Abstract
Description
これによれば、前記歯付きベルトは、前記駆動側案内部及び前記レール側案内部のそれぞれにおいて、各々の前記対向面に前記ラック歯が移動することが規制される。これにより、前記駆動側案内部及び前記レール側案内部のそれぞれにおいて、前記ラック歯及び前記対向面の間に所要の隙間を確保することができる。従って、例えば製造ばらつきや組付誤差等で、前記駆動側案内部及び前記レール側案内部の境界位置で各々の前記対向面間に段差が生じても、前記隙間の範囲で当該段差を吸収することで、前記歯付きベルトの移動時の前記ラック歯の干渉を抑制することができ、これに起因する異音の発生を抑制することができる。
サンルーフ装置10は、図1に示されるように、車両のルーフ11に形成される略四角形の開口部12に設置される。開口部12は、車両左右両側において、車両前記方向(ルーフ11の前後方向)に延びる左右縁部を有する。サンルーフ装置10は、開口部12の左右縁部に沿って延びるようにルーフ11に固定された右側ガイドレール13a及び左側ガイドレール13bを備える。両ガイドレール13a,13bは、例えばアルミニウム合金を押出成形することで形成される。
(1)各ベルト24,25の一対の摺動部29が対応する駆動側嵌合部31a,35a,34aもしくはレール側嵌合部20a,20bに摺動可能に嵌合することで、ガイド溝16,21a~21dの対向面42a,32aに向かって各ベルト24,25のラック歯26が移動することが規制される。これにより、両ベルト24,25の移動中においても、ラック歯26と対向面42a,32aとの間に常に隙間を確保することができる。従って、例えば側壁42,32の成形時に対向面42a,32aに段差(例えば金型の継ぎ目など)が生じたり、対向面42a,32aに切り欠きを設けたりしても、両ベルト24,25の移動時にラック歯26がこれら段差等と干渉することを抑制することができ、これに起因する異音及び振動の発生を抑制することができる。また、両ベルト24,25が対応する第1~第4のガイド溝21a~21dから対応するレール側ガイド溝16に進入する際、若しくは対応するレール側ガイド溝16から対応する第1~第4のガイド溝21a~21dに進入する際、レール側ガイド溝16又は第1~第4のガイド溝21a~21dの端部で側壁42,32とラック歯26とが干渉することを抑制することができ、これに起因する異音及び振動の発生を抑制することができる。
上記実施形態においては、ベルト部27は、その幅方向両側部に摺動部29を有しているが、摺動部29の位置及び形状はこれに限定されない。例えば、図9に示されるように、第1のベルト24の背面28に第1のベルト24の長手方向に亘って延びる断面略T字状の摺動部50を形成してもよい。この場合には、各ガイド溝21a~21dの経路に沿って第1側壁32に前記摺動部50に嵌合する断面略T字の嵌合溝38を形成する。また、図10に示されるように、第1のベルト24の背面28に第1のベルト24の長手方向に亘って延びる断面略台形状の摺動部51を形成してもよい。この場合には、各ガイド溝21a~21dの経路に沿って第1側壁32に前記摺動部29に嵌合する断面略台形状の嵌合溝52を形成する。これらの構成により、第1のベルト24の上下及び水平方向への移動が規制されつつ、第1のベルト24の長手方向(図9及び図10紙面方向)への移動が可能となる。なお、以上のように第1のベルト24の背面28に摺動部29が設けられる構成とした場合には、第1のベルト24の円滑な受け渡しのために、第1のベルト24の背面28に対向する傾斜部37を省略する必要がある。
上記実施形態において、駆動歯車23の位置で車両幅方向両側に2分割されたフロントハウジングを採用してもよい。
上記実施形態においては、ガイド溝21a~21dにベルト24,25を保持していたが、これに限らず、ベルト24,25をケーシングパイプ内に保持するタイプであっても本発明を適用可能である。すなわち、ケーシングパイプの内部に嵌合部31a,35aを設けたり、ガイドレール13a,13bに傾斜部37を設けたりすることで、ベルト24,25及びケーシングパイプ間の干渉による異音等を低減することができる。
