　〔実施形態１〕
　図１は、実施形態１の車両の駆動装置を示す概略図である。
　実施形態１の車両は、シリーズ方式とパラレル方式とを切り替えて走行可能なハイブリッド車両である。駆動装置は、エンジン（内燃機関）１、発電用モータ（第１回転電機）２、走行用モータ（第２回転電機）３、ギヤボックス４、ドライブシャフト（車両駆動軸）５および駆動輪６を備える。ギヤボックス４は、ケーシングの内部に複数のギヤ列（発電用モータギヤ列７、走行用モータ減速機構９、デファレンシャル（第２ギヤ列）１０およびエンジン用変速機構１１）を収容する。
　エンジン１のクランク軸（出力軸）１ａは、ギヤボックス４に収容された入力軸１ｂと一体に設けられている。入力軸１ｂは、発電用モータギヤ列７を介して発電用モータ２のモータ軸２ａと接続されている。発電用モータギヤ列（第１ギヤ列）７は、互いに噛み合う２つのギヤ７ａ，７ｂを有する。駆動ギヤ７ａは、入力軸１ｂに固定された駆動ギヤ（第１ギヤ）１３ａ１と噛み合う。被動ギヤ７ｂは、モータ軸２ａに固定されている。
　走行用モータ３のモータ軸３ａは、ギヤボックス４に収容されたモータ走行用クラッチ８を介して走行用モータ減速機構９の駆動ギヤ９ａ１と連結可能である。モータ走行用クラッチ８は、回転同期機構を持たないことで、回転同期状態での噛み合いストロークにより締結されるドグクラッチである。モータ走行用クラッチ８（のスリーブ）が左側締結位置（Ｌｅｆｔ）のとき、モータ軸３ａと走行用モータ減速機構９の駆動ギヤ９ａ１とが連結され、モータ走行用クラッチ８（のスリーブ）が右側解放位置（ｒｉｇｈｔ）のとき、モータ軸３ａと駆動ギヤ９ａ１との連結が切り離される。
　走行用モータ減速機構９は、走行用モータギヤ列９ａおよび走行用モータ最終減速ギヤ９ｂを有する。走行用モータギヤ列９ａは、互いに噛み合う２つのギヤ９ａ１，９ａ２を有する。駆動ギヤ９ａ１は、モータ軸３ａ上に回転可能に支持された遊転歯車である。被動ギヤ９ａ２は、回転軸９ｃに固定されている。回転軸９ｃには、走行用モータ最終減速ギヤ９ｂが固定されている。走行用モータ最終減速ギヤ９ｂは、デファレンシャル１０のリングギヤ１０ａと噛み合う。デファレンシャル１０は、リングギヤ１０ａの他、内部に作動機構部（不図示）を有するデフケース１０ｂを備える。作動機構部の左右サイドギヤは、左右のドライブシャフト５と連結されている。左右のドライブシャフト５は、駆動輪６と連結されている。
　エンジン用変速機構１１は、ローギヤ段とハイギヤ段とを切り替え可能な自動変速機であって、ハイギヤ段用ギヤ列１２、ローギヤ段用ギヤ列１３、ハイ用クラッチ（第２クラッチ）１４およびロー用クラッチ（第１クラッチ）１５を有する。
　ハイギヤ段用ギヤ列１２は、互いに噛み合う２つのギヤ１２ａ１，１２ａ２を有する。駆動ギヤ（第３ギヤ）１２ａ１は、入力軸１ｂ上に回転可能に支持された遊転歯車である。駆動ギヤ１２ａ１は、ハイ用クラッチ１４を介して入力軸１ｂと連結可能である。被動ギヤ（第４ギヤ）１２ａ２は、カウンタ軸１２ｂに固定され、デファレンシャル１０のリングギヤ（減速大歯車）１０ａと噛み合う。つまり、被動ギヤ１２ａ２は、最終減速装置の減速小歯車（エンジン最終減速ギヤ）を兼ねる。
　ローギヤ段用ギヤ列１３は、互いに噛み合う２つのギヤ１３ａ１，１３ａ２を有する。被動ギヤ（第２ギヤ）１３ａ２は、カウンタ軸１２ｂ上に回転可能に支持された遊転歯車である。被動ギヤ１３ａ２は、ロー用クラッチ１５を介してカウンタ軸１２ｂと連結可能である。ローギヤ段用ギヤ列１３は、ハイギヤ段用ギヤ列１２よりも変速比が大きい。
　ハイ用クラッチ１４は、回転同期機構を持たないことで、回転同期状態での噛み合いストロークにより締結されるドグクラッチである。ハイ用クラッチ１４（のスリーブ）が右側締結位置（Ｒｉｇｈｔ）のとき、駆動ギヤ１２ａ１と入力軸１ｂとが連結され、ハイ用クラッチ１４（のスリーブ）が左側解放位置（Ｌｅｆｔ）のとき、駆動ギヤ１２ａ１と入力軸１ｂとの連結が切り離される。駆動ギヤ１２ａ１と入力軸１ｂとの連結により、エンジン用変速機構１１はハイギヤ段となり、エンジン１から駆動輪６に至る動力伝達経路は、図１に一点鎖線で示す経路をとる。
　ロー用クラッチ１５は、回転同期機構を持たないことで、回転同期状態での噛み合いストロークにより締結されるドグクラッチである。ロー用クラッチ１５（のスリーブ）が左側締結位置（Ｌｅｆｔ）のとき、被動ギヤ１３ａ２とカウンタ軸１２ｂとが連結され、第２クラッチ（のスリーブ）が右側解放位置（Ｒｉｇｈｔ）のとき、被動ギヤ１３ａ２とカウンタ軸１２ｂとの連結が切り離される。被動ギヤ１３ａ２とカウンタ軸１２ｂとの連結により、エンジン用変速機構１１はローギヤ段となり、エンジン１から駆動輪６に至る動力伝達経路は、図１の破線で示す経路をとる。
　ここで、クランク軸１ａの軸線方向と直交する方向に延びる３つの平面Ｐ１，Ｐ２，Ｐ３を設定する。各平面Ｐ１，Ｐ２，Ｐ３は、互いに平行であり、第１平面Ｐ１は左側、第２平面Ｐ２は右側に位置し、第３平面Ｐ３は第１平面Ｐ１と第２平面Ｐ２との間に位置する。
　第１平面Ｐ１上には、発電用モータギヤ列７、ローギヤ段用ギヤ列１３および走行用モータ減速機構９が配置されている。また、第２平面Ｐ２上には、ハイギヤ段用ギヤ列１２およびデファレンシャル１０が配置されている。第３平面Ｐ３上には、ハイ用クラッチ１４、ロー用クラッチ１５およびモータ走行用クラッチ８（の各スリーブ）が配置されている。
　実施形態１の車両は、モータ走行用クラッチ８を締結する一方、ハイ用クラッチ１４およびロー用クラッチ１５を共に解放することにより、走行用の動力源として走行用モータ３のみを用い、エンジン１を発電用の動力源として使用するシリーズハイブリッドモードによる走行を行う。また、モータ走行用クラッチ８を解放する一方、ハイ用クラッチ１４とロー用クラッチ１５の一方を選択的に締結することにより、走行用の動力源としてエンジン１のみを用いるエンジン直結モードによる走行を行う。エンジン直結モードでは、エンジン用変速機構１１により、ローギヤ段とハイギヤ段とを切り替え可能である。
　なお、実施形態１の車両は、ハイ用クラッチ１４とロー用クラッチ１５の一方を締結した状態で、モータ走行用クラッチ８を締結することにより、パラレルハイブリッドモードによる走行も可能である。
　次に、実施形態１の作用効果を説明する。
　図２は、実施形態１の比較例であり、１軸（入力軸１ｂ）上に変速用クラッチ２０を配置して２段変速トランスミッションを構成したものである。
　ハイギヤ段用ギヤ列１２の駆動ギヤ１２ａ１およびローギヤ段用ギヤ列１３の駆動ギヤ１３ａ１は、入力軸１ｂ上に回転可能に支持された遊転歯車である。変速用クラッチ２０は、ドグクラッチであり、クランク軸１ａの軸線方向において、両駆動ギヤ１２ａ１，１３ａ１の間に配置されている。変速用クラッチ２０（のスリーブ）が左側締結位置（Ｌｅｆｔ）のとき、駆動ギヤ１２ａ１と入力軸１ｂとが連結されると共に、駆動ギヤ１３ａ１と入力軸１ｂとの連結が切り離され、ハイギヤ段となる。変速用クラッチ２０（のスリーブ）が右側締結位置（Ｒｉｇｈｔ）のとき、駆動ギヤ１３ａ１と入力軸１ｂとが連結されると共に、駆動ギヤ１２ａ１と入力軸１ｂとの連結が切り離され、ローギヤ段となる。変速用クラッチ２０（のスリーブ）が中央解放位置（Ｎ）のとき、駆動ギヤ１２ａ１と入力軸１ｂとの連結が切り離されると共に、駆動ギヤ１３ａ１と入力軸１ｂとの連結が切り離され、ニュートラル状態となる。
　入力軸１ｂには、発電用モータギヤ列７の駆動ギヤ７ａと噛み合うギヤ２１が固定されている。
　ハイギヤ段用ギヤ列１２の被動ギヤ１２ａ２およびローギヤ段用ギヤ列１３の被動ギヤ１３ａ２は、カウンタ軸１２ｂに固定されている。また、カウンタ軸１２ｂには、デファレンシャル１０のリングギヤ１０ａと噛み合うエンジン最終減速ギヤ２２が固定されている。
　エンジンの出力軸に直結するギヤを選択的に切り替えてハイロー２速のトランスミッションを構成するにあたり、比較例のように、１軸（入力軸１ｂ）上に変速用クラッチ２０を配置した場合、１軸上に２つの遊転歯車（両駆動ギヤ１２ａ１，１３ａ１）と変速用クラッチ２０（のスリーブ）が並ぶこととなる。さらに、入力軸１ｂ上には、エンジン１により発電用モータ２を常時駆動するためのギヤ２１を設ける必要がある。つまり、比較例では、１軸上に４要素が並ぶ４列配置となるため、クランク軸１ａの軸線方向における寸法が大型化し、車両搭載性の悪化を招く。
　これに対し、実施形態１の駆動装置では、変速用クラッチをハイ用クラッチ１４とロー用クラッチ１５として２軸（入力軸１ｂ、カウンタ軸１２ｂ）に分散させた。これにより、２つの駆動ギヤ１２ａ１，１３ａ１のうち、入力軸１ｂと固定された駆動ギヤ（実施形態１では駆動ギヤ１３ａ１）を、発電用モータ２を常時駆動するためのギヤとして利用できる。このため、入力軸１ｂ上およびカウンタ軸１２ｂ上に並ぶ要素はそれぞれ３つとなり、３列配置を実現できる。よって、４列配置となる比較例に対して、クランク軸１ａの軸線方向における寸法を小型化でき、車両搭載性を向上できる。なお、変速用クラッチを２軸に分散させているが、回転軸数は比較例と同数であるため、クランク軸１ａと直交する方向の寸法が大型化することはない。
　実施形態１の駆動装置では、ハイギヤ段用ギヤ列１２の被動ギヤ１２ａ２が、デファレンシャル１０のリングギヤ１０ａと噛み合う。つまり、被動ギヤ１２ａ２は、ハイ変速比用（２速用）のギヤ列の被動ギヤと、最終減速装置の減速小歯車とを兼ねる。ここで、仮に最終減速装置の減速小歯車を、被動ギヤ１２ａ２とは別に設けた場合、カウンタ軸１２ｂ上に４要素が並ぶこととなる。一方、被動ギヤ１２ａ２が減速小歯車を兼ねることにより、カウンタ軸１２ｂ上に並ぶ要素は３つとなり、クランク軸１ａの軸方向寸法における寸法を小型化できる。
　〔実施形態２〕
　実施形態２の基本的な構成は実施形態１と同じであるため、実施形態１と相違する部分のみ説明する。
　図３は、実施形態２の車両の駆動装置を示す概略図であり、実施形態２では、ギヤボックス４内において、発電用モータギヤ列７、ローギヤ段用ギヤ列１３および走行用モータ減速機構９が、モータ走行用クラッチ８、ハイ用クラッチ１４およびロー用クラッチ１５（の各スリープ）に対して左側に配置され、ハイギヤ段用ギヤ列１２およびデファレンシャル１０が、モータ走行用クラッチ８、ハイ用クラッチ１４およびロー用クラッチ１５（の各スリーブ）に対して右側に配置されている点で実施形態１と相違する。発電用モータ２および走行用モータ３は、ギヤボックス４の右側に配置されている。よって、実施形態２では、第１平面Ｐ１および第２平面Ｐ２の位置が実施形態１とは逆となり、右側から、第１平面Ｐ１、第３平面Ｐ３、第２直線Ｐ２の順に並ぶ。
　実施形態２においても、実施形態１と同様の作用効果を奏する。
　（他の実施形態）
　以上、本発明を実施するための形態を、実施形態に基づいて説明したが、本発明の具体的な構成は、実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲の設計変更等があっても本発明に含まれる。
　例えば、第１ギヤおよび第２ギヤをローギヤ段用ギヤ列とし、第３ギヤおよび第４ギヤをハイギヤ段用ギヤ列としてもよい。
