A contactless power feeding device comprising:
- a placement portion on which a plurality of carts, each of which including a device and a power receiving unit that receives power to be fed to the device, is placed in a state of being arranged in one direction;
- a power transmitting unit that is provided at each of a plurality of placement positions at which one of the plurality of carts is placed in the placement portion and transmits power to the power receiving unit of the one of the plurality of carts by contactless power feeding;
- a first lock unit that is provided at a first placement position of the plurality of placement positions at which a first cart is placed, the first cart being one of the plurality of carts arranged top in the one direction, the first lock unit being configured to lock forward movement of the first cart in the one direction;
- a second lock unit that is provided at a second placement position of the plurality of placement positions at which a next cart is placed, the next cart being next one of the plurality of carts following the first cart in the one direction, the second lock unit being configured to lock forward movement of the next cart in the one direction;
- and
- a control unit that controls an operation of the first lock unit and the second lock unit, wherein
- the control unit releases a locked state of the first lock unit while maintaining a locked state of the second lock unit to allow forward movement of the first cart when receiving a supply instruction to supply one of the plurality of carts placed in the placement portion.
