とを特徴とする。According to a first aspect of the present invention, there is provided a non-contact power feeding device, in which a feed line is laid so that a forward path and a return path are substantially parallel to each other, and two legs are connected to each other. A pickup having a coil connected to a load to be fed to a U-shaped core having a connecting portion, wherein the feeding line is positioned between the legs in a non-contact state.

漏れ磁束が小さくなるため、損失（誘導損）が減る。In the first aspect of the invention, each pickup has two legs, and when each leg has a thickness (length of the legs in the juxtaposed direction) d, one of the pickups Since the legs are separated from each other at the same position in the juxtaposed direction of the forward and return paths of the power supply line, that is, the legs are seen to overlap when viewed in the longitudinal direction of the power supply line, When viewed from the front of the two pickups respectively arranged on the return path and the return path (when viewed from the longitudinal direction of the power supply line), the pickup has an E-shape having a leg portion having a thickness d at both ends and the center of the connecting portion. Is smaller than the conventional E-shaped pickup having leg portions having a thickness d at both ends of the connecting portion and having a leg portion having a thickness 2d at the center. Therefore, the center-to-center distance between the outward path and the return path of the power supply line can be reduced. In addition, since the center distance between the forward and return paths of the power supply line can be reduced, the inductance of the power supply line can be reduced to improve power supply efficiency, and the leakage magnetic flux can be suppressed to reduce the influence of magnetic fields on peripheral devices. Can be suppressed. Moreover, since the leakage magnetic flux to the periphery of the power supply line is reduced, the loss (induction loss) is reduced.

往路と復路との中心間距離を減少させることができる。Further, since the inductance of the power supply line can be reduced, the line length of the power supply line can be increased, the current of the power supply line can be increased, or the power supply can be downsized.
Further, since the magnetic flux generated on the outward path and the magnetic flux generated on the return path pass through different leg portions, the magnetic flux density does not increase inside the same leg portion. Therefore, the center-to-center distance between the forward path and the return path of the power feeding line can be reduced without deteriorating the power feeding efficiency of the contactless power feeding device.

記Ｅ字状のピックアップより小さくできる。Further, since it is not necessary to reduce the distance between the pickup and the power supply line, it is possible to prevent the pickup and the power supply line from coming into contact with each other. Further, since the two pickups are arranged so as to be overlapped when the legs are viewed in the longitudinal direction of the power supply line, the forward path and the return path are separated from each other, so that the directions of the magnetic flux leaking from the respective pickups are opposite to each other. And the magnetic fluxes weaken each other. Therefore, the influence of the magnetic field on the peripheral device can be suppressed. Furthermore,
The cross-sectional shape of the pickup viewed from the longitudinal direction of the power supply line can be made smaller than that of the E-shaped pickup.

In the second invention, by shortening the distance between the pair of arranged pickups, it is possible to weaken the leakage magnetic fluxes from the respective pickups and suppress the influence of the magnetic field on the surroundings. 2 pickups should be placed
If the distance between two locations is large and the influence of the magnetic field on the surroundings increases by arranging each pickup of the pair of pickups at each location, use two pairs of pickups, and use a pair of pickups at each location. By arranging them, and at this time, by reducing the distance between the pickups of each set, the influence of the magnetic field on the surroundings can be suppressed.

In a transport vehicle including a motor and a plurality of wheels driven by the motor, a plurality of the pickups are provided,
The respective pickups are spaced apart from each other, and one set of pickups is characterized in that only one of the leg portions is arranged at the same position in one direction. According to the third invention, since the pickup used in the non-contact power feeding device according to the first invention or the second invention is provided, for example, the driving power can be obtained by bringing the pickup close to the power feeding line. Moreover, the effect of the contactless power supply device can be obtained. Further, since the pickup can reduce the center-to-center distance between the outward path and the return path of the power supply line, the influence of the magnetic field on the periphery of the vehicle body can be suppressed.

Since the weight of No. 4 is added, the weight balance of the vehicle body can be improved, and the same effects as those of the first embodiment can be obtained.

間距離を減少させることができる。According to the non-contact power supply device of the present invention, a pair of U-shaped pickups are paired on the forward path and the return path of the power supply line so that one leg portion thereof overlaps with the longitudinal direction of the power supply line. Thus, each pickup has two legs, and when each leg has a thickness d, one leg of each pickup is connected to the forward path and the return path of the power supply line. Since the legs are spaced apart from each other at the same position in the juxtaposed direction, that is, the legs are seen to overlap when viewed in the longitudinal direction of the power supply line, they are arranged on the outward route and the return route respectively.
A front view of the two pickups has an E shape having a leg portion having a thickness d at both ends and the center of the connecting portion. The pickup has a conventional leg portion having a thickness d at both ends of the connecting portion. The thickness d is smaller than that of an E-shaped pickup having a leg portion having a thickness of 2d at the center, and the center distance between the forward path and the return path of the power supply line can be reduced.

Loss (induction loss) is reduced because the leakage flux around the power supply line is reduced. Further, since the inductance of the power supply line can be reduced, it is possible to increase the line length of the power supply line, increase the current of the power supply line, or downsize the power supply.

Therefore, the center-to-center distance between the forward path and the return path of the power feeding line can be reduced without deteriorating the power feeding efficiency of the contactless power feeding device. Further, since it is not necessary to reduce the distance between the pickup and the power supply line, it is possible to prevent the pickup and the power supply line from coming into contact with each other. Furthermore, the cross-sectional shape of the pickup when viewed in the longitudinal direction of the feeder line can be made smaller than that of the E-shaped pickup.

For example, when the distance between two places where a pair of pickups should be arranged is large and the influence of a magnetic field on the surroundings increases by arranging each pickup of a pair of pickups at each place, use two pairs of pickups. By arranging a pair of pickups at each location and reducing the distance between the pair of pickups at this time, the influence of the magnetic field on the surroundings can be suppressed more than when only one pair of pickups are arranged.

Since the pickup used in the non-contact power feeding device described in 2 is provided, driving power can be obtained by bringing the pickup close to the power feeding line,
Moreover, the effect of the non-contact power supply device can be obtained.
Further, since the pickup can reduce the center-to-center distance between the outward path and the return path of the power supply line, the influence of the magnetic field on the periphery of the vehicle body can be suppressed. Further, by disposing the pickups near the front wheels and near the rear wheels, respectively, the weights of the pickups are added to the front wheels and the rear wheels, respectively, so that the weight balance of the vehicle body can be improved.
