Description

本発明は、ワイパーブレード、とりわけワイパーブレードカバーの改良に関する。   The present invention relates to improvements in wiper blades, and in particular wiper blade covers.

従来から、ワイパーブレードには、ブレードラバーに弧状に湾曲する長尺形状のバネ板部材を宛がって長尺形状の中央部に設けた取り付け具を介して車両に設けられたワイパーアームに連結されるものが知られている。（例えば、特許文献１参照。）
このワイパーブレードは、ブレードラバーと、バネ板部材をワイパーアーム先端に取り付けるための取り付け具と、ブレードラバーとバネ板部材とを被覆するブレードカバー（スポイラー）とから大略構成されている。 Conventionally, the wiper blade is connected to the wiper arm provided in the vehicle via a long-shaped spring plate member that is curved in an arc shape on the blade rubber and attached to the central part of the long shape. What is done is known. (For example, refer to Patent Document 1.)
The wiper blade generally includes a blade rubber, an attachment for attaching the spring plate member to the tip of the wiper arm, and a blade cover (spoiler) that covers the blade rubber and the spring plate member.

このブレードカバーには、その長手方向中央部に取り付け具を設置するための取り付け開口が設けられており、その取り付け開口には、取り付け具を覆う樹脂製の取り付け開口被覆部材が別部品として取り付けられる。
特開２００３−１４６１９０号公報 The blade cover is provided with a mounting opening for installing a mounting tool in the center in the longitudinal direction thereof, and a resin mounting opening covering member that covers the mounting tool is attached to the mounting opening as a separate part. .

以下に、本発明に係わるワイパーブレードの発明の実施の形態を図面を参照しつつ説明する。   Embodiments of the wiper blade according to the present invention will be described below with reference to the drawings.

（実施例１）
図１は本発明に係わる実施例１のワイパーブレード１０を車両１のワイパーアーム２に適用した状態を示す斜視図、図２は図１に示すワイパーブレード１０の拡大斜視図、図３は図２に示すワイパーブレード１０の分解斜視図である。 Example 1
1 is a perspective view showing a state in which the wiper blade 10 according to the first embodiment of the present invention is applied to a wiper arm 2 of a vehicle 1, FIG. 2 is an enlarged perspective view of the wiper blade 10 shown in FIG. 1, and FIG. It is a disassembled perspective view of the wiper blade 10 shown in FIG.

ワイパーアーム２は図示を略すワイパーモータによって図１に示すように往復動され、例えば、フロントウィンドウガラス３の払拭面４を払拭し、非作動時には、フロントウィンドウガラス３の下辺縁部に停止状態で待機され、その図１において、符号５はワイパーアーム２の往動方向、符号６はワイパーアーム２の復動方向を示している。   The wiper arm 2 is reciprocated as shown in FIG. 1 by a wiper motor (not shown). For example, the wiper arm 4 wipes the wiping surface 4 of the front window glass 3 and is stopped at the lower edge of the front window glass 3 when not operating. In FIG. 1, reference numeral 5 indicates the forward movement direction of the wiper arm 2, and reference numeral 6 indicates the backward movement direction of the wiper arm 2.

ワイパーブレード１０は、長尺形状のブレードラバー１１と、このブレードラバー１１の延びる方向に延びかつ弧状に湾曲するバネ板部材（バーティブラ）１２と、ワイパーアーム２の先端部２ａを取り付けるための取り付け具１７と、ブレードカバー１４とから大略構成されている。   The wiper blade 10 includes an elongated blade rubber 11, a spring plate member (vertebra) 12 that extends in the extending direction of the blade rubber 11 and is curved in an arc shape, and an attachment for attaching the tip 2 a of the wiper arm 2. 17 and a blade cover 14.

ブレードカバー１４は、図３に示すように、弾性材料からなり、側面部１４ｆ、１４ｆ´と上面部１４ｇとを有している。   As shown in FIG. 3, the blade cover 14 is made of an elastic material, and has side surface portions 14f and 14f 'and an upper surface portion 14g.

ブレードカバー１４の内側には、その長手方向の一端から他端に向かって延びる嵌合溝部１４ａが形成されている。この嵌合溝部１４ａはバネ板部材１２を嵌め合わせるために用いられる。   A fitting groove portion 14 a extending from one end in the longitudinal direction to the other end is formed inside the blade cover 14. The fitting groove 14 a is used for fitting the spring plate member 12 together.

その上面部１４ｇの長手方向中央部には、取り付け具１７を設置する取り付け開口１４ｂが形成されている。その取り付け開口１４ｂの上面には、取り付け開口被覆部材としての可撓性切片１４ｃが設けられている。   A mounting opening 14b for installing the mounting tool 17 is formed at the longitudinal center of the upper surface portion 14g. A flexible section 14c as a mounting opening covering member is provided on the upper surface of the mounting opening 14b.

この可撓性切片１４ｃは、バネ板部材１２の幅方向の両側の側面部１４ｆ、１４ｆ´と上面部１４ｇとの境界部分に一対のスリット１４ｄ、１４ｄを形成することにより形成される。この可撓性切片１４ｃは、取り付け開口１４ｂを略半分以上上面から覆う構成とされている。   The flexible section 14c is formed by forming a pair of slits 14d and 14d at the boundary between the side surface portions 14f and 14f 'on the both sides in the width direction of the spring plate member 12 and the upper surface portion 14g. The flexible section 14c is configured to cover the attachment opening 14b from the upper surface by substantially half or more.

そのブレードカバー１４には、その取り付け開口１４ｂの長手方向両側にこの取り付け開口１４ｂを仕切る仕切り壁１４ｑ、１４ｑが形成されている（図３、図２１参照）。この仕切り壁１４ｑ、１４ｑの一方は、可撓性切片１４ｃの回動基部となっている。   The blade cover 14 is formed with partition walls 14q and 14q for partitioning the mounting opening 14b on both sides in the longitudinal direction of the mounting opening 14b (see FIGS. 3 and 21). One of the partition walls 14q and 14q serves as a rotation base of the flexible section 14c.

また、図４に示すように、ブレードカバー１４の側面部１４ｆの上縁部には突起状のリブ部１４ｊが形成され、長手方向中央部の取り付け開口１４ｂを除いた上面部１４ｇは側面部１４ｆから側面部１４f´へ向かって下方に傾斜している。   Further, as shown in FIG. 4, a protruding rib portion 14j is formed on the upper edge portion of the side surface portion 14f of the blade cover 14, and the upper surface portion 14g excluding the attachment opening 14b at the central portion in the longitudinal direction is the side surface portion 14f. It inclines below toward side part 14f '.

そのリブ部１４ｊは、ワイパーブレード１０を車両１に取り付ける際に、車両１の走行方向から車両１に向かって吹く風の下流側に位置される。これにより、車両走行時にブレードカバー１４にあたる空気の流れがその上面部１４ｇの傾斜面に当たってリブ部１４ｊへ向かってスムーズに流れ、その空気の流れはリブ部１４ｊに当たりワイパーブレード１０の全体に払拭面４に向かう方向の均一な圧力が生じる。   The rib portion 14j is positioned on the downstream side of the wind blown from the traveling direction of the vehicle 1 toward the vehicle 1 when the wiper blade 10 is attached to the vehicle 1. As a result, the air flow that hits the blade cover 14 when the vehicle travels hits the inclined surface of the upper surface portion 14g and smoothly flows toward the rib portion 14j, and the air flow hits the rib portion 14j and wipes the entire wiper blade 10. Uniform pressure in the direction toward

このように車両走行時の風がリブ部１４ｊに当たることにより、ワイパーブレード１０が払拭面４側に押しつけられ、高速走行時に、ワイパーブレード１０の復動方向６へ払拭する際に発生しやすい浮き上がりが防止される。   Thus, when the wind of the vehicle travels against the rib portion 14j, the wiper blade 10 is pressed against the wiping surface 4 side, and the lift that tends to occur when wiping in the backward movement direction 6 of the wiper blade 10 during high speed traveling is generated. Is prevented.

ブレードラバー１１は、長尺形状を呈しかつ払拭面４を傷つけることなく払拭面４を摺動可能な弾性部材から構成されている。そのブレードラバー１１は、図４に示すように、払拭面４に接触する断面略逆三角形状の接触部１１ａと、バネ板部材１２が宛がわれる頭部１１ｂと、接触部１１ａと頭部１１ｂとを連結する首部１１ｃと、首部１１ｃから払拭方向に張り出された翼部１１ｄとから大略構成されている。   The blade rubber 11 is formed of an elastic member that has a long shape and can slide on the wiping surface 4 without damaging the wiping surface 4. As shown in FIG. 4, the blade rubber 11 includes a contact portion 11a having a substantially inverted triangular cross section that contacts the wiping surface 4, a head portion 11b to which the spring plate member 12 is addressed, and the contact portion 11a and the head portion 11b. And a wing portion 11d projecting from the neck portion 11c in the wiping direction.

次に、この発明の実施の形態によるブレードカバー１４の組み付けを以下に説明する。   Next, assembly of the blade cover 14 according to the embodiment of the present invention will be described below.

例えば、以下に説明する方法で取り付け具１７は組み立てられる。   For example, the fixture 17 is assembled by the method described below.

まず、図８に示すように、クリップ部材２０の円筒状部２０ｂの円盤状フランジ部２０ａが一対の保持壁１９ｈ、１９ｈの円形状凹所１９ｃに嵌合される。   First, as shown in FIG. 8, the disc-shaped flange portion 20a of the cylindrical portion 20b of the clip member 20 is fitted into the circular recess 19c of the pair of holding walls 19h and 19h.

ついで、一対の保持壁１９ｈ、１９ｈは、図６に示すように、その各円弧状膨出部１９ａを一対の対向壁部１８ａの各円弧状凹所１８ｆにそれぞれ嵌合されるようにして、一対の対向壁部１８ａに組み付けられる。   Next, as shown in FIG. 6, the pair of holding walls 19h and 19h are fitted into the respective arc-shaped recesses 18f of the pair of opposing wall portions 18a so that the respective arc-shaped bulged portions 19a are respectively fitted. It is assembled | attached to a pair of opposing wall part 18a.

その際、可撓性板状部２０ｄの傾斜部２０ｆを連結部１８ｅと一対の挟持爪部１８ｂとの間の空間ｇに侵入させるようにして、連結部１８ｅを一対の可撓性板状部２０ｃ、２０ｄの間に位置させる。   At that time, the inclined portion 20f of the flexible plate-like portion 20d is allowed to enter the space g between the connecting portion 18e and the pair of clamping claws 18b, so that the connecting portion 18e is paired with the pair of flexible plate-like portions. It is located between 20c and 20d.

ついで、リベット２１を各貫通穴１９ｂ、１８ｇ、筒穴２０ｈに挿通し、リベット２１の頭部２１ａから遠い側の先端部２１ｂをカシメて、図６に示すようにクリップ部材２０、一対の保持壁１９ｈ、１９ｈ、対向壁部構成部材１８を一体化する。   Next, the rivet 21 is inserted into the through holes 19b and 18g and the cylindrical hole 20h, and the tip portion 21b far from the head 21a of the rivet 21 is caulked to form the clip member 20 and a pair of holding walls as shown in FIG. 19h and 19h and the opposing wall part structural member 18 are integrated.

また、例えば、ブレードラバー１１は、そのバネ板部材１２の一端部側からその頭部１１ｂを包囲空間１３ｂに通しつつバネ板部材１２の延びる方向に沿って他端部側に向かって移送することにより、そのブレードラバー１１の頭部１１ｂがホルダー部材１３によって保持され、これによって、ブレードラバー１１の頭部１１ｂにバネ板部材１２が宛がわれる。   Further, for example, the blade rubber 11 is transferred from the one end side of the spring plate member 12 toward the other end side along the extending direction of the spring plate member 12 while passing the head portion 11b through the surrounding space 13b. Thus, the head portion 11b of the blade rubber 11 is held by the holder member 13, whereby the spring plate member 12 is addressed to the head portion 11b of the blade rubber 11.

次に、取り付け具１７をバネ板部材１２の長手方向中央部１５に取り付ける。   Next, the attachment 17 is attached to the longitudinal center portion 15 of the spring plate member 12.

続いて、ブレードラバー１１とバネ板部材１２と取り付け具１７とからなる組付け体は、そのバネ板部材１２が、ブレードカバー１４の嵌合溝部１４ａに嵌め合わされるようにして、ブレードカバー１４によって上から被覆される。   Subsequently, the assembly comprising the blade rubber 11, the spring plate member 12, and the fixture 17 is attached by the blade cover 14 so that the spring plate member 12 is fitted into the fitting groove 14 a of the blade cover 14. Covered from above.

これにより取り付け具１７は、ブレードカバー１４の中央部の取り付け開口１４ｂに位置される。   As a result, the attachment 17 is positioned in the attachment opening 14 b at the center of the blade cover 14.

次に、ワイパーアーム２を取り付け具１７に装着する際には、図２０、図２１に示すＺ方向に、可撓性切片１４ｃをめくり上げて、ワイパーアーム２の先端部２ａの係合穴２ｂを取り付け具１７のクリップ部材２０の係合爪２０ｅに係合させる。これにより、ワイパーアーム２が取り付け具１７に装着される。   Next, when the wiper arm 2 is attached to the fixture 17, the flexible section 14c is turned up in the Z direction shown in FIGS. 20 and 21, and the engagement hole 2b of the tip 2a of the wiper arm 2 is turned on. Is engaged with the engaging claw 20e of the clip member 20 of the fixture 17. As a result, the wiper arm 2 is attached to the fixture 17.

この発明の実施の形態によれば、ブレードカバー１４の上面部１４ｇに可撓性切片１４ｃが上面部１４ｇと一体的にスリット１４ｄ、１４ｄにより形成されているので、可撓性切片１４ｃを軽く撓ませてワイパーアーム２を取り付け具１７に装着でき、取り付け作業が容易となる。   According to the embodiment of the present invention, since the flexible section 14c is formed integrally with the upper surface portion 14g by the slits 14d and 14d on the upper surface portion 14g of the blade cover 14, the flexible section 14c is lightly bent. Thus, the wiper arm 2 can be attached to the attachment 17 and the attachment work becomes easy.

この発明による弾性材料からなるブレードカバー１４よれば、従来のような取り付け開口被覆部材が樹脂製の別部品から構成されかつ結合力が強固なものと比べ、その取り付け作業が容易となり、従来のような取り付け時に必要とされていた工具が不要になる。   According to the blade cover 14 made of an elastic material according to the present invention, the mounting operation is easier than in the conventional case where the mounting opening covering member is made of a separate resin part and has a strong bonding force. This eliminates the need for the tools that were needed for proper installation.

また、この可撓性切片１４ｃにより、取り付け開口１４ｂが覆われており、外部からの異物が取り付け開口１４ｂの内部に侵入しにくい構造となっているので、従来のように取り付け開口１４ｂを別部品で覆うものに比べてコストがかかるという不都合、取り付け開口被覆部材と取り付け具１７との間に隙間が生じやすいという不都合、組み付け作業が面倒であるという不都合、ひいては、払拭不良を起こすという不都合を回避できる。   In addition, since the attachment opening 14b is covered with the flexible section 14c and foreign matter from the outside hardly enters the inside of the attachment opening 14b, the attachment opening 14b is separated from the conventional one. Avoid the disadvantages of being more expensive than those covered by the cover, the inconvenience of creating a gap between the attachment opening covering member and the fixture 17, the inconvenience of cumbersome assembly work, and the inconvenience of inadequate wiping. it can.

なお、このブレードラバー１１は、図１に示す往動方向５に可動されるときと図１に示す復動方向６に可動されるときとでは払拭面４の法線Ｎに対する傾斜角度θが逆向きとなるものであり、例えば、図２２に示すように、ブレードラバー１１が払拭面４に対して往動方向５に移動するときには、一対の保持壁１９ｈ、１９ｈに対して対向壁部構成部材１８が相対的に回動し、払拭面４の法線Ｎに対する傾斜角度はθとなり、例えば、図２３に示すように、ブレードラバー１１が払拭面４に対して復動方向６に移動するときには、一対の保持壁１９ｈ、１９ｈに対して対向壁部構成部材１８が反対方向に相対的に回動し、払拭面４の法線Ｎに対する傾斜角度は−θとなる。   Note that the blade rubber 11 has the inclination angle θ with respect to the normal N of the wiping surface 4 reversed when it is moved in the forward movement direction 5 shown in FIG. 1 and when it is moved in the backward movement direction 6 shown in FIG. For example, as shown in FIG. 22, when the blade rubber 11 moves in the forward movement direction 5 with respect to the wiping surface 4, as shown in FIG. 22, the opposing wall portion constituting member with respect to the pair of holding walls 19h, 19h. 18 is relatively rotated, and the inclination angle of the wiping surface 4 with respect to the normal line N is θ. For example, when the blade rubber 11 moves in the backward movement direction 6 with respect to the wiping surface 4 as shown in FIG. The opposing wall portion constituting member 18 rotates relatively in the opposite direction with respect to the pair of holding walls 19h, 19h, and the inclination angle of the wiping surface 4 with respect to the normal line N becomes −θ.

払拭の際のブレードラバー１１の回動中心としての直交方向軸線Ｇ２がワイパーアーム２に対するブレードラバー１１の回動軸線としての横断方向軸線Ｇ１とが交点Ｏを形成するようにして直交しているので、横断方向軸線Ｇ１と直交方向軸線Ｇ２との高さ方向のずれをなくした分だけ、取り付け具１７の高さ方向の寸法を小さくでき、取り付け具１７のコンパクト化を図ることができる。また、組み付け部品点数を少なくして、ブレードラバー１１を直交方向軸線Ｇ２の回りに回動させることが可能となる。   Since the orthogonal axis G2 as the rotation center of the blade rubber 11 at the time of wiping is orthogonal to the transverse axis G1 as the rotation axis of the blade rubber 11 with respect to the wiper arm 2 so as to form an intersection point O. The dimension in the height direction of the fixture 17 can be reduced by an amount corresponding to the displacement in the height direction between the transverse axis G1 and the orthogonal axis G2, and the fixture 17 can be made compact. Further, it is possible to rotate the blade rubber 11 around the orthogonal axis G2 by reducing the number of parts to be assembled.

更に、一対の保持壁１９ｈ、１９ｈと一対の対向壁部１８ａとの間には隙間Ｈが存在するので、ブレードラバー１１の往復移動の際のブレードラバー１１の反転のスムーズ化を図ることができる。加えて、クリップ部材２０の筒穴２０ｈの形状を変更するのみで、フロントウィンドウガラス３の払拭面４の湾曲形状の異なるものに対して適切な払拭角度を得ることができる。
（変形例）
図２４ないし図２６は、先に述べたブレードカバー１４の可撓性切片１４ｃの変形例を示している。 Further, since there is a gap H between the pair of holding walls 19h, 19h and the pair of opposing wall portions 18a, the blade rubber 11 can be smoothly reversed when the blade rubber 11 reciprocates. . In addition, an appropriate wiping angle can be obtained with respect to the wiping surface 4 of the front window glass 3 having a different curved shape only by changing the shape of the cylindrical hole 20h of the clip member 20.
(Modification)
24 to 26 show modifications of the flexible section 14c of the blade cover 14 described above.

これらの図２４ないし図２６に示される可撓性切片１４ｃには、その幅方向中央部に、ワイパーアーム２先端のU字形状部２ｃに当接する湾曲当接部１４ｈとバネ板部材１２の長手方向に延びる膨出部１４ｈ´とが形成されている。   The flexible section 14c shown in FIGS. 24 to 26 includes a curved contact portion 14h that contacts the U-shaped portion 2c at the tip of the wiper arm 2 and the length of the spring plate member 12 at the center in the width direction. A bulging portion 14h ′ extending in the direction is formed.

この湾曲当接部１４ｈは、ワイパーアーム２の先端のＵ字形状部２ｃに当接することにより、可撓性切片１４ｃはその動きが安定するのでかつ膨出部１４ｈ´が可撓性切片１４ｃの補強部としての作用を果たすので、ワイパーアーム２の作動中に可撓性切片１４ｃがワイパーアーム２の先端のＵ字形状部２ｃの回動によりめくれ上がるのが極力阻止される。   The curved abutting portion 14h abuts on the U-shaped portion 2c at the tip of the wiper arm 2, so that the movement of the flexible section 14c is stabilized and the bulging portion 14h ′ is formed on the flexible section 14c. Since it functions as a reinforcing portion, the flexible section 14c is prevented from being turned up by turning the U-shaped portion 2c at the tip of the wiper arm 2 during the operation of the wiper arm 2.

以上、この発明による実施例１では、弾性材料からなるブレードカバー１４の可撓性切片１４ｃを、バネ板部材１２の幅方向の両側の側面部１４ｆ、１４ｆ´と上面部１４ｇとの境界部分に一対のスリット１４ｄ、１４ｄを形成することにより形成したが、以下に説明する実施例２のような構成とすることもできる。
（実施例２）
図２７は、実施例２に係わるブレードカバー１４´の斜視図である。この可撓性切片１４ｃ´は、ブレードカバー１４´の上面部１４ｇ´にその幅方向中央部分にその長手方向に延びる1個のスリット１４ｄ´を形成することにより形成されている。 As described above, in the first embodiment according to the present invention, the flexible section 14c of the blade cover 14 made of an elastic material is provided at the boundary portion between the side surface portions 14f, 14f ′ and the upper surface portion 14g on both sides in the width direction of the spring plate member 12. Although formed by forming a pair of slits 14d, 14d, a configuration as in Example 2 described below can also be adopted.
(Example 2)
FIG. 27 is a perspective view of the blade cover 14 ′ according to the second embodiment. The flexible section 14c ′ is formed by forming one slit 14d ′ extending in the longitudinal direction at the center portion in the width direction on the upper surface portion 14g ′ of the blade cover 14 ′.

図２８に示すように、この可撓性切片１４ｃ´、１４ｃ´は、実施例１と同様に、取り付け開口１４ｂ´に設置されている取り付け具１７を覆っている。   As shown in FIG. 28, the flexible sections 14c ′ and 14c ′ cover the attachment 17 installed in the attachment opening 14b ′ as in the first embodiment.

このものでは、ブレードカバー１４´の上面部１４ｇ´に、長手方向に延びる１個のスリット１４ｄ´を形成することにより可撓性切片１４ｃ´、１４ｃ´を形成したので、スリット１４ｄ´を境にしてかつその幅方向両側の側面部１４ｆ、１４ｆ´と可撓性切片１４ｃ´、１４ｃ´との境界部分を回動基部として矢印Ｚ´方向に両可撓性切片１４ｃ´、１４ｃ´をめくり上げることにより、ワイパーアーム２の先端２ａを容易にクリップ部材２０に装着できる。   In this case, the flexible sections 14c 'and 14c' are formed by forming one slit 14d 'extending in the longitudinal direction on the upper surface portion 14g' of the blade cover 14 ', so that the slit 14d' serves as a boundary. In addition, the flexible sections 14c 'and 14c' are turned up in the direction of the arrow Z 'with the boundary portion between the side portions 14f and 14f' on both sides in the width direction and the flexible sections 14c 'and 14c' as the rotation base. Thus, the tip 2a of the wiper arm 2 can be easily attached to the clip member 20.

この実施例２の可撓性切片１４ｃ´、１４ｃ´の回動基部からスリット１４ｄ´が形成されている先端までの幅方向の長さは、実施例１の可撓性切片１４ｃの回動基部から先端までの長手方向の長さに比べて短い。   The length in the width direction from the rotation base of the flexible sections 14c ′ and 14c ′ of the second embodiment to the tip where the slit 14d ′ is formed is the rotation base of the flexible section 14c of the first embodiment. It is shorter than the length in the longitudinal direction from the tip to the tip.

従って、実施例１の可撓性切片１４ｃをその回動基部を支点にして撓ませたときにこの可撓性切片１４ｃに生じる反力に較べて、この実施例２の可撓性切片１４ｃ´、１４ｃ´をその回動基部を支点にして撓ませたときに生じる反力が大きくなり、ワイパーアーム２の作動中に、可撓性切片１４ｃ´、１４ｃ´のめくり上がり量が、実施例１の可撓性切片１４ｃよりも小さくなる。   Accordingly, the flexible section 14c ′ of the second embodiment is compared with the reaction force generated in the flexible section 14c when the flexible section 14c of the first embodiment is bent with its rotating base as a fulcrum. , 14c 'is bent with the rotating base as a fulcrum, the reaction force generated becomes large, and the amount of roll-up of the flexible sections 14c', 14c 'during the operation of the wiper arm 2 is the same as in Example 1. Smaller than the flexible section 14c.

その結果、可撓性切片１４ｃ´、１４ｃ´に実施例１の変形例で示した膨出部を設けなくとも、ワイパーアーム２の作動中の可撓性切片１４ｃ´、１４ｃ´のめくれを防止でき、見栄えが良好である。   As a result, the flexible sections 14c ′ and 14c ′ can be prevented from being turned over while the wiper arm 2 is in operation without providing the bulging portion shown in the modification of the first embodiment. It looks good and looks good.

以上、実施例１、実施例２では、一体構成のブレードカバー１４について説明したが、ブレードカバー１４はこれに限るものではなく、例えば、弾性材料からなるブレードカバー１４を、可撓性切片１４ｃを有する中央カバー部、その両側にそれぞれ位置する左カバー部、右カバー部の三分割構成としてもよい。
As described above, in the first and second embodiments, the integrally configured blade cover 14 has been described. However, the blade cover 14 is not limited to this. For example, the blade cover 14 made of an elastic material is used as the flexible section 14c. It is good also as a 3 division | segmentation structure of the center cover part which has, the left cover part located in the both sides, and the right cover part, respectively.
