Abstract:
1. A transmission comprising: a first gear element pair and a second gear element pair which are at least two sets of gear element pairs, the first gear element pair and the second gear element pair are respectively arranged between an input member and an output member supported rotatably; a first clutch and a second clutch which are at least two sets of clutches, the first clutch and the second clutch respectively couple at least two sets of the gear element pairs releasably between the input member and the output member; at least one set of a non-circular gear element pair which is arranged between the input member and the output member; and at least one set of a non-circular gear element pair-use clutch that couples at least one set of the non-circular gear element pair releasably between the input member and the output member, wherein the non-circular gear element pair includes a first meshing section in which a reduction ratio between the input member and the output member becomes equal to a first reduction ratio in at least a partial meshing section of the first gear element pair when the first gear element pair is coupled between the input member and the output member, and a second meshing section in which a reduction ratio between the input member and the output member becomes equal to a second reduction ratio in at least a partial meshing section of the second gear element pair when the second gear element pair is coupled between the input member and the output member.
