Description

ウインドレギュレータ及び車両用ドアWindow regulators and vehicle doors
　本発明は、ウインドレギュレータ及び車両用ドアに関するものである。 The present invention relates to window regulators and vehicle doors.
　ワイヤ駆動式のウインドレギュレータとして、例えば、グリスが塗布されたワイヤを用いるウインドレギュレータがある（特許文献１参照）。このウインドレギュレータは、窓ガラス（ドアガラス）を支持するキャリアプレート（可動ブラケット）と、キャリアプレートを摺動案内するガイドレールと、一対のプーリに掛けて張設されたワイヤと、ワイヤを走行させることによりキャリアプレートをガイドレールに沿って移動させる駆動ドラムと、を含んでいる。このウインドレギュレータでは、ガイドレールの、ワイヤが接近する部分に線状溝を設け、この線状溝にグリスを付与しておくことで、ワイヤにグリスを塗布している。このようにグリスが塗布されたワイヤを用いることで、ワイヤがガイドレール等の他の部材に接触したときに生じる異音の発生や、ワイヤ及び当該他の部材の摩耗等を抑制することができるようになっている。 As a wire-driven window regulator, for example, there is a window regulator that uses a wire coated with grease (see Patent Document 1). This window regulator consists of a carrier plate (movable bracket) that supports the window glass (door glass), a guide rail that slides and guides the carrier plate, a wire that is stretched over a pair of pulleys, and a wire that runs. a drive drum for moving the carrier plate along the guide rails. In this window regulator, a linear groove is provided in a portion of the guide rail where the wire approaches, and grease is applied to the linear groove to apply grease to the wire. By using the wire coated with grease in this way, it is possible to suppress the generation of abnormal noise when the wire comes into contact with other members such as guide rails, and the abrasion of the wire and the other member. It's like

　しかし、ウインドレギュレータでは、ワイヤに塗布されたグリスが、窓ガラスの昇降動作に伴ってプーリ周りに蓄積する。そして、プーリ３１周りにグリスＧが蓄積した状態で、プーリの回転に伴うプーリからのワイヤの繰出しが行われると、蓄積されたグリスが引き出されて、プーリとプーリから繰り出されたワイヤとの間にグリスの膜が張る現象が生じる。プーリとワイヤとの間にグリスの膜が張った状態で、更にワイヤが繰り出されていくと、グリスの膜が薄くなっていき、最終的にグリスの膜が破れてグリスが糸状になる。この糸状になったグリスが、静電気等により窓ガラスに引き寄せられて、窓ガラスに付着してしまうという問題が生じた。 However, in the window regulator, the grease applied to the wire accumulates around the pulley as the window glass moves up and down. When the wire is fed out from the pulley as the pulley rotates in a state where the grease G is accumulated around the pulley 31, the accumulated grease is drawn out and the gap between the pulley and the wire fed out from the pulley is reduced.

This vehicle door is provided in an automobile (vehicle). On the other hand, a window regulator is an elevating device that is attached to a vehicle door and raises and lowers the window glass of the vehicle. In particular, the window regulator has a structure that suppresses the formation of a film of grease between the pulley and the wire drawn out from the pulley in a configuration using a wire coated with grease. In addition, hereinafter, the upward/downward direction, the upward direction, and the downward direction of the window glass are simply referred to as the upward/downward direction, the upward direction, and the downward direction. Further, hereinafter, description will be made by defining left and right, front and rear, and top and bottom as shown in each figure. In this embodiment, it is assumed that the vertical direction of the window regulator matches the vertical direction of the window regulator, and that the width direction of the vehicle matches the longitudinal direction of the window regulator.
（車両用ドアの構成）
　図１に示すように、車両用ドアＤは、ドア本体Ｄ１と、ドア本体Ｄ１に設けられたガラスガイドＤ１１、Ｄ１２に沿って昇降自在に支持された車両の窓ガラスＷと、ドア本体Ｄ１に取り付けられ、窓ガラスＷを昇降させるウインドレギュレータ１と、を備えている。本実施形態では、表面（車室外側）に撥水コーティングが施され、裏面（車室内側）に紫外線カットコーティングが施された窓ガラスＷを用いている。 (Structure of vehicle door)
As shown in FIG. 1, the vehicle door D includes a door body D1, a vehicle window glass W supported vertically along glass guides D11 and D12 provided in the door body D1, and a door body D1. and a window regulator 1 that is attached to move the window glass W up and down. In this embodiment, the window glass W is used, the front surface (outside of which the passenger compartment faces) is coated with a water-repellent coating, and the back surface (inner side of the passenger compartment) is treated with an ultraviolet-cut coating.
　ドア本体Ｄ１は、窓ガラスＷを格納する格納部Ｄ１３と、格納部Ｄ１３の上方に配設されたドアサッシＤ１４と、格納部Ｄ１３の上端部に配設され、窓ガラスＷに摺接するインナーウェザーストリップＤ１５及びアウターウェザーストリップＤ１６（図２参照）と、を有している。図２に示すように、格納部Ｄ１３は、車室内側のインナーパネルＤ１７と、車室外側のアウターパネルＤ１８と、を有しており、このインナーパネルＤ１７とアウターパネルＤ１８との間に、ドア内部空間が形成されている。 The door body D1 includes a storage portion D13 for storing the window glass W, a door sash D14 disposed above the storage portion D13, and an inner weather strip disposed at the upper end portion of the storage portion D13 and in sliding contact with the window glass W. D15 and an outer weather strip D16 (see FIG. 2). As shown in FIG. 2, the storage part D13 has an inner panel D17 on the interior side of the vehicle and an outer panel D18 on the exterior side of the vehicle. An internal space is formed.
　図２に示すように、インナーウェザーストリップＤ１５は、ドアサッシＤ１４の下部においてインナーパネルＤ１７の上端部に固定されており、車両前後方向に延在して直線状に設けられている。一方、アウターウェザーストリップＤ１６は、ドアサッシＤ１４の下部においてアウターパネルＤ１８の上端部に固定されており、車両前後方向に延在して直線状に設けられている。インナーウェザーストリップＤ１５は、ウインドレギュレータ１による窓ガラスＷの昇降動作に伴って窓ガラスＷの裏面に摺接し、アウターウェザーストリップＤ１６は、ウインドレギュレータ１による窓ガラスＷの昇降動作に伴って窓ガラスＷの表面に摺接する。これらにより、インナーウェザーストリップＤ１５及びアウターウェザーストリップＤ１６は、ドア内部空間への水等の浸入を抑止すると共に窓ガラスＷの汚れを除去する。これらのインナーウェザーストリップＤ１５やアウターウェザーストリップＤ１６による窓ガラスＷへの摺接が、窓ガラスＷに静電気が帯電する一因となっている。 As shown in FIG. 2, the inner weather strip D15 is fixed to the upper end of the inner panel D17 at the lower portion of the door sash D14, and extends linearly in the vehicle front-rear direction. On the other hand, the outer weather strip D16 is fixed to the upper end portion of the outer panel D18 at the lower portion of the door sash D14, and extends linearly in the vehicle front-rear direction. The inner weather strip D15 is brought into sliding contact with the rear surface of the window glass W as the window glass W is moved up and down by the window regulator 1, and the outer weather strip D16 is brought into contact with the back surface of the window glass W as the window glass W is moved up and down by the window regulator 1. slides on the surface of As a result, the inner weather strip D15 and the outer weather strip D16 prevent water from entering the interior space of the door and remove stains on the window glass W. As shown in FIG. The sliding contact of the inner weather strip D15 and the outer weather strip D16 with the window glass W is one of the reasons why the window glass W is charged with static electricity.
（ウインドレギュレータの構成）
　図１乃至図３Ｂに示すように、ウインドレギュレータ１は、上記ドア内部空間においてインナーパネルＤ１７に取り付けられており、昇降方向に沿って設けられたガイドレール２と、窓ガラスＷを支持すると共に、ガイドレール２に摺動自在に取り付けられたキャリアプレート３と、キャリアプレート３を牽引しガイドレール２に沿って昇降させる上昇側ワイヤ４（ワイヤ）及び下降側ワイヤ５と、ガイドレール２の下端部に配設され、上昇側ワイヤ４及び下降側ワイヤ５を駆動する駆動部６と、ガイドレール２の上端部に配設され、上昇側ワイヤ４を方向転換するプーリ３１を有するプーリアッセンブリ７と、ガイドレール２の長手方向略中央部に配設され、プーリ３１と駆動部６との間の上昇側ワイヤ４を支持するワイヤガイド８と、を備えている。すなわち、このウインドレギュレータ１は、ワイヤ４、５を用いてキャリアプレート３を昇降するワイヤ駆動式のウインドレギュレータであると共に、駆動部６がガイドレール２の下端部に配設された下端レール式のウインドレギュレータである。 (Configuration of window regulator)
As shown in FIGS. 1 to 3B, the window regulator 1 is attached to the inner panel D17 in the door interior space, and supports the guide rail 2 provided along the vertical direction and the window glass W, A carrier plate 3 slidably attached to a guide rail 2, an ascending wire 4 (wire) and a descending wire 5 for pulling the carrier plate 3 and moving it up and down along the guide rail 2, and the lower end of the guide rail 2. a drive unit 6 disposed in the upper end of the guide rail 2 for driving the ascending wire 4 and the descending wire 5; a pulley assembly 7 having a pulley 31 disposed at the upper end of the guide rail 2 and changing the direction of the ascending wire 4; A wire guide 8 is provided at substantially the center in the longitudinal direction of the guide rail 2 and supports the ascending wire 4 between the pulley 31 and the drive section 6 . That is, the window regulator 1 is a wire-driven window regulator for moving up and down a carrier plate 3 using wires 4 and 5, and a lower end rail type window regulator in which a driving portion 6 is disposed at the lower end portion of a guide rail 2. It's a window regulator.
　ガイドレール２は、長板状の金属板を所定の曲率で車幅方向に湾曲させて形成されており、ドア本体Ｄ１に対して車両前後方向の後方側に傾いて配置されている。そして、ガイドレール２は、昇降方向に沿って延在し、キャリアプレート３を昇降自在に支持している。 The guide rail 2 is formed by bending a long metal plate with a predetermined curvature in the vehicle width direction, and is arranged to be inclined rearward in the vehicle front-rear direction with respect to the door body D1. The guide rail 2 extends along the vertical direction and supports the carrier plate 3 so as to be vertically movable.
　図３Ａ及び図３Ｂに示すように、キャリアプレート３は、例えばポリアセタール等の樹脂によって形成された板状の部材であり、ガイドレール２上を摺動すると共に上昇側ワイヤ４及び下降側ワイヤ５の端部が取り付けられた本体部１１と、本体部１１の左右両端に形成された取付け孔１２、１２と、を有している。取付け孔１２、１２は、窓ガラスＷを保持するガラスホルダＷ１（図２参照）を取り付けるためのものである。すなわち、本実施形態では、キャリアプレート３は、ガラスホルダＷ１を介して、窓ガラスＷを支持している。 As shown in FIGS. 3A and 3B, the carrier plate 3 is a plate-like member made of resin such as polyacetal, and slides on the guide rails 2 while moving the ascending wire 4 and descending wire 5. It has a main body portion 11 to which end portions are attached, and mounting holes 12, 12 formed at both left and right ends of the main body portion 11. As shown in FIG. The mounting holes 12, 12 are for mounting a glass holder W1 (see FIG. 2) that holds the window glass W. As shown in FIG. That is, in this embodiment, the carrier plate 3 supports the windowpane W via the glass holder W1.
　上昇側ワイヤ４及び下降側ワイヤ５は、金属ワイヤで構成されており、表面にグリスＧ（図６Ａ乃至図６Ｄ参照）が塗布されている。上昇側ワイヤ４は、一端部が駆動部６のドラム２２（後述する）に連結されており、駆動部６から上方に繰り出されてプーリ３１に到り、プーリ３１によって下方に方向転換された後、他端部がキャリアプレート３に取り付けられている。一方、下降側ワイヤ５は、一端部が駆動部６のドラム２２に連結されており、駆動部６から上方に繰り出されて他端部がキャリアプレート３に取り付けられている。本実施形態では、プーリ３１からキャリアプレート３に到る上昇側ワイヤ４と、駆動部６からキャリアプレート３に到る下降側ワイヤ５とが、前方から見て（ドラム２２の軸方向から見て）、ガイドレール２と重なるように配設されている。そのため、上昇側ワイヤ４及び下降側ワイヤ５が、ガイドレール２に接触する構成となっている。これに対し、上昇側ワイヤ４及び下降側ワイヤ５の表面にグリスＧが塗布されていることで、ワイヤ４、５とガイドレール２との接触に伴う異音の発生や、ワイヤ４、５及びガイドレール２の摩耗を抑制することができる。なお、ワイヤ４、５の表面に加え、ガイドレール２の、ワイヤ４、５との接触部分にもグリスＧが塗布されていることが好ましい。 The ascending wire 4 and the descending wire 5 are made of metal wire, and the surfaces thereof are coated with grease G (see FIGS. 6A to 6D). One end of the ascending wire 4 is connected to a drum 22 (described later) of the drive unit 6, and is let out upward from the drive unit 6 to reach the pulley 31, and after being turned downward by the pulley 31 , the other end is attached to the carrier plate 3 . On the other hand, the descending wire 5 has one end connected to the drum 22 of the driving section 6 , extends upward from the driving section 6 , and has the other end attached to the carrier plate 3 . In the present embodiment, the ascending wire 4 extending from the pulley 31 to the carrier plate 3 and the descending wire 5 extending from the drive unit 6 to the carrier plate 3 are arranged in the same position as viewed from the front (as seen from the axial direction of the drum 22). ), which are arranged so as to overlap the guide rails 2 . Therefore, the ascending wire 4 and the descending wire 5 are configured to contact the guide rail 2 . On the other hand, since the grease G is applied to the surfaces of the ascending wire 4 and the descending wire 5, abnormal noise is generated due to the contact between the wires 4, 5 and the guide rail 2, and the wires 4, 5 and Wear of the guide rail 2 can be suppressed. In addition to the surfaces of the wires 4 and 5, it is preferable that the grease G is applied to the contact portions of the guide rail 2 with the wires 4 and 5 as well.
　駆動部６は、正逆回転駆動可能な減速機付きのモータ２１と、上昇側ワイヤ４及び下降側ワイヤ５の端部が連結され、モータ２１の駆動によって回転することにより上昇側ワイヤ４及び下降側ワイヤ５の巻取り及び繰出しを行う円筒状のドラム２２と、ガイドレール２の下端部が嵌合すると共にドラム２２を回転自在に収容するドラムハウジング２３と、ドラムハウジング２３に取り付けられ、モータ２１を保持するモーターハウジング２４と、を有している。 The drive unit 6 is connected to a motor 21 having a speed reducer capable of forward and reverse rotation, and ends of the ascending wire 4 and the descending wire 5 are connected to each other. A cylindrical drum 22 for winding and feeding the side wire 5, a drum housing 23 into which the lower end of the guide rail 2 is fitted and housing the drum 22 rotatably, and a motor 21 attached to the drum housing 23. and a motor housing 24 that holds the .
　モータ２１を正転駆動すると、ドラム２２が正転し、これに伴って、下降側ワイヤ５が繰り出されつつ上昇側ワイヤ４が巻き取られる。これによって、キャリアプレート３が上昇側ワイヤ４に引っ張られ上昇方向に移動する。これにより、キャリアプレート３に取り付けられた窓ガラスＷが上昇する。一方、モータ２１を逆転駆動すると、ドラム２２が逆転し、これに伴って、上昇側ワイヤ４が繰り出されつつ下降側ワイヤ５が巻き取られる。これによって、キャリアプレート３が下降側ワイヤ５に引っ張られ下降方向に移動する。これにより、キャリアプレート３に取り付けられた窓ガラスＷが下降する。 When the motor 21 is driven to rotate forward, the drum 22 rotates forward, and along with this, the ascending wire 4 is wound while the descending wire 5 is let out. As a result, the carrier plate 3 is pulled by the ascending wire 4 and moved in the ascending direction. As a result, the window glass W attached to the carrier plate 3 is lifted. On the other hand, when the motor 21 is reversely driven, the drum 22 is reversed, whereby the ascending wire 4 is let out and the descending wire 5 is wound. As a result, the carrier plate 3 is pulled by the lowering wire 5 and moves in the lowering direction. As a result, the window glass W attached to the carrier plate 3 is lowered.
（プーリアッセンブリの構成）
　次に図４Ａ乃至図５Ｄを参照して、プーリアッセンブリ７について説明する。図４Ａ乃至図４Ｃに示すように、プーリアッセンブリ７は、上昇側ワイヤ４が巻き掛けられ、上昇側ワイヤ４を方向転換するプーリ３１と、ガイドレール２の上端部に固定された金属製のプーリブラケット３２と、プーリブラケット３２に固定されると共に、プーリ３１を回転自在に支持するプーリシャフト３３と、プーリ３１とプーリブラケット３２との間に取り付けられたグリス阻止部材３４と、を有している。 (Configuration of pulley assembly)

As shown in FIGS. 4A to 4C , the pulley assembly 7 includes a pulley 31 around which the ascending wire 4 is wound and for changing the direction of the ascending wire 4 , and a metal pulley fixed to the upper end of the guide rail 2 . It has a bracket 32, a pulley shaft 33 fixed to the pulley bracket 32 and rotatably supporting the pulley 31, and a grease prevention member 34 attached between the pulley 31 and the pulley bracket 32. .
　プーリ３１は、上昇側ワイヤ４が巻き掛けられるガイド溝３１ａが周設されており、プーリシャフト３３に回転自在に支持されると共に、駆動部６から上方に繰り出されてきた上昇側ワイヤ４を、下方に且つキャリアプレート３に向かって方向転換する。そのため、プーリ３１は、上昇側ワイヤ４を、ガイド溝３１ａの右部から下方に且つキャリアプレート３に向かって繰り出すと共に、ガイド溝３１ａの左部から下方に且つ駆動部６（ドラム２２）に向かって繰り出すと言える。なお、プーリ３１からキャリアプレート３に（一側に）繰り出された上昇側ワイヤ４を、符号４ａとし、プーリ３１から駆動部６に（他側に）繰り出された上昇側ワイヤ４を、符号４ｂとする。 The pulley 31 has a guide groove 31a around which the ascending wire 4 is wound, and is rotatably supported by the pulley shaft 33. Turn downwards and towards the carrier plate 3 . Therefore, the pulley 31 feeds the ascending wire 4 downward from the right portion of the guide groove 31a toward the carrier plate 3, and downward from the left portion of the guide groove 31a toward the driving portion 6 (drum 22). It can be said that The ascending wire 4 drawn out (to one side) from the pulley 31 to the carrier plate 3 is designated as 4a, and the ascending wire 4 drawn out (to the other side) from the pulley 31 to the drive section 6 is designated as 4b. and
（グリス阻止部材の構成）
　図５Ａ乃至図５Ｄに示すように、グリス阻止部材３４は、樹脂製の部材で構成されており、プーリ３１とプーリブラケット３２との間に取り付けるための円形取付け部４１と、円形取付け部４１の下部から右斜め下に延びる右腕部４２と、右腕部４２の先端から前方に立ち上がる右阻止リブ４３（第１の阻止部）と、円形取付け部４１の下部から左斜め下に延びる左腕部４４と、左腕部４４の先端から前方に立ち上がる左阻止リブ４５（第２の阻止部）と、を一体として有している。 (Structure of Grease Blocking Member)

A right arm portion 42 extending obliquely downward to the right from the lower portion, a right blocking rib 43 (first blocking portion) rising forward from the tip of the right arm portion 42, and a left arm portion 44 extending obliquely downward left from the lower portion of the circular mounting portion 41. , and a left blocking rib 45 (second blocking portion) that rises forward from the tip of the left arm portion 44 .
　円形取付け部４１には、プーリシャフト３３を挿通する挿通孔５１と、円形取付け部４１の回止めを行う回止め突起５２と、を有している。回止め突起５２が、プーリブラケット３２に形成された係合孔３２ａと係合することで、円形取付け部４１が、プーリ３１に連れ回りするのが阻止され、プーリ３１とプーリブラケット３２との間において、プーリシャフト３３で位置決めされ且つ回転不能に取り付けられた状態となっている。 The circular mounting portion 41 has an insertion hole 51 through which the pulley shaft 33 is inserted, and a detent projection 52 that prevents the circular mounting portion 41 from rotating. By engaging the anti-rotation protrusion 52 with the engagement hole 32 a formed in the pulley bracket 32 , the circular mounting portion 41 is prevented from rotating with the pulley 31 , and the gap between the pulley 31 and the pulley bracket 32 is prevented. , it is positioned by the pulley shaft 33 and attached so as not to rotate.
　右阻止リブ４３は、プーリ３１とプーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａとの間に配設されており、プーリ３１の径方向を厚さ方向とし、プーリ３１の周方向に延在する正面視円弧状のリブで構成されている。また、右阻止リブ４３の前後方向の高さは、プーリ３１のガイド溝３１ａを超える高さとなっている。また、右阻止リブ４３の延在方向端部は、プーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａに近接している。プーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａは、窓ガラスＷの昇降動作に伴って、右阻止リブ４３の当該端部に摺接する構成となっている。なお、右阻止リブ４３の上昇側ワイヤ４ａが接触する側の角部は、Ｒ面取りされていることが好ましい。また、本実施形態においては、右阻止リブ４３の延在方向端部が上昇側ワイヤ４ａに接触する構成であったが、右阻止リブ４３の延在方向端部が上昇側ワイヤ４ａに近接する構成であれば、右阻止リブ４３の端部が上昇側ワイヤ４ａに接触しない（非接触である）構成であっても良い。 The right blocking rib 43 is disposed between the pulley 31 and the ascending wire 4a fed from the pulley 31 to the carrier plate 3. It is composed of elongated arc-shaped ribs when viewed from the front. Further, the height of the right blocking rib 43 in the front-rear direction exceeds the guide groove 31 a of the pulley 31 . Further, the extending direction end of the right blocking rib 43 is close to the ascending wire 4 a that is let out from the pulley 31 to the carrier plate 3 . The ascending wire 4a drawn out from the pulley 31 to the carrier plate 3 is configured to slidably contact the end portion of the right blocking rib 43 as the window glass W moves up and down. The corner portion of the right blocking rib 43 on the side that the ascending wire 4a contacts is preferably rounded. Further, in the present embodiment, the extending direction end of the right blocking rib 43 is in contact with the ascending wire 4a, but the extending direction end of the right blocking rib 43 approaches the ascending wire 4a. As long as it is configured, the end portion of the right blocking rib 43 may be configured so as not to contact (non-contact) the ascending wire 4a.
　そして、右阻止リブ４３は、プーリ３１と、プーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａとの間にグリスＧの膜が張るのを阻止する。具体的には、図６Ａに示すように、窓ガラスＷの昇降動作の繰返しによって、上昇側ワイヤ４に塗布されたグリスＧが、プーリ３１周り（具体的にはプーリ３１から上昇側ワイヤ４ａを繰り出す繰出し位置周り）に蓄積する。プーリ３１周りにグリスＧが蓄積した状態で、プーリ３１の回転に伴って、上昇側ワイヤ４がプーリ３１からキャリアプレート３に繰り出されると、図６Ｂの想像線で示すように、プーリ３１周りに蓄積したグリスＧが引き出されて、グリスＧの膜が、プーリ３１とプーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａとの間に張ろうとするところ、同図に示すように、右阻止リブ４３は、プーリ３１とプーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａとの間にグリスＧの膜が張るのを阻止する。これにより、プーリ３１と、プーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ａとの間にグリスＧの膜が張るのを抑制することができる。なお、図６Ｂでは、右阻止リブ４３が、引き出されてくるグリスＧを留めるものを図示しているが、右阻止リブ４３が、引き出されてくるグリスＧの膜を切断して、グリスＧの膜が、図６Ｂの想像線の位置に張らないようにすることが好ましい。そのため、右阻止リブ４３は、引き出されてくるグリスＧの膜に対向する角部を有することが好ましい。 The right blocking rib 43 prevents the grease G from forming a film between the pulley 31 and the ascending wire 4 a fed from the pulley 31 to the carrier plate 3 . Specifically, as shown in FIG. 6A, the grease G applied to the ascending wire 4 spreads around the pulley 31 (specifically, from the pulley 31 to the ascending wire 4a) as the window glass W is repeatedly moved up and down. around the payout position). When the rising wire 4 is let out from the pulley 31 to the carrier plate 3 with the rotation of the pulley 31 in a state where the grease G is accumulated around the pulley 31, as shown by the imaginary line in FIG. When the accumulated grease G is pulled out and the film of grease G is about to be stretched between the pulley 31 and the ascending wire 4a fed out from the pulley 31 to the carrier plate 3, as shown in FIG. The rib 43 prevents a film of grease G from forming between the pulley 31 and the ascending wire 4 a fed from the pulley 31 to the carrier plate 3 . As a result, it is possible to suppress the formation of a film of grease G between the pulley 31 and the ascending wire 4 a fed from the pulley 31 to the carrier plate 3 . FIG. 6B shows that the right blocking rib 43 retains the grease G that is being pulled out, but the right blocking rib 43 cuts the film of the grease G that is being pulled out to prevent the grease G from It is preferred that the membrane is not stretched at the phantom line position in FIG. 6B. Therefore, it is preferable that the right blocking rib 43 has a corner facing the film of the grease G that is drawn out.
　左阻止リブ４５は、プーリ３１とプーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂとの間に配設されており、プーリ３１の径方向を厚さ方向とし、プーリ３１の周方向に延在する正面視円弧状のリブで構成されている。また、左阻止リブ４５の前後方向の高さは、プーリ３１のガイド溝３１ａを超える高さとなっている。また、左阻止リブ４５の延在方向端部は、プーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂに近接している。プーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂは、窓ガラスＷの昇降動作に伴って、左阻止リブ４５の当該端部に摺接する構成となっている。なお、左阻止リブ４５の上昇側ワイヤ４ｂが接触する側の角部は、Ｒ面取りされていることが好ましい。また、本実施形態においては、左阻止リブ４５の延在方向端部が上昇側ワイヤ４ｂに接触する構成であったが、左阻止リブ４５の延在方向端部が上昇側ワイヤ４ｂに近接する構成であれば、左阻止リブ４５の端部が上昇側ワイヤ４ｂに接触しない（非接触である）構成であっても良い。 The left blocking rib 45 is disposed between the pulley 31 and the ascending wire 4b fed out from the pulley 31 to the driving portion 6, and the radial direction of the pulley 31 is the thickness direction, and the circumferential direction of the pulley 31 is the thickness direction. It is composed of elongated arc-shaped ribs when viewed from the front. Further, the height of the left blocking rib 45 in the front-rear direction exceeds the guide groove 31 a of the pulley 31 . In addition, the extending direction end of the left blocking rib 45 is close to the ascending wire 4 b that is let out from the pulley 31 to the driving portion 6 . The ascending wire 4b drawn out from the pulley 31 to the driving portion 6 is configured to slidably contact the end portion of the left blocking rib 45 as the window glass W moves up and down. The corner portion of the left blocking rib 45 on the side with which the ascending wire 4b contacts is preferably rounded. Further, in the present embodiment, the extending direction end of the left blocking rib 45 contacts the ascending wire 4b, but the extending direction end of the left blocking rib 45 approaches the ascending wire 4b. As long as it is configured, the end of the left blocking rib 45 may be configured so as not to contact (non-contact) the ascending wire 4b.
　そして、左阻止リブ４５は、プーリ３１と、プーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂとの間にグリスＧの膜が張るのを阻止する。具体的には、図６Ｃに示すように、窓ガラスＷの昇降動作の繰返しによって、上昇側ワイヤ４に塗布されたグリスＧが、プーリ３１周り（具体的にはプーリ３１から上昇側ワイヤ４ｂを繰り出す繰出し位置周り）に蓄積する。プーリ３１周りにグリスＧが蓄積した状態で、プーリ３１の回転に伴って、上昇側ワイヤ４がプーリ３１から駆動部６に繰り出されると、図６Ｄの想像線で示すように、プーリ３１周りに蓄積したグリスＧが引き出されて、グリスＧの膜が、プーリ３１とプーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂとの間に張ろうとするところ、同図に示すように、左阻止リブ４５は、プーリ３１とプーリ３１からキャリアプレート３に繰り出された上昇側ワイヤ４ｂとの間にグリスＧの膜が張るのを阻止する。これにより、プーリ３１と、プーリ３１から駆動部６に繰り出された上昇側ワイヤ４ｂとの間にグリスＧの膜が張るのを抑制することができる。なお、図６Ｄでは、左阻止リブ４５が、引き出されてくるグリスＧを留めるものを図示しているが、左阻止リブ４５が、引き出されてくるグリスＧの膜を切断して、グリスＧの膜が、図６Ｄの想像線の位置に張らないようにすることが好ましい。そのため、左阻止リブ４５は、引き出されてくるグリスＧの膜に対向する角部を有することが好ましい。 The left blocking rib 45 prevents a film of grease G from forming between the pulley 31 and the ascending wire 4b fed out from the pulley 31 to the driving portion 6 . Specifically, as shown in FIG. 6C, the grease G applied to the ascending wire 4 spreads around the pulley 31 (specifically, from the pulley 31 to the ascending wire 4b) as the window glass W is repeatedly moved up and down. around the payout position). With the grease G accumulated around the pulley 31, when the ascending wire 4 is let out from the pulley 31 to the drive unit 6 as the pulley 31 rotates, it will rotate around the pulley 31 as shown by the imaginary line in FIG. 6D. When the accumulated grease G is pulled out and the film of grease G is about to be stretched between the pulley 31 and the ascending wire 4b fed out from the pulley 31 to the drive unit 6, the left blockage occurs as shown in the figure. The ribs 45 prevent the grease G from forming a film between the pulley 31 and the ascending wire 4b fed from the pulley 31 to the carrier plate 3 . As a result, it is possible to suppress the formation of a film of grease G between the pulley 31 and the ascending wire 4b fed from the pulley 31 to the drive unit 6 . Although FIG. 6D shows that the left blocking rib 45 retains the grease G that is being pulled out, the left blocking rib 45 cuts the film of the grease G that is being pulled out so that the grease G can be removed. It is preferred that the membrane is not stretched to the phantom line position in FIG. 6D. Therefore, it is preferable that the left blocking rib 45 has a corner facing the film of the grease G that is drawn out.
（実施形態の作用及び効果）
　以上のような構成によれば、阻止リブ４３、４５を備えたことで、プーリ３１とプーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間にグリスＧの膜が張るのを抑制することができる。 (Action and effect of embodiment)
According to the above configuration, by providing the blocking ribs 43 and 45, it is possible to suppress the formation of a film of the grease G between the pulley 31 and the ascending wires 4a and 4b fed out from the pulley 31. can be done.
　すなわち、グリスＧが塗布されているワイヤ４、５を用いるウインドレギュレータ１では、図７Ａに示すように、窓ガラスＷの昇降動作の繰返しによって、上昇側ワイヤ４に塗布されたグリスＧが、プーリ３１周り（特に上昇側ワイヤ４の繰出し位置周り）に蓄積する。そして、阻止リブ４３、４５がない構成では、プーリ３１周りにグリスＧが蓄積した状態で、プーリ３１の回転に伴ってプーリ３１から上昇側ワイヤ４を繰り出すと、図７Ｂに示すように、プーリ３１周りからグリスＧが引き出されて、グリスＧの膜が、プーリ３１とプーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間に張る現象が生じる。プーリ３１とプーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間にグリスＧの膜が張った状態で、更に上昇側ワイヤ４ａ、４ｂが繰り出されていくと、グリスＧの膜が薄くなっていき、最終的にグリスＧの膜が破れてグリスＧが糸状になる。この糸状になったグリスＧが、図７Ｃに示すように、静電気等によって窓ガラスＷに引き寄せられ、窓ガラスＷに付着してしまうという問題があった。特に、本実施形態のように、窓ガラスＷの表面（車室外側）に撥水コーティングが施され、窓ガラスＷの裏面（車室内側）に紫外線カットコーティングが施されている場合には、窓ガラスＷ上に静電気が帯電しやすいため、このような問題が生じやすい。
　これに対し、上記実施形態に構成によれば、阻止リブ４３、４５を備えたことで、プーリ３１周りに蓄積されたグリスＧが引き出されて、グリスＧの膜が、プーリ３１とプーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間に張ることを阻止することができ、プーリ３１とプーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間にグリスＧの膜が張るのを抑制することができる。これにより、グリスＧが糸状になり、窓ガラスＷに付着してしまうのを防止することができる。 That is, in the window regulator 1 using the wires 4 and 5 to which the grease G is applied, as shown in FIG. 7A, the grease G applied to the ascending wire 4 is applied to the pulley as the window glass W is repeatedly moved up and down. 31 (especially around the feeding position of the ascending wire 4). Then, in a configuration without the blocking ribs 43 and 45, when the rising wire 4 is let out from the pulley 31 as the pulley 31 rotates in a state where the grease G is accumulated around the pulley 31, as shown in FIG. The grease G is pulled out from around the pulley 31, and a film of the grease G stretches between the pulley 31 and the ascending wires 4a and 4b fed out from the pulley 31 occurs. With the grease G film stretched between the pulley 31 and the ascending wires 4a and 4b drawn out from the pulley 31, when the ascending wires 4a and 4b are further drawn out, the grease G film becomes thinner. Eventually, the film of the grease G breaks and the grease G becomes thread-like. As shown in FIG. 7C, there is a problem that the thread-like grease G is attracted to the window glass W due to static electricity or the like and adheres to the window glass W. As shown in FIG. In particular, as in the present embodiment, when the surface of the window glass W (outside the vehicle) is coated with a water-repellent coating and the back surface of the window glass W (inside the vehicle) is coated with an ultraviolet cut coating, Since the window glass W is easily charged with static electricity, such a problem is likely to occur.
On the other hand, according to the configuration of the above embodiment, since the blocking ribs 43 and 45 are provided, the grease G accumulated around the pulley 31 is drawn out, and the film of the grease G is removed from the pulley 31 and the pulley 31. It is possible to prevent tension between the drawn-out ascending wires 4a and 4b, and suppress the stretching of a film of grease G between the pulley 31 and the ascending- side wires 4a and 4b let out from the pulley 31. can do. Thereby, it is possible to prevent the grease G from becoming thread-like and adhering to the window glass W.
　また、上記実施形態の構成によれば、阻止リブ４３、４５の一部が、プーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂに近接していることで、阻止リブ４３、４５と、プーリ３１から繰り出された上昇側ワイヤ４ａ、４ｂとの間に、グリスＧの膜が張るのを抑制することができる。 Further, according to the configuration of the above embodiment, part of the blocking ribs 43 and 45 are close to the ascending wires 4a and 4b fed out from the pulley 31, so that the blocking ribs 43 and 45 and the pulley 31 It is possible to suppress the film of the grease G from being stretched between the ascending wires 4a and 4b fed out from.
