    Abstract: A parking device includes a parking gear, a parking pawl, and a torsion spring. The parking gear is directly coupled to an axle. The parking pawl is pivotably supported by a fulcrum pin and provided with a claw configured to be able to mesh with a tooth space of the parking gear. The torsion spring is fitted on the fulcrum pin, with a first end of the torsion spring mounted on the parking pawl and a second end of the torsion spring mounted on a holding member that holds the fulcrum pin.

    Abstract: A vehicle drive device includes: an oil pump; an oil cooler; a bypass oil passage configured to bypass the oil cooler; a control valve; and a control unit. The control unit keeps the control valve in a first state while a temperature of oil circulated by the oil pump is lower than a predetermined value, and switches the control valve to a second state when the temperature of the oil circulated by the oil pump becomes not lower than the predetermined value while the control valve is in the first state. The control unit changes a voltage command value of an electric motor to a value smaller than a voltage command value corresponding to a required output of the electric motor after elapse of a predetermined period from a time the control valve is switched to the second state.

    Abstract translation: 车辆驱动装置包括：油泵; 油冷却器 旁路油路构造成绕过油冷却器; 一个控制阀; 和控制单元。 当由油泵循环的油温度低于预定值时，控制单元将控制阀保持在第一状态，并且当由油泵循环的油的温度变为不是时将控制阀切换到第二状态 在控制阀处于第一状态时低于预定值。 控制单元在从控制阀切换到第二状态之后的预定时间段之后，将电动机的电压指令值改变为小于对应于电动机的所需输出的电压指令值的值。
