Abstract

　簡単な構成で効率のよい産業車両用変速機を実現する。この変速機は、入力軸(２)と、それぞれ複数段の変速段を有する第１及び第２変速機構(３)，(４)と、第２変速機構(４)と、クラッチ機構(５)と、回転方向切換機構(６)と、出力軸(７)と、を備えている。クラッチ機構(５)は、第１及び第２変速機構(３)，(４)の入力側に配置され、前後進を切り換えるための前進用クラッチＦ及び後進用クラッチＲと、第１及び第２変速機構(３)，(４)のいずれにエンジン側からの回転を入力するかを選択するための第１及び第２スナップクラッチＳＣ(１)，ＳＣ(２)と、を含む。回転方向切換機構(６)は、前後進の切換に応じて、第１変速機構(３)又は第２変速機構(４)への入力回転方向を、前進用回転方向又は後進用回転方向に切り換えるための機構である。出力軸(７)は第１及び第２変速機構(３)，(４)からの回転が入力されて出力する。
