<p><P>PROBLEM TO BE SOLVED: To suppress lowering of acceleration caused in gear shifting or the like without contributing to rotation fluctuation in low-speed rotation. <P>SOLUTION: A planet gear unit 21 is provided on an output side of an engine 11, and either of a ring gear 211, a pinion gear 212, and a sun gear 213 is connected to an input shaft of the unit 21, and any one of other gears is connected to an output shaft. The planet gear unit 21 includes a clutch 215 structured so as to connect at least two of the three gears 211-213 for forming the planet gear, and a brake 214 for restricting rotation of a third gear except for the two gears connected to the input shaft and the output shaft, and a rotating mass 216 for generating predetermined inertia moment is coupled to the third gear. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
