Abstract: A planetary carrier supports a geared rotor from an inside in a radial direction, and receives a radial load in a first region, which is offset to one end from a center position in an axial direction. A ball bearing roller supports the planetary carrier from an outside in the radial direction in a second region, which is offset to an other end from the center position. The ball bearing roller is a single-row ball bearing roller that has an outer ring supported by a drive rotor, an inner ring which supports the planetary carrier, and a plurality of rolling elements which are rotatably installed in a single row to be in contact with and between the outer and the inner rings. The geared rotor is tilted relative to the axial direction, and contacts a driven rotor in the axial direction. An angle of the geared rotor relative to the axial direction is set to be smaller than a maximum allowable angle at which the inner ring is allowed to be tilted relative to the axial direction.

Abstract: A control device for an internal combustion engine includes an intake-side variable valve timing mechanism and a controller. The intake-side variable valve timing mechanism is configured to continuously advance or retard a phase of a cam that actuates an intake valve. The controller is configured to actuate the intake-side variable valve timing mechanism toward a retardation side and position the intake-side variable valve timing mechanism at a prescribed position, and execute fail-safe control on the basis of a signal from a cam position sensor instead of a signal from the crank position sensor, when it is determined that there is a failure in a crank position sensor of the internal combustion engine.

Abstract: In a valve timing adjusting device, a second rotation body includes a second sun gear part provided inside of a first rotation body, and is connected to a drive shaft or a driven shaft through inside of the sprocket part to be rotated corresponding to the drive shaft or the driven shaft. When the second rotation body is brought into contact with the sprocket part, rotation of the second rotation body relative to the first rotation body is restricted. A planetary rotation body includes a first planetary gear part engaged with the first sun gear part, and a second planetary gear part engaged with the second sun gear part. The planetary rotation body makes a sun-and-planet motion inward of the first sun gear part and the second sun gear part to change a phase of the relative rotation between the first rotation body and the second rotation body.

Abstract: An engine is provided with a variable valve timing device which transmits a rotational force generated by a motor via a motor drive circuit to a cam shaft so as to change a rotational phase of the cam shaft relative to a crank shaft. An ECU cools a motor and a motor drive circuit when the change of the rotational phase stops during the changing of the rotational phase of the cam shaft to a target value is detected. In addition, the lock state is eliminated by driving the motor by the motor drive circuit after cooling the motor device.
