Abstract: An apparatus for fabricating a laminated core includes a lower mold including a die including a die hole, an upper mold including a punch, a stripper plate operable to restrict upward and downward movements of a metal sheet at a lowest descending position during punching out of the metal sheet by the punch, an adhesive applicator included in the lower mold and operable to apply an adhesive onto a lower surface of the metal sheet, and a controller configured or programmed to control the stripper plate and the adhesive applicator. The controller is configured or programmed to include a movement controller to control upward and downward movements of the stripper plate, and an applicator controller to cause the adhesive applicator to apply the adhesive onto the lower surface of the metal sheet while the stripper plate is not located at the lowest descending position.

Abstract: A motor vehicle has a first power storage device 4, a second power storage device 5, a power converter 10, a first switch S3 connects the converter 10 to an inverter 2, not through the second power storage device 5, a second switch S4 connecting the power converter 10 and the inverter 2 via the second power storage device 5. A third switch S5 connects the second power storage device 5 and a ground.
During stopping and/or power driving of the motor 1, the first switch S3 is set to a connected state, the second switch S4 is set to a disconnected state, and the third switch S5 is set to a connected state. Thus, energy is supplied from the first power storage device 4 to the second power storage device 5 while an output voltage of the first power storage device 4 is stepped down.

Abstract: A clutch device includes a pressure plate movable toward or away from a clutch center and rotatable with respect to the clutch center. The pressure plate includes a flange extending radially outward from an outer circumferential edge of a body, pressure-side fitting teeth projecting in a first direction from a front surface of the flange, holding input-side rotating plates and output-side rotating plates, and circumferentially arranged, and a flange-side recessed portion recessed in the first direction from a back surface of the flange. As seen in an axial direction of an output shaft, the flange-side recessed portion at least partially overlaps one of the pressure-side fitting teeth.

Abstract: A clutch device includes a clutch center, and a pressure plate movable toward or away from the clutch center, rotatable relative to the clutch center, and operable to press input-side rotating plates and output-side rotating plates. The clutch center includes center-side fitting teeth holding the input-side rotating plates and the output-side rotating plates, projecting radially outward from an outer peripheral surface of an outer peripheral wall, and arranged in circumferential directions, and an oil channel in an end portion of at least one of the center-side fitting teeth in a second direction. The oil channel allows clutch oil flowing at least at an inner peripheral surface of the outer peripheral wall to be discharged to outside of the clutch center.

Abstract: A clutch device includes a pressure plate movable toward and away from a clutch center to press input-side rotating plates and output-side rotating plates. An oil flow hole is located in a spline groove to penetrate an outer peripheral wall of the clutch center, to enable clutch oil having flowed out of an output shaft to be discharged to outside of the clutch center, and located between an end of a center-side slipper cam surface in a second circumferential direction and a center-side cam hole located ahead, in the first circumferential direction, of the end in the second circumferential direction, in the circumferential directions. A through hole is located ahead, in the first circumferential direction, of the end of the center-side slipper cam surface in the first circumferential to guide clutch oil flowing outside the clutch center to the inside of the clutch center.

Abstract: A motor vehicle has a motor, an inverter, a first power storage device, with a large-capacity characteristic, a second power storage device, with a high-power characteristic, a power converter and a circuit. The power converter has a voltage step down function during power driving. In the circuit, the power converter is connected to the first power storage device and the second power storage device. Thus, the first power storage device and the second power storage device are parallel to each other. During the power driving of the motor, the power converter steps down an output voltage of the first power storage device to supply energy from the first power storage device and the second power storage device to the inverter.

Abstract: In a power transmission apparatus, a centrifugal clutch includes a holder, a press, and springs to urge masses from a radially outer position to a radially inner position. The masses are each housed in an associated one of housing portions arranged in a circumferential direction of the holder such that the masses are radially movable. More than one spring is provided in the circumferential direction between an inner peripheral wall surface of each of the housing portions and an associated one of the masses to urge the associated mass from the radially outer position to the radially inner position.

Abstract: A power transmission device has a first pressure member (5a), a second pressure member (5b) and a back-torque transmitting cam. The first pressure member (5a) presses the drive-side clutch plates (6) and the driven-side clutch plates (7) against each other. The second pressure member (5b) releases a press-contact force between the drive-side clutch plates (6) and the driven-side clutch plates (7). The back-torque transmitting cam moves the second pressure member (5b) relative to the first pressure member (5a) to keep pressing the drive-side clutch plates (6) and the driven-side clutch plates (7) against each other when a rotational force is input to the clutch member (4), via the output shaft (3), in a process where the weight member (8) moves from the radially-outer position to the radially-inner position and the first pressure member (5a) moves to follow the interlocking member (9).
