in FIG. 1) in the plate thickness direction (the axial direction of the first connecting portion 31). An extending piece 19c that is bent and extends at a right angle (in a direction parallel to the connecting straight line portion 19a) from the tip of the installation portion 19b.

  The connecting member 19 is rotatably connected to the first connecting portion 31 at the distal end portion of the main lever 17 at the base end portion of the connecting linear portion 19 a, and the distal end portion of the connecting linear portion 19 a is connected to the sub lever 18.

The length of the connecting straight line portion 19a is set to be substantially the same as the length of the main lever 17.

  Further, the upwardly extending portion 19b of the present embodiment extends from the base end portion of the connecting linear portion 19a to the upper side (the top direction side) in the plate thickness direction (the axial direction of the first connecting portion 31). Note that the upper side (the top direction side) is the side facing the top direction from the horizontal direction, and the plate thickness orthogonal direction (plane direction) of the holder member 11 is inclined with respect to the ground. Therefore, the upper extending portion 19b also extends toward the top side inclined with respect to the ground (see FIG. 4).

Further, the extending piece 19c of the present embodiment is substantially opposite to the extending direction of the connecting straight line portion 19a when viewed from the plate thickness direction (the axial direction of the first connecting portion 31) (leftward in FIGS. 1 and 3). ).
A support shaft 19d that extends upward (top direction) in the plate thickness direction (the axial direction of the first connecting portion 31) is erected at the distal end portion of the extending piece 19c, and is disposed at the distal end portion of the support shaft 19d. The wiper arm 21 is fixed so that the base end of the wiper arm 21 operates integrally with the connecting member 19, and a wiper blade 3 (see FIG. 6) is supported at the tip of the wiper arm 21.

  In the vehicle wiper device (vehicle wiper device) configured as described above, when the motor 14 is driven, the driving force (rotational force of the crank arm 14a) is converted by the drive source side link rod 15 to the pivot lever 22 and The wiper arm 20 and the wiper blade 2 are rotated by being transmitted to the pivot shaft 12d, and the driving force of the drive source side link rod 15 is further transmitted to the main lever 17 by the synchronous link rod 16. When the main lever 17 is rotated, the sub-lever 18 is also rotated in conjunction with it, and the attitude (angle) of the connecting member 19 with respect to the main lever 17 is changed. Accordingly, the wiper arm 21 and the wiper blade are changed. The posture (angle) of 3 also changes integrally with the connecting member 19. In the present embodiment, as shown in FIG. 6, wiping of the wiper blade 3 on the center side (passenger seat side) in the vehicle width direction is performed by such a combined operation of the rotation operation and the apparent expansion / contraction operation. The range Z1 is a desired range that is substantially enlarged (largely bulges to the other end side in the vehicle width direction (the diagonally upper right side in FIG. 6)) although it is substantially fan-shaped. In FIG. 6, the wiping range Z2 when the wiper arm and the wiper blade are simply rotated with one point of the vehicle body in the stopped state of the wiper arm as the axis (rotation center) is also shown as a comparison target.

  Here, as shown in FIG. 3, the movement locus X1 (indicated by a thin line in FIG. 3) of the support shaft 19d in the present embodiment is the movement locus of the base end portion of the extending piece 19c (the base of the connecting straight line portion 19a). 3 is a movement trajectory of the end portion and the upper extension portion 19b, and in FIG. 3, the movement trajectory of the upper extension portion 19b is indicated by a broken line (X2) (the extending direction of the extension piece 19c is not crossed). ) Is set. Then, the posture of the extended piece 19c is rotated while moving, as indicated by the alternate long and short dash line connecting the movement locus X1 of the support shaft 19d and the movement locus X2 of the proximal end portion of the extended piece 19c. By changing the posture (angle) of the extending piece 19c (connecting member 19), the posture (angle) of the wiper arm 21 and the wiper blade 3 is also changed integrally with the connecting member 19, and the front window 1 is wiped off.

  As shown in FIGS. 4 and 5, the cowl louver 41 as a vehicle body cover member provided in the vehicle wiper device mounted on the vehicle has a movement locus X3 (see FIG. 3) of the intermediate portion of the extended piece 19c. Are formed along the vertical direction (top direction) and open in an invisible direction. And the front end side of the extension piece 19c is arrange | positioned through the opening part 41a outside the cowl louver 41 (vehicle body). In addition, the vertical direction upper direction (top direction) said here is a direction which is not inclined, Comprising: It is a gravitational direction.

  Specifically, the cowl louver 41 includes a first cowl member 42 and a second cowl member 43 that are divided at the opening 41a, thereby facilitating assembly to the vehicle body.

  Further, in the present embodiment, the first cowl member 42 that constitutes the lower end side of the opening 41a is erected from the bottom surface 42a, and the lower end position of the opening 41a is vertically above the bottom surface 42a (upward direction). A standing wall 42b is formed (the upper end of which is the lower end of the opening 41a).

  In addition, the lower end position of the opening 41a of the present embodiment is from the visible position Y1 from above the cowl louver 41 in the vertical direction (upward direction) to the vehicle interior side (from the visible position Y1 indicated by a one-dotted line in FIG. 4). Is also shifted to the right invisible range side) with respect to the left visible range.

  In other words, the lower end position of the opening 41a of the present embodiment is located on the vehicle interior side from the upper end position Y2 (indicated by a broken line in FIG. 4) of the opening 41a as viewed from above the cowl louver 41 in the vertical direction (top direction). In FIG. 4, the position is shifted to the right side. Specifically, the second cowl member 43 that constitutes the upper end side of the opening 41a is formed with a lower wall 43a that extends in a direction facing the standing wall 42b (the lower end of which is the upper end of the opening 41a). ing. Although the standing wall 42b and the lower wall 43a extend in the opposite direction, the facing direction is inclined (in a direction substantially orthogonal to the surface of the front window 1), so that the lower end (standing) of the opening 41a is inclined. The position of the upper end of the installation wall 42b is closer to the inner side of the vehicle body (right side in FIG. 4) than the upper end (lower end of the lower installation wall 43a) position Y2 of the opening 41a as viewed from above the cowl louver 41 in the vertical direction. It will be out of position.

  As shown in FIG. 4, the hood hood 51 provided on the vehicle body covers the cowl louver 41 so as to substantially cover the upper part of the cowl louver 41 except for the front window 1 side (that is, the vehicle rear side) that is the operation side of the wiper arm 21. It is spaced apart from the top. Specifically, the hood hood 51 is disposed so as to cover the upper portion of the cowl louver 41 in a range including the opening 41a when viewed from above in the vertical direction (top direction). Note that the front end of the vehicle in the cowl louver 41 is in close contact with the hood hood 51 via a seal member 52.

Next, characteristic effects of the above embodiment will be described below.
(1) The wiping range Z1 is changed to a desired range (substantially enlarged) from a simple fan shape by a composite operation by the four-bar linkage mechanism constituted by the main lever 17, the sub lever 18, and the connecting member 19. Range). The connecting member 19 has a rotation shaft in addition to the connecting linear portion 19a that connects the main lever 17 (first connecting portion 31) and the sub lever 18 (second connecting portion 32) (via the upper extending portion 19b). An extending piece 19c extending substantially in the direction perpendicular to the axis is provided, a support shaft 19d extending upward is provided on the distal end side of the extended piece 19c, and the wiper arm 21 is supported on the distal end side of the support shaft 19d. . Further, the movement locus X1 of the support shaft 19d is set so as not to intersect the movement locus X2 of the proximal end portion of the extending piece 19c. In addition to this configuration, the cowl louver 41 of the vehicle body is formed with an opening 41a that is formed along the movement locus X3 of the intermediate portion of the extending piece 19c and that is open in a direction that is not visible from above (in the vertical direction). In order to dispose the distal end side of the extending piece 19c through the opening 41a outside the cowl louver 41 (vehicle body), for example, it has an opening that is visible from above in the vertical direction (opened upward in the vertical direction). Compared with a thing, it can reduce that dust and liquid (raindrop etc.) permeate into the inside of cowl louver 41 (vehicle body) from opening 41a. Moreover, the external appearance seen from the perpendicular direction upper direction can be improved compared with what has the opening part visually recognizable from the perpendicular direction upper part (opened perpendicularly | vertically upward).

  (2) Since the extending piece 19c is formed from the tip of the upper extending portion 19b extending upward from the connecting straight portion 19a, a step is formed between the connecting straight portion 19a and the extending piece 19c. A sufficient distance from the connecting straight line portion 19a, the main lever 17, the sub lever 18 and the like can be secured, and various designs such as the design of the cowl louver 41 having the opening 41a that does not interfere with them can be facilitated. In other words, when the extending piece 19c is formed on the same plane as the connecting straight line portion 19a, for example, the connecting straight line portion 19a, the main lever 17, the sub lever 18 and the like, and the cowl louver having the opening do not interfere with each other. Although it becomes necessary to secure the arrangement space of the cowl louver by connecting the portion 19a and the main lever 17 with a large step in the axial direction of the first connecting portion 31, these can be avoided.

  (3) The cowl louver 41 (first cowl member 42) is erected from the bottom surface 42a so that the lower end position of the opening 41a is vertically upward (upward) from the bottom surface 42a (the upper end is the lower end of the opening 41a). Since the standing wall 42b is formed, it is further reduced that dust and liquid (raindrops, etc.) enter the inside of the cowl louver 41 (vehicle body) from the opening 41a.

  (4) The lower end position of the opening 41a is visually recognized from the vertically visible position (top direction) Y1 of the cowl louver 41 to the vehicle body inner side (viewed to the left of the visible position Y1 indicated by a one-dot chain line in FIG. 4). The lower end position of the opening 41a is a position that is recessed on the inner side of the vehicle body (right side in FIG. 4) when viewed from above in the vertical direction. Therefore, it is further reduced that dust and liquid (raindrops, etc.) enter the inside of the cowl louver 41 (vehicle body) from the opening 41a.

  (5) The lower end position of the opening 41a is closer to the vehicle interior side than the upper end position Y2 (shown by a broken line in FIG. 4) of the opening 41a as viewed from above the cowl louver 41 in the vertical direction (top direction). For example, even if the liquid (raindrop) reaches the upper end position Y2 of the opening 41a and further falls freely downward, the liquid (raindrop) remains inside the cowl louver 41 (vehicle body). Intrusion to the side is prevented.

  (6) The bonnet hood 51 substantially covers the upper part of the cowl louver 41 except for the front window 1 side (that is, the vehicle rear side) which is the operation side of the wiper arm 21, and has an opening portion as viewed from above in the vertical direction (top direction). Since the upper part of the cowl louver 41 is separated and covered in a range including 41a, the maze structure is bent in a plurality of stages in different directions from the outside of the vehicle body (bonnet hood 51) to the opening 41a of the cowl louver 41. Therefore, it is further reduced that dust and liquid (raindrops etc.) enter the inside of the cowl louver 41 (vehicle body) from the opening 41a.

The above embodiment may be modified as follows.
In the above embodiment, the extending piece 19c is formed by bending from the tip of the upper extending portion 19b extending upward from the connecting straight portion 19a. However, the extending piece 19c extends within the moving range of the connecting straight portion 19a. The movement trajectory (opening) of the intermediate part of the piece is prevented from entering, for example, by opening the connecting linear part 19a and the main lever 17 with a large step in the axial direction of the first connecting part 31. If the arrangement space of the cowl louver having the portion can be secured, the upper extending portion 19b may be omitted (the extended piece is formed on the same plane as the connecting straight portion 19a). Furthermore, although the connecting member 19 is formed by integrally forming the connecting linear portion 19a, the upper extending portion 19b, and the extending piece 19c, the connecting linear portion 19a, the upper extending portion 19b and the extending piece 19c, or The connecting linear portion 19a and the upper extending portion 19b and the extending piece 19c may be separately configured and integrally connected (connected so that the postures of the respective components operate integrally).

  -In above-mentioned embodiment, although the upper extension part 19b extended from the base end part (position of the 1st connection part 31) of the connection linear part 19a to the upper side (top direction side), it is not limited to this. Further, it may extend upward (from the top side) from another position, for example, from the tip of the connecting straight line portion 19a (the position of the second connecting portion 32). Of course, also in this case, it is necessary to set the movement locus of the support shaft (the distal end portion of the extended piece) so as not to intersect with the movement locus of the proximal end portion (the upper extended portion) of the extended piece. The distal end portion (support shaft) of the extended piece is on the axis of the first connecting portion 31 (above the base end portion of the connecting straight portion 19a). Of course, in this case as well, the opening is formed along the movement locus of the intermediate portion of the extended piece.

  In the above-described embodiment, the cowl louver 41 (first cowl member 42) is erected from the bottom surface 42a so that the lower end position of the opening 41a is vertically above the top surface 42a (the top direction).
