[Figure 13] This is a perspective view showing the degree of distortion in the wiring mounting area for RHD. [Modes for carrying out the invention]

[0009] Embodiments of the present invention will be described in detail below with reference to the drawings.

[0010] <Embodiment 1> Figure 1 is a perspective view showing a wiper device for LHD (Embodiment 1). Figure 2 is an enlarged perspective view of the AS side of Figure 1. Figure 3 is a perspective view showing the AS side holder member of Figure 2 by itself. Figure 4 is a perspective view of the AS side waterproof cover of Figure 2 seen from the back. Figure 5 is a view from arrow A in Figure 2 showing the degree of distortion of the wiring mounting section for LHD. Figure 6 is a view from arrow B in Figure 2 (viewed from below) showing the degree of distortion of the wiring mounting section for LHD. Figure 7 is a perspective view showing the degree of distortion of the wiring mounting section for LHD.

[0011] <Wiper device> The wiper device 10 shown in Figure 1 is installed on a vehicle with the steering wheel on the left side in the direction of travel, and is a wiper device for LHD (left-hand drive) vehicles. The wiper device 10 is positioned at the front of the vehicle and near the front windshield, and wipes away rainwater, dust, etc. that adheres to the front windshield. Specifically, the wiper device 10 is equipped with a DR-side (driver's side) wiper member 11 and an AS-side (passenger's side) wiper member 12, and is driven by operating a wiper switch located inside the vehicle. As a result, the DR-side wiper member 11 and the AS-side wiper member 12 perform a back-and-forth wiping operation on the front windshield.

[0012] The AS-side wiper member 12 corresponds to the wiper member in the present invention.

[0013] Here, since the wiper device 10 is for an LHD vehicle, as shown in FIG. 1, in the arrangement direction of the DR side wiper shaft 25 and the AS side wiper shaft 34, the side where the DR side wiper shaft 25 is arranged is defined as the "left side", and the side where the AS side wiper shaft 34 is arranged is defined as the "right side". Also, in the axial direction of the DR side wiper shaft 25 and the AS side wiper shaft 34, the tip side where the DR side wiper member 11 and the AS side wiper member 12 are attached is defined as the "upper side", and the base end side where the link member 17 is provided is defined as the "lower side". Further, the direction orthogonal to both the above-described left-right direction and up-down direction, and the side where the engine room is arranged is defined as the "front side", and the side where the passenger compartment is arranged is defined as the "rear side".

[0014] <Wiper motor> As shown in FIG. 1, the wiper device 10 includes a wiper motor 13 as a drive source. Specifically, the wiper motor 13 has a motor unit 14 and a gear unit 15. Here, for the motor unit 14, for example, a brushed electric motor or a brushless electric motor is adopted. Also, the gear unit 15 is composed of, for example, a worm reducer and is driven by the motor unit 14. And the gear unit 15 has an output shaft 16, and a high-torque rotational force is output from the output shaft 16 toward the link member 17.

[0015] Here, the wiper motor 13 is fixed to a frame member 24 extending in the longitudinal direction (left-right direction) of the wiper device 10.

[0016] <Link member> Also, the wiper device 10 includes a link member 17 that converts the rotational motion of the output shaft 16 into a rocking motion. The link member 17 is provided between the output shaft 16 and the base end portions of the DR side wiper shaft 25 and the AS side wiper shaft 34 so as to be able to transmit power. That is, the link member 17 has a function of transmitting the driving force of the output shaft 16 to the DR side and AS side wiper shafts 25 and 34. Here, the link member 17 is formed by a crank arm 18, a drive rod 19, a DR side drive lever 20, an AS side drive lever 21, and a connecting rod 22.

[0017] The AS-side wiper shaft 34 corresponds to the wiper shaft in this invention.

[0018] Specifically, one end of the crank arm 18 is fixed to the output shaft 16. The other end of the crank arm 18 is connected to one end of the drive rod 19 via a ball joint. Furthermore, one end of the DR-side drive lever 20 is fixed to the base end of the DR-side wiper shaft 25, and the other end of the DR-side drive lever 20 is connected to the other end of the drive rod 19 via a ball joint. Also, one end of the AS-side drive lever 21 is fixed to the base end of the AS-side wiper shaft 34, and the other end of the AS-side drive lever 21 is connected to one end of the connecting rod 22 via a ball joint. Furthermore, the other end of the connecting rod 22 is connected to the other end of the DR-side drive lever 20 via a ball joint.

[0019] As a result, the wiper motor 13 is driven to rotate the output shaft 16 in one direction, causing the DR-side wiper shaft 25 and the AS-side wiper shaft 34 to oscillate synchronously.

[0020] <Holder component> As shown in Figure 1, the wiper device 10 is provided with a rod-shaped, aluminum DR-side holder member 23 and an AS-side holder member 30 on the left and right sides along its longitudinal direction. Specifically, since the wiper device 10 is for LHD (left-hand drive) vehicles, the DR-side holder member 23 is located on the left side of the wiper device 10, and the AS-side holder member 30 is located on the right side. The DR-side and AS-side holder members 23 and 30 are integrated with each other by a frame member 24 made of a hollow pipe. In other words, the wiper device 10 is a frame-integrated modular wiper device.

[0021] The AS-side holder member 30 corresponds to the holder member in the present invention.

[0022] Here, the DR-side and AS-side holder members 23 and 30 have substantially the same structure, and it is the AS-side that possesses the features according to the present invention. Therefore, the description of the DR-side holder member 23 will be omitted below, and only the structure of the AS-side holder member 30 will be described in detail.

[0023] As shown in Figure 1, the DR-side holder member 23 rotatably supports the DR-side wiper shaft 25, to which the DR-side wiper member 11 is attached at its tip (upper side). The DR-side holder member 23 is also fitted with a resin DR-side waterproof cover 26, which prevents the base end (lower side) of the DR-side wiper shaft 25 from being exposed to water.

[0024] As shown in Figure 3, the AS-side holder member 30 rotatably supports the AS-side wiper shaft 34, to which the AS-side wiper member 12 is attached at its tip (upper side). The AS-side holder member 30 includes a holder body 31 that extends in the left-right direction. A cylindrical support portion 32 is provided approximately in the center of the holder body 31 along its longitudinal direction, and slightly to the left. A radial bearing 33 is mounted radially inside the support portion 32, and this radial bearing 33 rotatably supports the AS-side wiper shaft 34. In other words, the support portion 32 of the AS-side holder member 30 rotatably supports the AS-side wiper shaft 34 via the radial bearing 33.

[0025] Furthermore, a positioning projection 32a for positioning the AS-side waterproof cover 40 is provided on the outer circumference and front side of the support portion 32. The positioning projection 32a protrudes radially outward from the support portion 32 to a predetermined height and fits into a positioning recess 45a (see Figure 4) provided on the fixing portion 45 of the AS-side waterproof cover 40. As a result, the AS-side waterproof cover 40 is firmly fixed to the support portion 32 so that it cannot rotate relative to it.

[0026] Furthermore, a vehicle body fixing portion 35 is provided on the right side of the holder body 31 along its longitudinal direction for fixing the AS side of the wiper device 10 to the vehicle body. A rubber bushing 36 is attached to the vehicle body fixing portion 35, thereby elastically supporting the AS side of the wiper device 10 against the vehicle body. As a result, vibrations from the operation of the wiper device 10 are less likely to be transmitted to the vehicle body, ensuring quietness inside the vehicle. In addition, vibrations from the vehicle body are less likely to be transmitted to the wiper device 10, preventing damage to the wiper device 10 due to vibrations. The DR side holder member 23 is also fitted with the same bushing 36 as the AS side (see Figure 1).

[0027] Furthermore, a frame fixing portion 37 is provided on the left side of the holder body 31 along its longitudinal direction, to which the end of the frame member 24 is fixed. Multiple crimping recesses 37a are provided on the outer circumference of the frame fixing portion 37, and by attaching the frame member 24 to the frame fixing portion 37 and crimping the portion of the frame member 24 corresponding to the crimping recesses 37a from the outside, the end of the frame member 24 is firmly fixed to the frame fixing portion 37. In other words, the frame member 24 is crimped and fixed to the AS side holder member 30.

[0028] Furthermore, in the longitudinal direction of the holder body 31, a holder-side abutment portion 38 is provided between the support portion 32 and the frame fixing portion 37. The holder-side abutment portion 38 has the function of preventing the AS-side waterproof cover 40 from being significantly distorted when the wiring LN (see Figure 2) is attached to the LHD wiring mounting portion 48 (see Figure 4) of the AS-side waterproof cover 40. The first cover-side abutment portion 46a and the second cover-side abutment portion 46b (see Figure 4) of the AS-side waterproof cover 40 can abut against the holder-side abutment portion 38 from its left side.

[0029] Specifically, the holder-side abutment portion 38 is arranged to surround the outer circumference of the holder body 31 in a roughly U-shape and protrudes to a predetermined height in front of, behind, and above the holder body 31. The abutting action of the first cover-side abutment portion 46a and the second cover-side abutment portion 46b against the holder-side abutment portion 38 will be described in detail later.

[0030] <Waterproof cover on the AS side> As shown in FIGS. 2 and 4, the waterproof cover 40 on the AS side prevents the base end portion of the AS side wiper shaft 34 from being wetted, and is formed in a substantially plate shape from a resin material such as plastic.

[0031] Note that the waterproof cover 40 on the AS side corresponds to the waterproof cover in the present invention.

[0032] The waterproof cover 40 on the AS side includes an umbrella portion 41 that extends in the front-rear direction and the left-right direction and is formed in a substantially square shape. The umbrella portion 41 has a front surface SF1 and a back surface SF2, and water droplets transmitted through the front windshield are dripped onto the front surface SF1 of the umbrella portion 41. That is, the umbrella portion 41 has a function of receiving water droplets.

[0033] Also, on the outer peripheral portion of the umbrella portion 41, and at three locations on the left and right sides and the rear side thereof, side wall portions 42 are integrally provided. Specifically, the side wall portions 42 are formed in a substantially U shape when viewed from above, and protrude upward from the front surface SF1 of the umbrella portion 41 at a predetermined height. Thereby, the water droplets dripped onto the front surface SF1 of the umbrella portion 41 do not leak out to the outside from the left and right sides and the rear side of the umbrella portion 41. And, there is no side wall portion 42 on the front side of the umbrella portion 41 and an opening portion 43 is provided. Thereby, the water droplets dripped onto the front surface SF1 of the umbrella portion 41 are discharged to the outside of the umbrella portion 41 from the opening portion 43. Note that the water droplets discharged from the waterproof cover 40 on the AS side do not reach the base end portion of the AS side wiper shaft 34 or the link member 17.

[0034] Here, a plurality of convex portions 44 are provided on the front surface SF1 of the umbrella portion 41 and near the opening portion 43. These convex portions 44 are arranged in the left-right direction with a predetermined gap therebetween, and while allowing the discharge of water droplets dripped onto the front surface SF1 of the umbrella portion 41, they have a function of capturing relatively large dust such as dead leaves. Thereby, it is possible to prevent dust from accumulating on a part of the engine or the like. Note that depending on the specifications of the vehicle (such as the arrangement of the engine), the plurality of convex portions 44 can also be omitted.

[0035] Furthermore, a fixing portion 45 is provided on the surface SF1 of the umbrella portion 41, approximately in the center, which is fixed to the support portion 32 (see Figure 3) of the AS-side holder member 30. The fixing portion 45 is formed in a cylindrical shape and is attached to the support portion 32 so as to cover its outer circumference. Here, the fixing portion 45 is prevented from coming off the support portion 32 via a retaining ring SR fixed to the AS-side wiper shaft 34. In other words, the retaining ring SR fixed to the AS-side wiper shaft 34 prevents the AS-side waterproof cover 40 from moving relative to the AS-side holder member 30 in the axial direction (up and down direction) of the AS-side wiper shaft 34.

[0036] Furthermore, as shown in Figure 4, a positioning recess 45a is provided on the radially inner side and axially lower side of the fixing portion 45. The positioning recess 45a is located in front of the fixing portion 45 and is recessed radially outward from the fixing portion 45. The positioning projection 32a of the support portion 32 (see Figure 3) fits into the positioning recess 45a. As a result, the AS-side waterproof cover 40 and the AS-side holder member 30 do not rattle with each other and cannot rotate relative to each other.

[0037] As shown in Figure 4, the underside SF2 of the umbrella portion 41 is provided with a first reinforcing rib RB1, a second reinforcing rib RB2, and a third reinforcing rib RB3 that extend in the front-to-back direction and are aligned in the left-to-right direction. These first, second, and third reinforcing ribs RB1, RB2, and RB3 protrude downward at a predetermined height, intersecting the direction in which the umbrella portion 41 expands, and have the function of reinforcing the umbrella portion 41 of the AS side waterproof cover 40 and increasing its strength.

[0038] The first reinforcing rib RB1 is positioned on the left side of the umbrella section 41, the third reinforcing rib RB3 is positioned on the right side of the umbrella section 41, and the second reinforcing rib RB2 is positioned between the first reinforcing rib RB1 and the third reinforcing rib RB3. Since a fixing section 45 is provided approximately in the center of the umbrella section 41, the second reinforcing rib RB2 is shorter than the first and third reinforcing ribs RB1 and RB3.

[0039] Furthermore, the underside SF2 of the umbrella portion 41 is provided with a fourth reinforcing rib RB4, a fifth reinforcing rib RB5, and a sixth reinforcing rib RB6 that extend in the left-right direction and are aligned in the front-back direction. These fourth, fifth, and sixth reinforcing ribs RB4, RB5, and RB6 also serve to reinforce the umbrella portion 41 of the AS side waterproof cover 40, thereby increasing its strength. In addition, the fourth, fifth, and sixth reinforcing ribs RB4, RB5, and RB6 also protrude downward from the underside SF2 of the umbrella portion 41 to a predetermined height.

[0040] The fourth reinforcing rib RB4 is positioned on the front side of the umbrella section 41, the sixth reinforcing rib RB6 is positioned on the rear side of the umbrella section 41, and the fifth reinforcing rib RB5 is positioned between the fourth reinforcing rib RB4 and the sixth reinforcing rib RB6. The fifth reinforcing rib RB5 is positioned closer to the fourth reinforcing rib RB4 in order to avoid the fixing portion 45 of the umbrella section 41.

[0041] Furthermore, the first reinforcing rib RB1 and the third reinforcing rib RB3, which extend in the front-rear direction, are provided with a first notch 46 and a second notch 47, respectively. These first and second notches 46 and 47 are recessed into the upper side of the AS-side waterproof cover 40 and are positioned on both sides of the fixing portion 45 in the left-right direction of the AS-side waterproof cover 40. The holder body 31 (see Figure 3) of the AS-side holder member 30 is inserted inside the first notch 46 and the second notch 47 in a non-contact manner, crossing them. In other words, the AS-side holder member 30 and the first and third reinforcing ribs RB1 and RB3 are arranged to intersect each other.

[0042] A first cover-side abutment portion 46a and a second cover-side abutment portion 46b are provided at the lower corners of the first notch 46 provided in the first reinforcing rib RB1, that is, at the opening side corners of the first notch 46. Specifically, as shown in Figure 6, the first cover-side abutment portion 46a is located on the front side of the AS-side holder member 30, and the second cover-side abutment portion 46b is located on the rear side of the AS-side holder member 30.

[0043] In other words, the first reinforcing rib RB1 extends in a direction (front-to-back direction) that intersects both the extending direction (up and down direction) of the AS-side wiper shaft 34 and the extending direction (left and right direction) of the AS-side holder member 30, and the second cover-side abutment portion 46b is provided on the side opposite to the side on which the first cover-side abutment portion 46a of the first reinforcing rib RB1 is provided, with the AS-side holder member 30 as the center. Thus, the first reinforcing rib RB1 is provided with first and second cover-side abutment portions 46a and 46b, respectively.

[0044] In the wiper device 10 for LHD, the first cover-side abutment portion 46a corresponds to the cover-side abutment portion in the present invention, and the second cover-side abutment portion 46b corresponds to the auxiliary cover-side abutment portion in the present invention. Also, in the wiper device 10 for LHD, the first reinforcing rib RB1 corresponds to the reinforcing rib in the present invention.

[0045] As shown in Figure 6, when the AS-side waterproof cover 40 is attached to the AS-side holder member 30, the first and second cover-side abutment portions 46a and 46b are positioned to the left of the holder-side abutment portion 38 in the left-right direction of the AS-side holder member 30. Furthermore, the first and second cover-side abutment portions 46a and 46b can abut against the holder-side abutment portion 38 with a small gap in between.

[0046] Specifically, the first cover-side abutment portion 46a is positioned between the fixing portion 45 and the LHD wiring mounting portion 48, and is the point that abuts against the holder-side abutment portion 38 provided on the AS-side holder member 30 when the wiring LN is attached to the LHD wiring mounting portion 48. As a result, as shown in Figures 5 to 7, when the wiring LN is attached to the LHD wiring mounting portion 48 of the AS-side waterproof cover 40, excessive distortion of the AS-side waterproof cover 40 is suppressed.

[0047] As shown in Figures 2 and 4, a wiring mounting section 48 for the left HD is provided on the front and left side of the umbrella portion 41. Wiring LN, which supplies drive current to the motor portion 14 of the wiper motor 13, is mounted on the wiring mounting section 48 for the left HD. Specifically, the wiring mounting section 48 for the left HD is formed in a substantially box shape and protrudes to a predetermined height from the left side of the umbrella portion 41. Furthermore, the wiring mounting section 48 for the left HD is positioned on the extensions of the fourth reinforcing rib RB4 and the fifth reinforcing rib RB5 in the left-right direction of the AS side waterproof cover 40.

[0048] Furthermore, as shown in Figure 5, the tip (left side) of the LHD wiring mounting section 48 protrudes toward the underside of the AS side waterproof cover 40. Also, as shown in Figure 6, the tip (left side) of the LHD wiring mounting section 48 protrudes toward the rearside of the AS side waterproof cover 40.

[0049] In the left-right direction of the AS-side waterproof cover 40, a pressing surface 48a is provided on the left side of the LHD wiring mounting section 48, against which a clip member 50 supporting the wiring LN is pressed. The pressing surface 48a extends in the front-rear and up-down directions of the AS-side waterproof cover 40 and is a surface that intersects with the left-right direction of the AS-side waterproof cover 40. As shown in Figure 6, a positioning recess 45a, which is part of the fixing section 45, and a first cover-side abutment section 46a are arranged within the projection range AR of the pressing surface 48a along the left-right direction of the AS-side waterproof cover 40, that is, along the pressing direction of the clip member 50.

[0050] Furthermore, as shown in Figure 4, the tip side (left side) of the wiring mounting section 48 for LHD is provided with a clip fixing hole 48b into which the engaging claw portion 52 of the clip member 50 is inserted and fixed. The clip fixing hole 48b is formed in a substantially elliptical shape and penetrates the AS side waterproof cover 40 in the left-right direction. As a result, by pressing the clip member 50 against the pressing surface 48a, the engaging claw portion 52 of the clip member 50 (see Figures 5 to 7) is inserted into the clip fixing hole 48b and fixed. Here, the fixing structure between the engaging claw portion 52 and the clip fixing hole 48b employs a so-called snap-fit ​​fixing structure.

[0051] Here, as shown in Figure 4, the lower corners of the second notch 47 provided in the third reinforcing rib RB3, that is, the pair of corners on the opening side of the second notch 47, are provided with a third cover-side abutment portion 47a and a fourth cover-side abutment portion 47b. Specifically, the third cover-side abutment portion 47a is located on the front side of the AS-side holder member 30, and the fourth cover-side abutment portion 47b is located on the rear side of the AS-side holder member 30 (see Figure 12).

[0052] In other words, the third reinforcing rib RB3 extends in a direction (front-to-back direction) that intersects both the extending direction (up and down direction) of the AS-side wiper shaft 34 and the extending direction (left and right direction) of the AS-side holder member 30, and the fourth cover-side abutment portion 47b is provided on the side opposite to the side on which the third cover-side abutment portion 47a of the third reinforcing rib RB3 is provided, with the AS-side holder member 30 as the center. Thus, the third reinforcing rib RB3 is provided with the third and fourth cover-side abutment portions 47a and 47b, respectively.

[0053] Furthermore, these third cover-side abutment portions 47a and fourth cover-side abutment portions 47b perform abutment function in the RHD (right-hand drive) wiper device 60 (see Figure 8), which will be described later, in the same way as the first and second cover-side abutment portions 46a and 46b described above. In other words, the third and fourth cover-side abutment portions 47a and 47b do not perform abutment function in the LHD wiper device 10.

[0054] Furthermore, a wiring mounting section 49 for RHD is provided on the right side of the umbrella section 41, approximately in the center along the front-rear direction. The wiring mounting section 49 for RHD is the part where the wiring LN is mounted in the RHD wiper device 60 (see Figure 8), while the wiring LN is not mounted in the LHD wiper device 10. That is, in the LHD wiper device 10, the LHD wiring mounting section 48 and the first and second cover-side abutment sections 46a and 46b are the parts that function in relation to the wiring LN, while in the RHD wiper device 60, the wiring mounting section 49 for RHD and the third and fourth cover-side abutment sections 47a and 47b are the parts that function in relation to the wiring LN.

[0055] In other words, the AS-side waterproof cover 40 is a common part applicable to both the wiper device 10 for LHD and the wiper device 60 for RHD. Therefore, parts management can be easily performed at the wiper device assembly site, which in turn can improve the efficiency of wiper device assembly.

[0056] Furthermore, the RHD wiring mounting section 49 is formed in a roughly box shape, similar to the LHD wiring mounting section 48. The RHD wiring mounting section 49 protrudes to a predetermined height on the right side of the umbrella section 41. Specifically, the RHD wiring mounting section 49 is positioned on the extensions of the fifth reinforcing rib RB5 and the sixth reinforcing rib RB6 in the left-right direction of the AS-side waterproof cover 40. In addition, the tip (right side) of the RHD wiring mounting section 49 protrudes toward the front of the AS-side waterproof cover 40.

[0057] Furthermore, in the left-right direction of the AS-side waterproof cover 40, a pressing surface 49a (see Figure 2) is provided on the right side of the RHD wiring mounting section 49, against which a clip member 50 supporting the wiring LN is pressed. The pressing surface 49a extends in the front-rear and left-right directions of the AS-side waterproof cover 40 and is a surface that intersects with the vertical direction of the AS-side waterproof cover 40.

[0058] Furthermore, as shown in Figures 2 and 4, the tip side (right side) of the RHD wiring mounting section 49 is provided with a clip fixing hole 49b into which the engaging claw portion 52 of the clip member 50 is inserted and fixed. The clip fixing hole 49b is formed in a substantially elliptical shape and penetrates the AS side waterproof cover 40 in the vertical direction. As a result, by pressing the clip member 50 against the pressing surface 49a, the engaging claw portion 52 of the clip member 50 can be inserted into the clip fixing hole 49b and fixed. Here, the fixing structure between the engaging claw portion 52 and the clip fixing hole 49b is also a snap-fit ​​fixing structure.

[0059] As shown in Figure 6, in the wiring mounting section 48 for LHD, the pressing surface 48a, the positioning recess 45a, and the first cover side abutment 46a are arranged to overlap with each other in the direction in which the clip member 50 is pressed. In contrast, in the wiring mounting section 49 for RHD, the pressing surface 49a does not overlap with anything in the direction in which the clip member 50 is pressed (see Figure 13). In other words, the degree of distortion of the AS side waterproof cover 40 in the direction in which the clip member 50 is pressed is different for the wiper device 10 for LHD and the wiper device 60 for RHD.

[0060] In the wiper device 10 for LHD, the LHD wiring mounting section 48 corresponds to the wiring mounting section in the present invention, and in the wiper device 60 for RHD, the RHD wiring mounting section 49 corresponds to the wiring mounting section in the present invention.

[0061] <Wiring> As shown in Figure 1, the wiring LN supplies drive current to the wiper motor 13. A connector connector CN is provided on one longitudinal side of the wiring LN, which is fixed to the wiring connection part LC of the wiper motor 13. The other longitudinal side of the wiring LN is electrically connected to an on-board controller located on the vehicle side. As a result, by operating the wiper switch located inside the vehicle, drive current is supplied from the on-board controller to the wiper motor 13, and the wiper device 10 is activated.

[0062] In this case, the wiring LN may be too long and become loose depending on the specifications of the vehicle on which the wiper device 10 is installed. When the wiring LN becomes loose, it shakes violently due to vehicle vibrations, which can lead to problems such as the wiring LN breaking. Therefore, in the wiper device 10 of this embodiment, in order to eliminate the looseness of the wiring LN, a clip member 50 is provided at the location where the wiring LN becomes loose, and the clip member 50 is attached to the LHD wiring mounting section 48 of the AS side waterproof cover 40.

[0063] The clip member 50 comprises a band portion 51 that supports the wiring LN, and an engaging claw portion 52 that is integrally provided with the band portion 51 and is inserted into and fixed in the clip fixing hole 48b (see Figure 4) of the LHD wiring mounting portion 48. Here, the engaging claw portion 52 is elastically deformable by the application of external force and can be hooked into the clip fixing hole 48b.

[0064] <Assembly Instructions> Next, the assembly procedure for the LHD wiper device 10 formed as described above will be explained in detail with reference to Figures 5 to 7. In particular, the procedure for attaching the wiring LN to the LHD wiring mounting section 48 will be explained in detail. Note that, for the sake of explanation, only the wiring LN having the AS side holder member 30, the AS side waterproof cover 40, and the clip member 50 is shown in Figures 5 to 7.

[0065] First, prepare the wiring LN with the clip member 50 attached, and also prepare the pre-assembled wiper device 10 for LHD. The installation of the wiring LN to the wiper device 10 is performed, for example, by a vehicle manufacturer that assembles vehicles. However, the automotive parts manufacturer that manufactures the wiper device may also pre-install the wiring LN to the wiper device 10.

[0066] As shown by the solid arrows in Figures 5 to 7, the clip member 50 supporting the wiring LN is pressed against the pressing surface 48a of the LHD wiring mounting section 48 with a pressing force F1. At this time, the clip member 50 is positioned facing the LHD wiring mounting section 48 from the left side of the AS-side waterproof cover 40, and the engaging claw portion 52 of the clip member 50 is inserted straight into the clip fixing hole 48b of the LHD wiring mounting section 48.

[0067] As a result of the pressing force F1, the LHD wiring mounting portion 48 tends to deform clockwise around the base of the LHD wiring mounting portion 48, as shown by the dashed arrow M1 in Figures 5 and 7. At this time, as shown in Figure 6, the positioning recess 45a and the first cover side abutment portion 46a are positioned within the projection range AR of the pressing surface 48a in the direction in which the pressing force F1 of the clip member 50 acts.

[0068] Therefore, the pressing force F1 is first transmitted to the fixed part 45, which is fixed around the axis CT of the support part 32. Thus, in the vicinity of the first part SP1, the fixed part 45 is strongly pressed against the support part 32. At this time, as shown in Figure 5, the extending direction (vertical direction) of the support part 32 (AS side wiper shaft 34) and the pressing direction (rightward direction) of the clip member 50 are perpendicular to each other. Therefore, the pressing force F1 is transmitted directly to the side of the support part 32 and does not act in the direction (upward direction) that would detach the AS side waterproof cover 40 from the AS side holder member 30. Thus, the AS side waterproof cover 40 does not detach from the AS side holder member 30.

[0069] Subsequently, the pressing force F1 acts to distort the AS-side waterproof cover 40, and as a result, the minute gap between the first cover-side abutment portion 46a and the holder-side abutment portion 38 is closed (see Figure 6). Therefore, at the location of the second portion SP2, the first cover-side abutment portion 46a abuts against the holder-side abutment portion 38, as shown by the dashed arrow P1 in Figure 7. Thus, further distortion of the AS-side waterproof cover 40 near the base portion of the LHD wiring mounting portion 48 is suppressed. This makes it possible to easily insert the engaging claw portion 52 of the clip member 50 into the clip fixing hole 48b of the LHD wiring mounting portion 48.

[0070] In this way, in the direction in which the pressing force F1 acts, the holder-side abutment portion 38 supports (holds firm) the AS-side waterproof cover 40 at the location of the second portion SP2 positioned between the first portion SP1 and the pressing surface 48a, preventing it from being distorted further. Therefore, excessive distortion of the AS-side waterproof cover 40 is suppressed, which in turn improves the assembly workability of the wiper device 10.

[0071] Furthermore, the pressing state of the clip member 50 against the pressing surface 48a can be easily confirmed from above, below, and in front of the wiper device 10. Therefore, the operator can easily grasp the degree to which the engaging claw portion 52 is engaged with the clip fixing hole 48b (attachment state).

[0072] Here, for example, if the pressing force F1 becomes too large and the AS-side waterproof cover 40 deforms more significantly, the deformation of the first cover-side abutment portion 46a will increase, and the support capacity of the first cover-side abutment portion 46a alone will be insufficient. In this case, the second cover-side abutment portion 46b will abut against the holder-side abutment portion 38 as an auxiliary abutment. Therefore, even if the pressing force F1 becomes larger than expected, the components such as the AS-side waterproof cover 40 will not be damaged, and the assembly workability of the wiper device 10 will not be reduced.

[0073] As described in detail above, according to the wiper device 10 of Embodiment 1, the AS-side waterproof cover 40 has a fixing part 45 fixed to the support part 32, an LHD wiring mounting part 48 on which the wiring LN that supplies drive current to the wiper motor 13 is attached, and a first cover-side abutment part 46a which is positioned between the fixing part 45 and the LHD wiring mounting part 48 and abuts against a holder-side abutment part 38 provided on the AS-side holder member 30 when the wiring LN is attached to the LHD wiring mounting part 48.

[0074] As a result, when attaching the wiring LN to the wiring mounting section 48 for the LHD, the AS-side waterproof cover 40 is prevented from distorting further near the base of the wiring mounting section 48 for the LHD. Therefore, distortion of the wiring mounting section 48 for the LHD is suppressed, and the wiring LN can be easily fixed to the wiring mounting section 48 for the LHD. Thus, the assembly workability of the wiper device 10 can be improved.

[0075] Furthermore, according to the wiper device 10 of Embodiment 1, the LHD wiring mounting section 48 is provided with a clip fixing hole 48b into which the engaging claw portion 52 of the clip member 50 that supports the wiring LN is inserted, and a pressing surface 48a against which the clip member 50 is pressed.

[0076] This makes it possible to easily attach the wiring LN to the LHD wiring mounting section 48 simply by pressing the clip member 50 against the pressing surface 48a with a pressing force F1. This also improves the assembly workability of the wiper device 10.

[0077] Furthermore, according to the wiper device 10 of Embodiment 1, the AS-side waterproof cover 40 is provided with an umbrella portion 41 that catches water droplets, and the umbrella portion 41 is provided with first reinforcing ribs RB1 to sixth reinforcing ribs RB6 that reinforce the umbrella portion 41, and the first cover-side abutment portion 46a is provided on the first reinforcing rib RB1.

[0078] This makes it possible to give the function of the first cover-side abutment portion 46a to the first reinforcing rib RB1, eliminating the need to provide a separate first cover-side abutment portion 46a in addition to the first reinforcing rib RB1. Therefore, the complexity of the shape of the AS-side waterproof cover 40 is suppressed, and manufacturing costs can be reduced.

[0079] Furthermore, according to the wiper device 10 of Embodiment 1, the AS-side holder member 30 is formed in a rod shape, the first reinforcing rib RB1 extends in a direction that intersects both the extending direction of the AS-side wiper shaft 34 and the extending direction of the AS-side holder member 30, the AS-side holder member 30 and the first reinforcing rib RB1 are arranged to intersect each other, and the second cover-side abutment portion 46b is provided on the side opposite to the side where the first cover-side abutment portion 46a of the first reinforcing rib RB1 is provided, with the AS-side holder member 30 as the center.

[0080] As a result, even if the pressing force F1 becomes greater than expected, the abutment portion 46b on the second cover side can assist in suppressing the distortion of the AS side waterproof cover 40. Therefore, it is possible to avoid damaging components such as the AS side waterproof cover 40 and reduce manufacturing costs.

[0081] Furthermore, according to the wiper device 10 of Embodiment 1, the positioning recess 45a and the first cover side abutment portion 46a are respectively arranged within the projection range AR of the pressing surface 48a along the pressing direction of the clip member 50.

[0082] This makes it possible to efficiently distribute and transmit the pressing force F1 when pressing the clip member 50 to the support portion 32 and the holder-side abutment portion 38. Therefore, distortion of the AS-side waterproof cover 40 can be minimized, and consequently, the reduction in the workability of assembling the wiper device 10 can be further suppressed.

[0083] Furthermore, according to the wiper device 10 of Embodiment 1, the extending direction of the AS-side wiper shaft 34 and the pressing direction of the clip member 50 are perpendicular to each other, so the pressing force F1 can be transmitted directly to the side of the support part 32. Therefore, the pressing force F1 does not need to be applied in the direction that removes the AS-side waterproof cover 40 from the AS-side holder member 30 (upward), which also improves the assembly workability of the wiper device 10.

[0084] Furthermore, the wiper device 10 of Embodiment 1 improves work efficiency, and the AS-side waterproof cover 40 can be standardized for both LHD and RHD. Therefore, it becomes possible to conserve manufacturing energy, and consequently, to achieve the United Nations Sustainable Development Goals (SDGs), particularly Goal 7 (Ensure access to affordable, reliable, sustainable, and modern energy for all) and Goal 13 (Take urgent action to combat climate change and its impacts).

[0085] <Embodiment 2> Figure 8 is a perspective view showing a wiper device for RHD (Embodiment 2). Figure 9 is an enlarged perspective view of the AS side of Figure 8. Figure 10 is a perspective view showing the AS side holder member of Figure 9 by itself. Figure 11 is a view taken from arrow C in Figure 9, showing the degree of distortion of the wiring mounting section for RHD. Figure 12 is a view taken from arrow D in Figure 9 (viewed from below), showing the degree of distortion of the wiring mounting section for RHD. Figure 13 is a perspective view showing the degree of distortion of the wiring mounting section for RHD.

[0086] The wiper device 60 shown in Figure 8 is mounted on a vehicle with a steering wheel on the right side in the direction of travel, and is a wiper device for right-hand drive (RHD) vehicles. Specifically, the RHD wiper device 60 is formed to be substantially mirror-symmetric in the left-right direction compared to the LHD wiper device 10 (see Figure 1) of the first embodiment described above.

[0087] Here, since the wiper device 60 is for RHD, as shown in FIG. 8, in the arrangement direction of the DR side wiper shaft 25 and the AS side wiper shaft 34, the side where the DR side wiper shaft 25 is arranged is the "right side", and the side where the AS side wiper shaft 34 is arranged is the "left side".

[0088] Hereinafter, parts having the same functions as those of the wiper device 10 of the above-described Embodiment 1 are denoted by the same reference numerals, and detailed descriptions thereof are omitted. Further, the AS side holder member 70, the AS side waterproof cover 40, and the wiring LN, which are the main components of the present invention, will be described in detail.

[0089] <AS side holder member> As shown in FIGS. 8 to 10, the AS side holder member 70 forming the wiper device 60 for RHD is formed in a shape that is mirror-symmetrical to each other in the left-right direction of the wiper device 10 for LHD and the wiper device 60 for RHD, as compared with the AS side holder member 30 (see FIG. 3) forming the wiper device 10 for LHD.

[0090] Specifically, as shown in FIG. 10, the AS side holder member 70 includes a holder body 71 extending in the left-right direction. A support portion 72 formed in a cylindrical shape is provided at a substantially central portion along the longitudinal direction of the holder body 71 and closer to the right side. The support portion 72 rotatably supports the AS side wiper shaft 34 (see FIG. 9) via a radial bearing 33.

[0091] Further, a positioning convex portion 72a for positioning the AS side waterproof cover 40 is provided on the outer peripheral portion and the front side of the support portion 72. The positioning convex portion 72a is adapted to fit into a positioning concave portion 45a (see FIG. 4) provided in the fixing portion 45 of the AS side waterproof cover 40.

[0092] Furthermore, a vehicle body fixing portion 73 for fixing the AS side of the wiper device 60 to the vehicle body is provided on the left side along the longitudinal direction of the holder body 71. A rubber bush 36 is also attached to the vehicle body fixing portion 73.

[0093] Furthermore, a frame fixing portion 74 is provided on the right side of the holder body 71 along its longitudinal direction, to which the end of the frame member 24 is fixed. Multiple crimping recesses 37a are also provided on the outer circumference of the frame fixing portion 74.

[0094] Furthermore, in the longitudinal direction of the holder body 71, a holder-side abutment portion 75 is provided between the support portion 72 and the frame fixing portion 74. The holder-side abutment portion 75 has the function of preventing the AS-side waterproof cover 40 from being significantly distorted when the wiring LN (see Figure 9) is attached to the RHD wiring mounting portion 49 of the AS-side waterproof cover 40. The third cover-side abutment portion 47a and the fourth cover-side abutment portion 47b (see Figure 12) of the AS-side waterproof cover 40 can abut against the holder-side abutment portion 75 from its right side.

[0095] The AS-side holder member 70 corresponds to the holder member in the present invention.

[0096] Here, the AS-side waterproof cover 40 attached to the AS-side holder member 70 is a common part with the wiper device 10 for LHD (see Figure 1). However, unlike the wiper device 10 for LHD, the third and fourth cover-side abutment portions 47a and 47b perform abutment function similar to the first and second cover-side abutment portions 46a and 46b. In other words, in the wiper device 60 for RHD, the first and second cover-side abutment portions 46a and 46b do not perform abutment function. Also, in the wiper device 60 for RHD, the LHD wiring mounting portion 48 does not function.

[0097] As shown in Figure 4, in the left-right direction of the AS-side waterproof cover 40, the third cover-side abutment portion 47a is positioned between the fixing portion 45 and the RHD wiring mounting portion 49, and is the point that abuts against the holder-side abutment portion 75 provided on the AS-side holder member 70 when the wiring LN is attached to the RHD wiring mounting portion 49.

[0098] In the RHD wiper device 60, the third cover-side abutment portion 47a corresponds to the cover-side abutment portion in the present invention, and the fourth cover-side abutment portion 47b corresponds to the auxiliary cover-side abutment portion in the present invention. Also, in the RHD wiper device 60, the third reinforcing rib RB3 corresponds to the reinforcing rib in the present invention.

[0099] <Assembly Instructions> Next, the assembly procedure for the RHD wiper device 60 formed as described above will be explained in detail with reference to Figures 11 to 13. In particular, the procedure for attaching the wiring LN to the RHD wiring mounting section 49 will be explained in detail. Note that, for the sake of explanation, only the wiring LN having the AS side holder member 70, the AS side waterproof cover 40, and the clip member 50 is shown in Figures 11 to 13.

[0100] First, prepare the wiring LN with the clip member 50 attached, and also prepare the pre-assembled wiper device 60 for RHD. The installation of the wiring LN to the wiper device 60 is performed, for example, by the vehicle body manufacturer that assembles the vehicle. However, the automotive parts manufacturer that manufactures the wiper device may also pre-install the wiring LN to the wiper device 60.

[0101] As shown by the solid arrows in Figures 11 to 13, the clip member 50 supporting the wiring LN is pressed against the pressing surface 49a of the RHD wiring mounting section 49 with a pressing force F2. At this time, the clip member 50 is positioned facing the RHD wiring mounting section 49 from above the AS-side waterproof cover 40, and the engaging claw portion 52 of the clip member 50 is inserted straight into the clip fixing hole 49b of the RHD wiring mounting section 49.

[0102] As a result, as shown by the dashed arrow M2 in Figures 11 and 13, the RHD wiring mounting portion 49 is pushed downward by the pressing force F2, and the area near the base of the RHD wiring mounting portion 49 is twisted. This twisting force is then transmitted to the umbrella portion 41 via the base of the RHD wiring mounting portion 49, causing the third cover side abutment portion 47a to move to the left.

[0103] The pressing force F2 is first transmitted to the fixing part 45, which is fixed around the axis CT of the support part 72. As a result, the fixing part 45 is strongly pressed against the support part 72 in the vicinity of the first part SP1. At this time, the pressing force F2 acts to press the fixing part 45 downward against the support part 72. Therefore, the pressing force F2 does not cause the AS side waterproof cover 40 to detach from the AS side holder member 70.

[0104] Subsequently, the pressing force F2 acts to further deform the AS-side waterproof cover 40, and as a result, the minute gap between the third cover-side abutment portion 47a and the holder-side abutment portion 75 is closed (see Figure 12). Therefore, at the location of the third portion SP3, the third cover-side abutment portion 47a abuts against the holder-side abutment portion 75, as shown by the dashed arrow P2 in Figure 13. Thus, further deformation of the AS-side waterproof cover 40 near the base portion of the RHD wiring mounting portion 49 is suppressed. This makes it possible to easily insert the engaging claw portion 52 of the clip member 50 into the clip fixing hole 49b of the RHD wiring mounting portion 49.

[0105] Thus, even if the base portion of the RHD wiring mounting portion 49 is twisted (distorted) by the pressing force F2, the holder-side abutment portion 75 at the location of the third portion SP3 positioned between the first portion SP1 and the pressing surface 49a supports (holds firm) the AS-side waterproof cover 40 to prevent further distortion. Therefore, excessive distortion of the AS-side waterproof cover 40 is suppressed, which in turn improves the assembly workability of the wiper device 60.

[0106] Furthermore, the pressing state of the clip member 50 against the pressing surface 49a can be easily confirmed from above and in front of the wiper device 60. Therefore, the operator can easily grasp the degree to which the engaging claw portion 52 is engaged with the clip fixing hole 49b (attachment state).

[0107] Here, for example, if the pressing force F2 becomes too large and the AS-side waterproof cover 40 deforms more significantly, the deformation of the third cover-side abutment portion 47a will increase, and the support capacity of the third cover-side abutment portion 47a alone will be insufficient. In this case, the fourth cover-side abutment portion 47b will abut against the holder-side abutment portion 75 as an auxiliary support. Therefore, even if the pressing force F2 becomes larger than expected, the components such as the AS-side waterproof cover 40 will not be damaged, and the assembly workability of the wiper device 60 will not be reduced.

[0108] The wiper device 60 for RHD of Embodiment 2, formed as described above, can achieve substantially the same effects and advantages as the wiper device 10 for LHD of Embodiment 1 described above.

[0109] The present invention is not limited to the embodiments described above, and it goes without saying that various modifications are possible without departing from the spirit of the invention. For example, in the embodiments described above, the wiping patterns of the wiper device 10 for LHD and the wiper device 60 for RHD are shown to be of the so-called tandem type, but the present invention is not limited to this and can be applied to wiper devices with other wiping patterns such as opposing wiper type.

[0110] Furthermore, in the above embodiments, the wiper device 10 for LHD and the wiper device 60 for RHD are used to wipe the front windshield of the vehicle. However, the present invention is not limited to these, and can also be applied to wipe the rear windshield of the vehicle, or to wipe the windshields of railway vehicles, aircraft, etc.

[0111] Furthermore, the material, shape, dimensions, number, and installation location of each component in the above embodiments are arbitrary as long as they can achieve the present invention, and are not limited to the above embodiments. [Explanation of symbols]
