Abstract: A cam guiding device includes a cam guide having a cylindrical portion, a partially cylindrical portion extending from a leading end portion of the cylindrical portion, a partially tapered portion extending from the leading end portion of the cylindrical portion, and a rotation stopper portion provided on the partially cylindrical portion, and a sleeve for accommodating the cam guide. The sleeve includes an arc portion that overlaps the partially cylindrical portion from an outside. A radius of the partially tapered portion increases as the partially tapered portion extends away from the cylindrical portion. The rotation stopper portion is a component that protrudes radially outward from an outer circumferential surface of the partially cylindrical portion. When the rotation stopper portion abuts the sleeve and an inner circumferential surface of the cam guide abuts the parking cam, rotation of the cam guide with respect to the sleeve is restricted.

Abstract: A mounting structure for a drive device includes: a power generation unit having an engine and a generator driven by the engine to generate electric power; and a drive unit having a motor for traveling and a power transmission mechanism that outputs torque from the motor toward a driving wheel. A frame member of a vehicle body is provided inside an engine compartment. The power generation unit and the drive unit are arranged, inside the engine compartment, side by side in a width direction of a vehicle so as not to contact each other, and are each connected to the frame member via a mount member. Portions of the power generation unit and the drive unit, which are close to each other in the width direction, are connected by a connecting member having an anti-vibration elastic body.

Abstract: A series hybrid drive unit that is downsized while improving power transmission efficiency. In the series hybrid drive unit, a generator is driven by an engine, and a motor is operated by electricity generated by the generator. Torque generated by the generator is delivered to drive wheels through a final reduction unit. An input member that is rotated by a torque of the engine, and that is arranged parallel to a rotational center axis Og of the generator. The generator and the motor are arranged parallel to each other while keeping a predetermined clearance, and the final reduction unit is arranged parallel to the motor. The input member and the generator are connected through a first wrapping transmission mechanism, and torque of the motor is transmitted to a final reduction unit through a second wrapping transmission mechanism.

Abstract: An electric motor includes a rotor shaft, and the rotor shaft has a shaft-core oil passage and radial oil passages. The shaft-core oil passage includes an inner wall facing radially inward. The radial oil passages are provided toward a radial outer side of the rotor shaft from the shaft-core oil passage. The radial oil passages penetrate through the rotor shaft. The radial oil passages have corresponding one of first connection openings connected to the shaft-core oil passage, so that oil that is not discharged from the first connection openings to the radial oil passage is supplied to other supply destinations. A distance of the first connection openings from the shaft core is shorter than a distance, from the shaft core, of that part of the inner wall which is not provided with the first connection openings.

Abstract: A first check valve of a hydraulic control system allows oil to flow in only a direction from a first oil pump toward an oil receiving portion. A second check valve allows oil to flow in only a direction from a second oil pump toward the oil receiving portion. A third oil passage is configured to provide communication between a merging point of a first oil passage and a second oil passage, and the second oil pump by bypassing the second check valve. The third oil passage includes a throttle mechanism. The third oil passage is configured to restrict a flow rate of oil that is discharged from the second oil pump.
