A planetary carrier Cf for a power division mechanism 3, which is provided in a power transmission system of a hybrid vehicle and linked to an input shaft 21 of an engine 1, includes stepped pinion gears each including a main pinion gear section Pf1 and a subpinion gear section Pf2. The main pinion gear sections Pf1 mesh with a sun gear Sf and a ring gear Rf of the power division mechanism 3. The subpinion gear sections Pf2 mesh with a ring gear R2 coupled to a drive shaft 91 of an oil pump 9. The oil pump 9 is thereby driven not only in HV travel and P charging during which the engine 1 is running, but also in EV travel. |
