Description
本発明は、車両用のワイパブレード及びワイパに関するものである。 The present invention relates to a wiper blade and a wiper for a vehicle.
従来から車両用のワイパは、ワイパアームとワイパアームに連結されるワイパブレードからなる。そして、ワイパブレードとしては、ブレードラバーを保持するホルダ本体と、ホルダ本体に対してブレードラバーの幅方向に沿った軸線周りに回動可能に連結される連結部材とを備え、連結部材に設けられた押下可能な係止凸部がワイパアームに設けられた係止孔に嵌り着脱方向に係合することでワイパアームに連結されるものがある。そして、このようなワイパブレードの連結部材としては、係止凸部がワイパアームの抜け方向で連結部材の本体と連結され、その連結部分がヒンジ部として係止凸部のブレードラバーの幅方向に沿った軸線周りの回動を許容し係止凸部が押下可能とされたものがある（例えば、特許文献１参照）。このワイパでは、係止凸部にワイパアームの抜け方向の力が掛かっても、ヒンジ部が係止凸部に対して反対側（即ち係止凸部よりもワイパアームの装着方向側）に設けられたものに比べて、外れにくいとされている。 Conventionally, a wiper for a vehicle includes a wiper arm and a wiper blade connected to the wiper arm. The wiper blade includes a holder main body that holds the blade rubber, and a connecting member that is connected to the holder main body so as to be rotatable about an axis along the width direction of the blade rubber. Some of the pressing protrusions that can be pressed are fitted into locking holes provided in the wiper arm and engaged with the wiper arm by engaging in the attaching / detaching direction. As a connecting member for such a wiper blade, the engaging projection is connected to the main body of the connecting member in the direction in which the wiper arm is removed, and the connecting portion serves as a hinge portion along the width direction of the blade rubber of the engaging projection. There is one in which the rotation around the axis is allowed and the locking projection can be pressed down (see, for example, Patent Document 1). In this wiper, even if a force in the removal direction of the wiper arm is applied to the locking convex portion, the hinge portion is provided on the opposite side to the locking convex portion (that is, the wiper arm mounting direction side than the locking convex portion). It is said that it is hard to come off compared to things.
しかしながら、上記のように係止凸部の着脱方向に連結部分（ヒンジ部）があり、該連結部分でブレードラバーの幅方向に沿った軸線周りの回動（係止凸部の弾性撓み）が許容される構成では、ワイパブレードとワイパアームの外れ難さが、連結部分の撓み易さ（回動し易さ）や強度に大きく依存してしまうことになる。そして、例えば、連結部分（ヒンジ部）の強度を高くしてワイパブレードとワイパアームが外れ難い構成とすると、作業者が係止凸部を押下し難くなり、作業者による装着時や取外し時の作業性が低下してしまうことになる。 However, as described above, there is a connecting portion (hinge portion) in the attaching / detaching direction of the locking convex portion, and rotation around the axis along the width direction of the blade rubber (elastic deflection of the locking convex portion) at the connecting portion. In an allowable configuration, the difficulty of detaching the wiper blade and the wiper arm greatly depends on the ease of bending (easy to rotate) and the strength of the connecting portion. For example, if the strength of the connecting part (hinge part) is increased so that the wiper blade and the wiper arm are difficult to be detached, it becomes difficult for the operator to press down the locking convex part, and the work at the time of installation or removal by the operator is difficult. Will be reduced.
本発明は、上記問題点を解決するためになされたものであって、その目的は、ワイパブレードとワイパアームを強固に連結することができるとともに、装着時や取外し時の作業性を向上させることができるワイパブレード及びワイパを提供することにある。 The present invention has been made to solve the above-mentioned problems, and its purpose is to firmly connect the wiper blade and the wiper arm, and to improve workability at the time of mounting and removal. It is to provide a wiper blade and a wiper that can be used.
上記課題を解決するワイパブレードは、払拭面を払拭するためのブレードラバーを保持するホルダ本体と、前記ホルダ本体に対して前記ブレードラバーの幅方向に沿った軸中心で回動可能に連結される連結部材とを備え、前記連結部材に設けられた係止凸部がワイパアームに設けられた係止孔に嵌り着脱方向に係合することで該ワイパアームに連結されるワイパブレードであって、前記連結部材は、上壁と、該上壁の前記幅方向両端部から下方に延びる側壁と、前記ブレードラバーの幅方向に延びて先端部が前記係止凸部に接続されるとともに基端部が前記側壁の上下方向中間部に接続されるとともに前記上壁と前記側壁との境界部分に折曲部を有する弾性片部と、前記上壁から上方に突出するように設けられた前記係止凸部の前記ワイパアームの抜け方向への移動を規制する規制部とを有する。 A wiper blade that solves the above problems is connected to a holder main body that holds a blade rubber for wiping the wiping surface, and is rotatable with respect to the holder main body about an axis along the width direction of the blade rubber. A wiper blade that is connected to the wiper arm by engaging a locking projection provided in the connecting member with a locking hole provided in the wiper arm and engaging in a detaching direction. The member includes an upper wall, side walls extending downward from both end portions in the width direction of the upper wall, extending in the width direction of the blade rubber and having a distal end portion connected to the locking projection and a proximal end portion An elastic piece portion connected to the vertical middle portion of the side wall and having a bent portion at a boundary portion between the upper wall and the side wall, and the locking convex portion provided so as to protrude upward from the upper wall said Waipaa of And a regulating portion for regulating the move of the omission direction beam.
同構成によれば、連結部材は弾性片部がワイパアームの着脱方向とは異なる方向に延びているため、ワイパアームの抜け方向へ力が作用しても弾性片部の撓みは係止凸部の押下方向とは異なる方向、即ち、係止凸部と係止孔との係合を解除する方向には生じない。これにより、ワイパアームとワイパブレードとの連結が不用意には外れ難く、その連結をより強固なものとすることができる。しかも、連結部材はワイパアームの抜け方向への係止凸部の移動を規制する規制部を有するため、係止凸部にワイパアームの抜け方向の力が掛かっても、規制部によって同方向に係止凸部が移動することは規制される。即ち、連結部材は、係止凸部にワイパアームの抜け方向の力が掛かると、弾性片部が撓んで係止凸部が前記抜け方向に移動しようとするがその力は規制部にて受け止められ係止凸部の移動が規制される。よって、ワイパアームとワイパブレードとの連結を強固なものとしながらも弾性片部を撓み易くして係止凸部を作業者が押下し易くすることができ、作業者による装着時や取外し時の作業性を向上させることができる。 According to this configuration, since the elastic piece portion of the connecting member extends in a direction different from the direction in which the wiper arm is attached / detached, even if a force acts in the direction in which the wiper arm is detached, the elastic piece portion is not bent by the locking projection. It does not occur in a direction different from the direction, that is, a direction in which the engagement between the locking projection and the locking hole is released. As a result, the connection between the wiper arm and the wiper blade is unlikely to be inadvertently disconnected, and the connection can be made stronger. In addition, since the connecting member has a restricting portion that restricts the movement of the locking projection in the direction in which the wiper arm is pulled out, even if a force in the pulling direction of the wiper arm is applied to the locking projection, the connecting member is locked in the same direction. The movement of the convex portion is restricted. In other words, when a force in the direction of removal of the wiper arm is applied to the locking projection, the connecting member bends the elastic piece and the locking projection moves in the direction of removal, but the force is received by the regulating portion. The movement of the locking projection is restricted. Therefore, the elastic piece can be easily bent and the operator can easily press the locking projection while strengthening the connection between the wiper arm and the wiper blade. Can be improved.
また、係止凸部は、連結部材の上壁から上方に突出するように設けられ、弾性片部は、その先端部が前記係止凸部に接続され基端部が連結部材の側壁の上下方向中間部に接続されるため、例えば、弾性片部の基端部が上壁に設けられるような構成に比べて、弾性片部の長さを容易に長く確保することができる。これにより、例えば、弾性片部を容易に撓み易くすることができる。
また、弾性片部は、連結部材の上壁と側壁との境界部分に折曲部を有するため、弾性片部の基端部（より詳しくは、弾性片部の側壁との接続部位）を撓み軸として撓むだけでなくその折曲部を軸中心としても撓み易くなり、作業者が係止凸部をより押下し易くなり、作業者による装着時や取外し時の作業性をより向上させることができる。
上記ワイパブレードにおいて、前記弾性片部は、前記係止凸部の前記着脱方向の寸法よりも小さい寸法の狭部を有することが好ましい。
同構成によれば、弾性片部は、係止凸部の前記着脱方向の寸法よりも小さい寸法の狭部を有するため、係止凸部の寸法を確保して例えば作業者が指等により押下し易い構成としながらも弾性片部を撓み易くすることができる。
The locking projection is provided so as to protrude upward from the upper wall of the coupling member, and the elastic piece has a distal end connected to the locking projection and a base end located above and below the side wall of the coupling member. Since it is connected to the middle portion in the direction, for example, the length of the elastic piece portion can be easily secured longer than the configuration in which the base end portion of the elastic piece portion is provided on the upper wall. Thereby, for example, the elastic piece portion can be easily bent.
Further, since the elastic piece portion has a bent portion at the boundary portion between the upper wall and the side wall of the connecting member, the base end portion of the elastic piece portion (more specifically, the connection portion with the side wall of the elastic piece portion) is bent. Not only bend as a shaft but also bend easily with its bent part as the center of the axis, making it easier for the operator to press down on the locking projection, and improving the workability at the time of installation and removal by the operator Can do.
The said wiper blade WHEREIN: It is preferable that the said elastic piece part has a narrow part with a dimension smaller than the dimension of the said attachment / detachment direction of the said latching convex part.
According to this configuration, since the elastic piece portion has a narrow portion having a size smaller than the size of the locking projection in the attaching / detaching direction, the size of the locking projection is secured and the operator presses the finger with a finger or the like. The elastic piece portion can be easily bent while the configuration is easy to do.
上記ワイパブレードにおいて、前記弾性片部は、前記上壁及び前記側壁の少なくとも一方の同一平面上にスリットにて区画されて形成されるものである。In the wiper blade, the elastic piece portion is formed by being partitioned by a slit on the same plane of at least one of the upper wall and the side wall.
上記ワイパブレードにおいて、前記係止凸部は、前記上壁及び前記側壁の少なくとも一方の同一平面上にスリットにて区画されて形成されるものであり、前記規制部は、前記係止凸部と対応した前記上壁又は前記側壁の前記スリット側端面であることが好ましい。 In the above wiper blade, the front Kigakaritometotsu portion, which is formed by partitioned by the slit on at least one same plane of said top wall and said side walls, said regulating portion, the engaging convexed latch portion It is preferable that it is the slit side end surface of the upper wall or the side wall corresponding to.
同構成によれば、係止凸部及び弾性片部は、連結部材の上壁及び側壁の少なくとも一方の同一平面上にスリットにて区画されて形成されるものであり、規制部は、係止凸部と対応した上壁又は側壁のスリット側端面であるため、スリットの形状を設定するだけでそれらを容易に一体成形することかできる。又、弾性片部及び係止凸部に対する規制部（スリット側端面）の位置関係（それらの間隔等）を容易に高精度に製造することができる。よって、安定した品質の連結部材を安価に製造することができる。 According to the same configuration, the locking convex portion and the elastic piece portion are formed by being partitioned by the slit on the same plane of at least one of the upper wall and the side wall of the connecting member. Since it is the slit side end surface of the upper wall or side wall corresponding to the convex part, they can be easily integrally formed only by setting the shape of the slit. In addition, the positional relationship (the interval between them) of the restricting portion (slit side end surface) with respect to the elastic piece portion and the locking convex portion can be easily manufactured with high accuracy. Therefore, a stable quality connecting member can be manufactured at low cost.
上記課題を解決するワイパは、上記ワイパブレードと、ワイパアームとを備える。
同構成によれば、ワイパにおいて、上記効果を得ることができる。

FIG. 12 illustrates a state in which the clip 17 has been rotated to the maximum in the wiping enabled state. FIG. 13 shows a state in which the clip 17 is rotated to the maximum in the non-wiping state (for example, a so-called lockback state) (a state in which the guide convex portion 17j is in contact with a terminal position above the guide groove 13f). Is illustrated.
即ち、突起４ｄは、クリップ１７に先端連結部４が組み付けられた状態（図８参照）からクリップ１７に対して先端連結部４を長手方向（抜け方向）に相対移動させた際（図１１参照）に抜け止め壁部１３ｇと長手方向に当接して、それ以上の長手方向の相対移動（抜け）を規制するように設けられている。又、ワイパ１が車両に取り付けられ払拭部１１ａがフロントガラスに押圧接触した状態では、フロントガラス（湾曲面）に沿ってクリップ１７の回動角度が変化するが、その払拭時回動範囲Ｘ１（図１２参照）では突起４ｄと抜け止め壁部１３ｇが前記長手方向に当接することで、それ以上の長手方向の相対移動（抜け）は規制されるように設定されている。更に、本実施形態では、例えば、所謂ロックバック状態でクリップ１７の回動角度が変化しても、その非払拭時回動範囲Ｘ２（図１３参照）では突起４ｄと抜け止め壁部１３ｇが前記長手方向に当接することで、それ以上の長手方向の相対移動（抜け）は規制されるように設定されている。又、突起４ｄは、抜け止め壁部１３ｇと長手方向に当接した状態（図１１〜図１３参照）では、抜け止め壁部１３ｇに沿って上下方向の移動が許容（図１１では、抜け止め壁部１３ｇとクリップ１７の両側壁１７ａの長手方向他端部との間の上下方向に沿って延びる隙間Ｓを通って上下方向の移動が許容）されるように設けられている。尚、図１１〜図１３では、係止凸部１７ｋをそのまま図示しているが、実際は、例えば係止凸部１７ｋが破損した状態や押下された状態を想定した図である。 That is, the protrusion 4d moves when the distal end connecting portion 4 is moved relative to the clip 17 in the longitudinal direction (disengagement direction) from the state where the distal end connecting portion 4 is assembled to the clip 17 (see FIG. 8) (see FIG. 11). ) In contact with the retaining wall portion 13g in the longitudinal direction so as to restrict further relative movement (disengagement) in the longitudinal direction. When the wiper 1 is attached to the vehicle and the wiping portion 11a is in press contact with the windshield, the rotation angle of the clip 17 changes along the windshield (curved surface). In FIG. 12, the protrusion 4d and the retaining wall portion 13g are in contact with each other in the longitudinal direction so that further relative movement (disengagement) in the longitudinal direction is restricted. Furthermore, in this embodiment, for example, even if the rotation angle of the clip 17 changes in a so-called lock-back state, the protrusion 4d and the retaining wall portion 13g are disposed in the non-wiping rotation range X2 (see FIG. 13). By abutting in the longitudinal direction, the relative movement (disconnection) in the longitudinal direction beyond that is set to be regulated. Further, the protrusion 4d is allowed to move in the vertical direction along the retaining wall portion 13g in a state where the projection 4d is in contact with the retaining wall portion 13g in the longitudinal direction (see FIGS. 11 to 13). It is provided so as to be allowed to move in the vertical direction through a gap S extending along the vertical direction between the wall portion 13g and the other longitudinal end portion of both side walls 17a of the clip 17. 11 to 13, the locking projection 17k is illustrated as it is. However, in actuality, for example, the locking projection 17k is assumed to be damaged or pressed.
これにより、組み付ける際は、クリップ１７に対して先端連結部４をまず下方に相対移動させた後、先端連結部４を長手方向に相対移動させて（係合凹部４ｃを係合凸部１７ｆに係合させて）組み付けることになる。又、逆に、取り外す際は、クリップ１７に対して先端連結部４をまず長手方向に相対移動させ（係合凹部４ｃを係合凸部１７ｆから外し）た後、先端連結部４を上方に相対移動させて取り外すことになる。 As a result, when assembling, the tip connecting portion 4 is first relatively moved downward with respect to the clip 17, and then the tip connecting portion 4 is relatively moved in the longitudinal direction (the engaging recess 4c becomes the engaging protrusion 17f). Will be assembled). On the other hand, when removing, the tip connecting portion 4 is first moved relative to the clip 17 in the longitudinal direction (the engaging concave portion 4c is removed from the engaging convex portion 17f), and then the tip connecting portion 4 is moved upward. It will be removed by relative movement.
又、図８に示すように、突起４ｄは、クリップ１７に先端連結部４が組み付けられた状態で、クリップ１７の前記上方下端面１７ｉと当接する位置に形成されている。
又、突起４ｄは、クリップ１７に先端連結部４が組み付けられた状態で、前記案内凸部１７ｊ（図７参照）の下端と当接する位置に形成され、前記案内溝１３ｆ（図５参照）の下方の終端と当接することで連結レバー１３に対するクリップ１７及び先端連結部４の一方の回動を規制するように設けられている。即ち、突起４ｄは、クリップ１７に先端連結部４が組み付けられた状態では、前記案内凸部１７ｊと一体的となり剛性を互いに高め合いつつ、前記一方の回動を規制するように設けられている。
Further, as shown in FIG. 8, the protrusion 4 d is formed at a position in contact with the upper lower end surface 17 i of the clip 17 in a state where the tip connecting portion 4 is assembled to the clip 17.
Further, the protrusion 4d is formed at a position in contact with the lower end of the guide convex portion 17j (see FIG. 7) in a state where the tip connecting portion 4 is assembled to the clip 17, and is formed in the guide groove 13f (see FIG. 5). It is provided so as to restrict the rotation of one of the clip 17 and the tip connecting portion 4 with respect to the connecting lever 13 by contacting the lower end. That is, the protrusion 4d is provided so as to restrict the rotation of the one while being integrated with the guide convex portion 17j and enhancing the rigidity in the state where the tip connecting portion 4 is assembled to the clip 17. .
又、図２、図４、及び図１０に示すように、先端連結部４の上被覆壁４ａには、クリップ１７に組み付けられた状態（図８参照）であって前記係止凸部１７ｋが押下されていない状態で該係止凸部１７ｋが嵌合されて該係止凸部１７ｋと着脱方向（長手方向）に係合する係止孔４ｅが形成されている。これにより、係止凸部１７ｋに何らかの外力が加わらなければ、先端連結部４とクリップ１７とが長手方向に相対移動、すなわち、ワイパアーム２とワイパブレード３との連結が外れてしまうことが防止されている。 As shown in FIGS. 2, 4 and 10, the upper covering wall 4a of the tip connecting portion 4 is assembled to the clip 17 (see FIG. 8), and the locking convex portion 17k is formed on the upper covering wall 4a. A locking hole 4e is formed to be engaged with the locking projection 17k in the attaching / detaching direction (longitudinal direction) by being engaged with the locking projection 17k when not pressed. As a result, if any external force is not applied to the locking projection 17k, the distal end connecting portion 4 and the clip 17 are prevented from relatively moving in the longitudinal direction, that is, the connection between the wiper arm 2 and the wiper blade 3 is not released. ing.
又、図３に示すように、先端連結部４の両側被覆壁４ｂには、上下方向に前記バッキング１２と一致する位置まで下方に延びたラップ部４ｆが形成されている。
次に、上記のように構成されたワイパ１の作用について説明する。
Further, as shown in FIG. 3, wrap portions 4 f extending downward to a position that coincides with the backing 12 in the vertical direction are formed on both side covering walls 4 b of the tip connecting portion 4.
Next, the operation of the wiper 1 configured as described above will be described.
上記ワイパ１では、ワイパアーム２とその先端連結部４に固定されたクリップ１７に対して（クリップ１７を除く）ワイパブレード３が回動可能とされる。そして、ワイパアーム２の先端連結部４が図示しない付勢機構によりフロントガラス（払拭面）側に付勢されることで、その付勢力がクリップ１７、連結レバー１３、バッキング１２を介してブレードラバー１１に伝達されて、ブレードラバーの払拭部１１ａが長手方向全長に亘ってフロントガラス（払拭面）に押圧接触される。又、走行時には、フィン部１６にて走行風がフロントガラス（払拭面）側への押圧力に変換されて、ブレードラバーの払拭部１１ａがフロントガラス（払拭面）に押圧接触される。これらのことから、ワイパアーム２がピボット軸中心に往復回動されると、良好な払拭動作が行われる。 In the wiper 1, the wiper blade 3 (excluding the clip 17) is rotatable with respect to the wiper arm 2 and the clip 17 fixed to the tip connecting portion 4. The leading end connecting portion 4 of the wiper arm 2 is urged toward the windshield (wiping surface) by an urging mechanism (not shown), so that the urging force is applied to the blade rubber 11 via the clip 17, the connecting lever 13, and the backing 12. The blade rubber wiping portion 11a is pressed and contacted with the windshield (wiping surface) over the entire length in the longitudinal direction. Further, during traveling, the traveling air is converted into a pressing force toward the windshield (wiping surface) by the fin portion 16, and the wiping portion 11a of the blade rubber is pressed against the windshield (wiping surface). For these reasons, when the wiper arm 2 is reciprocally rotated about the pivot axis, a good wiping operation is performed.
次に、上記実施の形態の特徴的な効果を以下に記載する。
（１）クリップ１７は、ワイパアーム２の着脱方向（ワイパブレード３の長手方向）とは異なる方向（本実施形態では直交方向）に延びて先端部に係止凸部１７ｋが設けられる弾性片部１７ｌを有するため、ワイパアーム２の抜け方向へ力が作用しても弾性片部１７ｌの撓みは係止凸部１７ｋと係止孔４ｅとの係合を解除する方向には生じない。これにより、ワイパアーム２とワイパブレード３との連結が不用意には外れ難く、その連結をより強固なものとすることができる。しかも、クリップ１７は、ワイパアーム２の抜け方向への係止凸部１７ｋの移動を規制する規制部１７ｍを有するため、係止凸部１７ｋにワイパアーム２の抜け方向の力が掛かっても、図１４に示すように、規制部１７ｍによって同方向に係止凸部１７ｋが移動することは規制される。即ち、クリップ１７は、係止凸部１７ｋにワイパアーム２の抜け方向の力が掛かると、弾性片部１７ｌが撓んで係止凸部１７ｋが前記抜け方向に移動しようとするがその力は規制部１７ｍにて受け止められて係止凸部１７ｋの移動が規制される。よって、ワイパアーム２とワイパブレード３との連結を強固なものとしながらも弾性片部１７ｌを撓み易くして係止凸部１７ｋを作業者が押下し易くすることができ、作業者による装着時や取外し時の作業性を向上させることができる。
Next, the characteristic effects of the above embodiment will be described below.
(1) The clip 17 extends in a direction (the orthogonal direction in the present embodiment) different from the attachment / detachment direction of the wiper arm 2 (longitudinal direction of the wiper blade 3), and has an elastic piece 17l provided with a locking projection 17k at the tip. Therefore, even if a force is applied in the direction in which the wiper arm 2 is pulled out, the bending of the elastic piece portion 17l does not occur in the direction of releasing the engagement between the locking projection 17k and the locking hole 4e. As a result, the connection between the wiper arm 2 and the wiper blade 3 is unlikely to be inadvertently disconnected, and the connection can be made stronger. Moreover, since the clip 17 has a restricting portion 17m that restricts the movement of the locking projection 17k in the direction in which the wiper arm 2 is pulled out, even if a force in the direction in which the wiper arm 2 is pulled out is applied to the locking projection 17k, FIG. As shown, the movement of the locking projection 17k in the same direction is restricted by the restricting portion 17m. That is, when a force in the direction in which the wiper arm 2 is pulled out is applied to the locking projection 17k, the clip 17 bends the elastic piece portion 17l and the locking projection 17k tries to move in the direction in which the clip 17 is moved. The movement of the locking projection 17k is restricted by being received at 17m. Accordingly, the elastic piece portion 17l can be easily bent and the operator can easily press the locking convex portion 17k while the connection between the wiper arm 2 and the wiper blade 3 is strengthened. Workability at the time of removal can be improved.
（２）弾性片部１７ｌは、その全体が、係止凸部１７ｋの前記着脱方向（ブレードラバー１１等の長手方向）の寸法よりも小さい寸法の狭部とされるため、係止凸部１７ｋの寸法を確保して例えば作業者が指等により押下し易い構成としながらも弾性片部１７ｌを撓み易くすることができる。 (2) Since the elastic piece portion 17l as a whole is a narrow portion having a dimension smaller than the dimension of the engaging projection 17k in the attaching / detaching direction (longitudinal direction of the blade rubber 11 or the like), the engaging convex portion 17k. The elastic piece portion 17l can be easily bent while being configured to be easy to be pressed by the operator with a finger or the like.
（３）係止凸部１７ｋは、クリップ１７の上壁１７ｂから上方に突出するように設けられ、弾性片部１７ｌは、その先端部が係止凸部１７ｋに接続され基端部がクリップ１７の側壁１７ａの上下方向中間部に接続されるため、例えば、弾性片部の基端部（撓み軸Ｚとなる接続部位）が上壁に設けられるような構成に比べて、弾性片部１７ｌの長さを容易に長く確保することができる。これにより、例えば、弾性片部１７ｌを容易に撓み易くすることができる。よって、作業者が係止凸部１７ｋをより押下し易くなり、作業者による装着時や取外し時の作業性をより向上させることができる。 (3) The locking convex portion 17k is provided so as to protrude upward from the upper wall 17b of the clip 17. The elastic piece portion 17l has a distal end connected to the locking convex portion 17k and a proximal end portion of the clip 17. For example, the elastic piece portion 17l has a base end portion (a connecting portion serving as the bending axis Z) provided on the upper wall. The length can be easily secured long. Thereby, for example, the elastic piece portion 17l can be easily bent. Therefore, it becomes easier for the operator to press down the locking projection 17k, and the workability at the time of attachment and removal by the operator can be further improved.
（４）弾性片部１７ｌは、クリップ１７の上壁１７ｂと側壁１７ａとの境界部分に折曲部１７ｎを有するため、弾性片部１７ｌの基端部の撓み軸Ｚで撓むだけでなくその折曲部１７ｎを軸中心としても撓み易くなり、作業者が係止凸部１７ｋをより押下し易くなり、作業者による装着時や取外し時の作業性をより向上させることができる。 (4) Since the elastic piece portion 17l has a bent portion 17n at the boundary portion between the upper wall 17b and the side wall 17a of the clip 17, not only is it bent at the bending axis Z of the base end portion of the elastic piece portion 17l, Even when the bent portion 17n is set as the axis center, it becomes easy to bend, and it becomes easier for the operator to press down the latching convex portion 17k, so that the workability at the time of attachment and removal by the operator can be further improved.
（５）係止凸部１７ｋ及び弾性片部１７ｌは、クリップ１７の上壁１７ｂ及び側壁１７ａの同一平面上にスリット１７ｐにて区画されて形成されるものであり、規制部１７ｍは、係止凸部１７ｋと対応した上壁１７ｂのスリット側端面であるため、スリット１７ｐの形状を設定するだけでそれら（弾性片部１７ｌや規制部１７ｍ）を容易に一体成形することかできる。又、弾性片部１７ｌ及び係止凸部１７ｋに対する規制部１７ｍ（スリット側端面）の位置関係（それらの間隔等）を容易に高精度に製造することができる。よって、安定した品質のクリップ１７を安価に製造することができる。なお、スリット１７ｐの幅は、係止凸部１７ｋの押下操作でスリット側端面と干渉しない程度に極力狭いことが好ましい。 (5) The locking projection 17k and the elastic piece 17l are formed by being partitioned by the slit 17p on the same plane of the upper wall 17b and the side wall 17a of the clip 17, and the restricting portion 17m Since it is the slit side end surface of the upper wall 17b corresponding to the convex part 17k, they (the elastic piece part 17l and the restricting part 17m) can be easily integrally formed only by setting the shape of the slit 17p. Further, the positional relationship (the interval between them) of the restricting portion 17m (slit side end surface) with respect to the elastic piece portion 17l and the locking convex portion 17k can be easily manufactured with high accuracy. Therefore, a stable quality clip 17 can be manufactured at low cost. The width of the slit 17p is preferably as narrow as possible so as not to interfere with the slit side end surface by the pressing operation of the locking projection 17k.
上記実施形態は、以下のように変更してもよい。
・上記実施形態では、規制部１７ｍによる係止凸部１７ｋの規制は、スリット側端面（規制部１７ｍ）に係止凸部１７ｋが上方から見て点接触して当接する構成としたが、これに限定されず、規制部１７ｍにて規制されたときの係止凸部１７ｋの姿勢を考慮して係止凸部１７ｋとスリット側端面（規制部１７ｍ）とが上方から見て線接触するように構成してもよい。
The above embodiment may be modified as follows.
In the above embodiment, the restriction of the locking projection 17k by the restriction portion 17m is configured such that the locking projection 17k contacts and contacts the slit side end surface (the restriction portion 17m) when viewed from above. The locking projection 17k and the slit-side end surface (regulation portion 17m) are in line contact when viewed from above in consideration of the posture of the locking projection 17k when regulated by the regulation portion 17m. You may comprise.
例えば、図１５に示すように、規制されたときの係止凸部１７ｋの姿勢（二点鎖線参照）を考慮して、スリット側端面に傾斜面を形成して規制部２１を構成してもよい。また、例えば、上方から見て線接触するように、係止凸部１７ｋ側に傾斜面を形成してもよい。また、勿論、スリット側端面と係止凸部１７ｋとに、上方から見て線接触するように互いに（小さい）傾斜面を形成してもよい。こうすることにより、規制時の応力が集中することを防止することができる。更に、前記傾斜面は、規制部にて規制されたときの係止凸部１７ｋの姿勢を考慮して係止凸部１７ｋとスリット側端面とが上下方向（板厚方向）にも線接触するように形成してもよい。こうすることにより、規制時の応力が集中することを更に防止することができる。 For example, as shown in FIG. 15, the restricting portion 21 may be configured by forming an inclined surface on the slit side end surface in consideration of the posture (see the two-dot chain line) of the locking convex portion 17 k when restricted. Good. Further, for example, an inclined surface may be formed on the locking projection 17k side so as to make a line contact when viewed from above. Of course, (small) inclined surfaces may be formed on the slit side end surface and the locking projection 17k so as to be in line contact with each other when viewed from above. By doing so, it is possible to prevent the stress during regulation from being concentrated. Further, in consideration of the posture of the locking convex portion 17k when the inclined surface is regulated by the regulating portion, the locking convex portion 17k and the slit side end surface are also in line contact in the vertical direction (plate thickness direction). You may form as follows. By doing so, it is possible to further prevent the stress during regulation from being concentrated.

For example, the narrow portion may be provided in a part of the elastic piece portion, or the narrow portion may not be provided, that is, the entire elastic portion having the same dimension as the dimension of the locking projection 17k in the attaching / detaching direction. It may be a single part.

However, the present invention is not limited to this. For example, the elastic piece portion and the restricting portion may be formed of pieces having independent independent ends.

As shown in the figure, a locking projection 17k may be connected to each tip of a pair of elastic pieces 22 extending from each side wall 17a. In this case, it is preferable that at least a part of the elastic piece portion 22 is thinner than the side wall 17a and the upper wall 17b to facilitate bending in the pressing direction.
・上記実施形態では、弾性片部１７ｌは、ワイパアーム２の着脱方向（ブレードラバー１１等の長手方向）の直交方向に延びるものとしたが、これに限定されず、例えば、直交方向から傾斜した方向に延びる弾性片部や、直交方向から傾斜した方向に延びる部分を有する弾性片部に変更してもよい。 In the above embodiment, the elastic piece portion 17l extends in a direction orthogonal to the attaching / detaching direction of the wiper arm 2 (longitudinal direction of the blade rubber 11, etc.), but is not limited to this, for example, a direction inclined from the orthogonal direction You may change into the elastic piece part which has a part extended in the direction inclined from the orthogonal | vertical direction and the elastic piece part which extends in the direction.
