- ケーシングの上部に駆動部が搭載され、該駆動部により駆動される駆動軸が垂設され、該駆動軸の下端側に当該駆動軸と一体に回転可能な駆動ギアが配設され、前記ケーシングの下部に前記駆動ギアと連結されたクラッチ装置が配設され、該クラッチ装置にプロペラを駆動する出力軸が連結された船外機において、
前記クラッチ装置は、
前記プロペラを駆動する前記出力軸の周囲に回転自在に配置され、前記駆動部で駆動される前記駆動軸により常時反対方向に駆動される一対の前進ギア及び後退ギアと、
前記出力軸の周囲の前記前進ギアと前記後退ギアとの間に配置され、前記出力軸に対して軸方向に移動可能、且つ、周方向に回転不能なドッグギアとを備え、
前記前進ギア及び前記後退ギアの前記ドッグギアと対向する部位と、前記ドッグギアの前記前進ギア及び前記後退ギアとそれぞれ対向する部位とに設けられた噛合部に、それぞれ互いに嵌合可能な噛合凸部及び噛合凹部が複数設けられ、
前記ドッグギアが前記出力軸に対して一方の軸方向に移動させられて、前記複数の噛合凹部と前記複数の噛合凸部とが嵌合することにより、前記ドッグギアと前記前進ギア又は前記後退ギアの一方とが噛合し、前記出力軸が駆動されるように構成されており、
前記駆動軸は、前記出力軸側に固定された前記駆動ギアを回転させるものであり、
前記前進ギア及び前記後退ギアは、前記駆動ギアと常時噛合された入力ギアをそれぞれ備え、
前記噛合凸部及び前記噛合凹部は、前記入力ギアより径方向内側の範囲で、それぞれ周方向に7個以上10個以下配設され、該噛合凸部は該噛合凹部よりも周方向の長さが前記出力軸の軸中心角度で1度乃至12度小さくなるように形成されていることを特徴とする船外機。 - 前記前進ギアと前記ドッグギアとの前記各噛合部又は前記後退ギアと前記ドッグギアとの前記各噛合部では、前記駆動力伝達面の面積の合計がそれぞれ340mm2以上であることを特徴とする請求項1に記載の船外機。
- 前記前進ギアと前記ドッグギアとの前記各噛合部又は前記後退ギアと前記ドッグギアとの前記各噛合部では、前記各駆動力伝達面の外側端縁が、それぞれ前記出力軸の軸方向に対して直交方向に沿う直線状に形成され、
前記各噛合部の前記外側端縁の長さの合計がそれぞれ70mm以上であることを特徴とする請求項1又は2に記載の船外機。 - 前記前進ギアと前記ドッグギアとの前記各噛合部又は前記後退ギアと前記ドッグギアとの前記各噛合部では、少なくとも一方の前記噛合凹部に隣接する頂部に、他方の前記噛合凸部を該噛合凹部に案内するスロープが形成されていることを特徴とする請求項1乃至3の何れか一つに記載の船外機。
