Abstract: A manufacturing method for a hydroelectric power generation system includes removing a transaxle including a first motor generator from an end-of-life hybrid electric vehicle, and assembling a hydraulic turbine to a rotary shaft coupled to the first motor generator in the removed transaxle. The rotary shaft to which the hydraulic turbine is assembled may be an engine shaft connected to an engine of the hybrid electric vehicle when the transaxle is mounted on the hybrid electric vehicle.

Abstract: Since one end of a spring is received by a planar portion of a spring seat provided on any one of an outer plate and an inner plate, it is possible to support the spring with a planar member without machining a bottom wall face of the outer plate into a planar shape. Since the spring seat has seat guide portions that contact the outer plate, it is possible to suppress the fluctuation of the spring seat and the fluctuation of the spring by the seat guide portions, so it is possible to reliably prevent interference of the spring with its peripheral portion. Therefore, a load on the spring is reduced, so it is possible to improve the durability of a one-way clutch.

Abstract: A control device for a hybrid vehicle includes a rotation detector and electronic control unit. The rotation detector is configured to detect a rotational state of the third rotational element of the hybrid vehicle. The electronic control unit is configured to control a first motor generator of the hybrid vehicle such that output torque of the first motor generator becomes zero when the electronic control unit determines, based on the rotational state of the third rotational element, that the third rotational element has a rotational fluctuation while the hybrid vehicle is travelling in a dual drive motor travelling mode. The dual drive motor travelling mode is a mode in which the hybrid vehicle travels while both the first motor generator and a second motor generator serve as driving force sources for travelling in a state where a first rotational element is fixed by a lock mechanism.

Abstract: A reservoir device is provided, which prevents water from flooding in an accumulation tank and improves on-vehicle installation capability. The reservoir device 10 includes a catch tank 13 connected to an airspace “A” formed above an oil surface of working oil accumulated in an accumulation tank 12, which has a bottom surface formed with an external-air communication aperture 32. Liquid entering from the external-air communication aperture 32 is allowed, to be accumulated in the catch tank 13 once, and then is suitably discharged through the external-air communication aperture 32. This precludes the accumulation tank 12 from flooding with water and improves on-vehicle installation capability.
