Description
本発明の第1の実施の形態について、図1乃至図4を参照して説明する。なお、以下に説明する実施の形態は、本発明を実施する上での好適な具体例として示すものであり、技術的に好ましい種々の技術的事項を具体的に例示している部分もあるが、本発明の技術的範囲は、この具体的態様に限定されるものではない。
以上説明した第1の実施の形態によれば、第1の突片471の第1の背面471bが第2の受圧面472aよりも第1の多板クラッチ43側に位置し、第2の突片472の第2の背面472bが第1の受圧面471aよりも第2の多板クラッチ44側に位置しているので、第1の押圧機構45の押圧力が第1の突片471により受け止められて第2の多板クラッチ44にほとんど作用せず、第2の押圧機構46の押圧力が第2の突片472により受け止められて第1の多板クラッチ43にほとんど作用しない。これにより、左右の後輪103,104のそれぞれに配分される駆動力を高精度に制御することができる。
次に、第1の実施の形態の変形例について、図5を参照して説明する。本変形例は、第1の実施の形態のセンタープレート47の構成を変形したものである。
次に、本発明の第2の実施の形態について、図6及び図7を参照して説明する。
以上、本発明を実施の形態に基づいて説明したが、これらの実施の形態は特許請求の範囲に係る発明を限定するものではない。また、実施の形態の中で説明した特徴の組合せの全てが発明の課題を解決するための手段に必須であるとは限らない点に留意すべきである。
