Abstract: A rotational translation unit includes a rotation portion that rotates relative to a housing upon receiving an input of torque output from a speed reducer, and a translation portion that moves relative to the housing in an axial direction according to rotation of the rotation portion relative to the housing. A clutch is provided between a first transmission portion and a second transmission portion that are rotatable relative to the housing, and the clutch allows transmission of the torque between the first transmission portion and the second transmission portion in an engaged state of the clutch, and interrupts the transmission of the torque between the first transmission portion and the second transmission portion in a disengaged state of the clutch. A return spring is capable of urging the rotational translation unit in a direction away from the clutch relative to the housing.

Abstract: Oil pressure is produced by an electrical pump during an engine operation is temporarily stopped according to an idling-stop function and respectively supplied to multiple electromagnetic valves. A command value for a drive current is supplied to each of a driver circuit in order to adjust the oil pressure to be outputted from the corresponding electromagnetic valve. Such adjusted oil pressure is applied to a corresponding gear-change element and an oil-pressure a detecting device detects the oil pressure applied to the gear-change element to obtain detection value for the oil pressure. A current-command characteristic for each of the electromagnetic valves is updated based on the command value of the drive current and the detection value of the oil pressure.

Abstract: A regulator is provided with a first pressure reducing valve, a second pressure reducing valve, and a load adjusting part. A gas fuel pressure in a fuel tank is reduced to 1.4 MPa from 20 MPa by the first pressure reducing valve, and then reduced to 0.2 to 0.65 MPa by the second pressure reducing valve. In the second pressure reducing valve, the pressure of the gas fuel is reduced to 0.2 to 0.65 MPa from 1.4 MPa, so that the resistive force of a second O-ring for sealing a first middle-pressure chamber and a second pressure chamber can be made smaller. A sliding resistance between a needle and the second O-ring is reduced. An electromagnetic attracting force generated by the load adjusting part can be made smaller. Electricity consumed by the load adjusting part can be reduced and the regulator can be made smaller.
