Abstract
Description
特開平11-101058号公報に記載のウィンドレギュレータ装置によれば、窓ガラスの開閉位置が不感帯領域であるか否かを検知するためのカム部材が出力軸に連結された回転部材(ピニオンギヤ)の内周側に形成されている。このピニオンギヤは、特開平11-101058号公報の図2または図4からわかるようにハウジング内にて駆動ギヤに隣接して配置されるので、スペース上の制約が大きい。そのため、ピニオンギヤは小さい部材である。そして、このピニオンギヤの内周側に形成されるカムも小さい部材である。このような微小なカム部材を用いて窓ガラスの開閉位置が不感帯領域に属する位置であるか否かを検知する場合、わずかな組み付け誤差により検知精度が大きく悪化するおそれがある。また、検知精度の悪化を防止するために、カム部材の形状およびピニオンギヤの取り付け角度を厳密に管理した場合には、製造コストおよび組み付けコストが増大する。
本発明は、動力源と、前記動力源に連結され前記動力源が発生する動力により回転する出力軸と、前記出力軸の回転駆動力により車両の窓ガラスが開閉するように前記出力軸の回転駆動力を窓ガラスに伝達する駆動力伝達機構と、窓ガラスの開閉位置が予め定められる開閉位置領域である特定位置領域に属する位置であるか否かを検知する開閉位置検知手段とを備えるウィンドレギュレータ装置を開示する。前記開閉位置検知手段は、前記出力軸の回転駆動力により回転する回転部材と、窓ガラスの開閉位置が前記特定位置領域に属しない位置であるときに前記回転部材に係合せず、窓ガラスの開閉位置が前記特定位置領域に属する位置であるときに前記回転部材に係合し、係合時に前記回転部材を介して伝達される前記出力軸の回転駆動力により回転作動する作動レバーと、前記作動レバーの回転作動に基づいて切り換え作動する特定位置領域検知スイッチと、を備える。

次に、本発明の第2実施形態について説明する。本実施形態のウィンドレギュレータ装置は、位置検知ユニット以外の構成が上記第1実施形態にて説明した構成とほぼ同一である。したがって、第1実施形態と同一の構成については第1実施形態を参照することとしてその説明を省略し、以下、異なる構成を中心に説明する。
