A vehicle hydraulic device is provided with an electric motor-driven oil pump and a shuttle valve, so that a vane pump operates smoothly, even at the start, with a backpressure applied from the electric motor-driven oil pump to the vanes. Even when the oil pressure of a working fluid discharged from the vane pump exceeds the backpressure inside vane housing grooves, the working fluid flows from a vane pump discharge oil passage to a backpressure oil passage, so that the vanes are not pushed into the housing grooves. Thus, it is possible to reduce the fluctuations in discharge amount of the vane pump due to fluctuations in oil pressure of the vane pump discharge oil passage during operation of the vane pump.

A check valve provided makes it possible to operate a vane pump smoothly even at the start of the vane pump by maintaining an oil pressure in backpressure oil passages inside the vane pump while the vane pump is stopped. The check valve opens at the point in time when an oil pressure control device, to which a working fluid is supplied from the vane pump, has been filled with the working fluid and the oil pressure in discharge oil passages communicating with the oil pressure control device has risen and exceeded the oil pressure in the backpressure oil passages. Thus, the check valve is prevented from opening and closing repeatedly, so that the durability of the check valve is improved.

A stator assembling method for mounting a plurality of concentrically wound coils to an annular stator core, each of the concentrically wound coils being formed by winding a conductive wire for a plurality of turns, each of the concentrically wound coils having planned slot accommodation portions and planned coil end portions, the annular stator core having slots formed between adjacent teeth extending from a back yoke to a radially inner side, a spacing between the slots being widened toward a radially outer side. The stator assembling method includes the step of forming a coil assembly in which the plurality of the concentrically wound coils are disposed annularly and the step of pushing the coil assembly disposed in a space on an inner diameter side of the stator core to an outer diameter side and inserting the plurality of the concentrically wound coils into the slots of the stator core, in which each of the plurality of the concentrically wound coils has vertexes oriented outward in a axial direction in the planned coil end portions, and a distance in the axial direction between the vertexes of the planned coil end portions on both sides in the axial direction of each of the plurality of concentrically wound coils is gradually reduced toward the conductive wire mounted on the inner diameter side of the stator core from the conductive wire mounted on the outer diameter side of the stator core.

Flange portions 11f, 12f of a first case portion 11 and a second case portion 12 are fastened together to form a joint flange portion 15, whereby the first case portion 11 and the second case portion 12 form a drive device case 10. A rotating electrical machine control device 70 fixed to the outside of the drive device case 10 has a wide component 3 and a narrow component 5 having a smaller length in the axial direction X than the wide component 3. The narrow component 5 and the wide component 3 are arranged so as to overlap each other as viewed in a specific radial direction YS and such that the narrow component 5 is located on the radially inner side Y1 of the wide component 3. The narrow component 5 is disposed so as not to overlap the joint flange portion 15 as viewed in the specific radial direction YS but to overlap the joint flange portion 15 as viewed in the axial direction X. The wide component 3 is disposed so as to overlap the joint flange portion 15 as viewed in the specific radial direction YS but not to overlap the joint flange portion 15 as viewed in the axial direction X.

A hydraulic control device includes a first solenoid valve (SLG) capable of supplying an engagement pressure (PSLG), and a switching valve (27) capable of supplying the engagement pressure (PSLG), which is supplied from the first solenoid valve (SLG), switchably to one of a synchronization mechanism (S1) and an engagement element (B1, C1, C2). Thus, the first solenoid valve (SLG) can be commonly used for the synchronization mechanism (S1) and the engagement element (B1, C1, C2) as the source of supply of the engagement pressure (PSLG).

A lead wire bending process inserts a plurality of concentrically wound coils into slots, each of the concentrically wound coils being formed by winding a flat conductive wire for a plurality of turns, each of the slots being formed between every two adjacent teeth extending radially inward from an annular back yoke of a stator core, and bends lead wire portions of the inserted concentrically wound coils projecting in an axial direction from an end surface of the stator core. The lead wire bending process includes a first bending process of bending the lead wire portions using predetermined parts as fulcrums so that the parts positioned closer to ends than the predetermined parts topple radially outward and a second bending process of bending the lead wire portions using, as fulcrums, the connection parts connecting to the slot accommodation portions of the concentrically wound coils so that the lead wire portions approach the end surface of the stator core along the circumferential direction of the stator core after the bending in the first bending process.

There is provided a control device (5) for an automatic transmission (4) capable of outputting a torque reduction signal (Str) for reducing the driving torque of a driving source (2) during a transmission shift, in which, when a shift signal (Ss) for an upshift is input with an accelerator opening equal to or more than a threshold and a transmission shift is performed, the torque reduction signal (Str) for reducing the driving torque of the driving source (2) is output so that an inertial torque acting on an input shaft (41a) of a continuously variable transmission mechanism (41) is canceled while a transmission shift ratio is changed and, before the transmission shift ends, a vehicle driving force is reduced to a vehicle driving force after the transmission shift.
