Contactless power transmission device and contactless power transmission/reception apparatus

A contactless power transmission/reception apparatus comprising:

• a power reception device;
• and
• a power transmission device which transmits power to the power reception device in a contactless manner,
• wherein the power transmission device includes
• a shield case which has an opening portion at one end portion thereof, and into which the power reception device can be inserted through the opening portion,
• a power transmission circuit which is for transmitting power and is disposed to correspond to the shield case,
• a power transmission coil which is disposed on the inner side in the shield case when viewed from the opening portion, and transmits AC power from the power transmission circuit to the power reception device, and
• a notch which is formed on side surfaces of the shield case, from the opening portion toward the inner side such that both sides of a rear end portion of the power reception device inserted into the shield case can be held,
• wherein the power reception device includes
• a housing which can be accommodated in the shield case,
• a power reception coil which is disposed in the housing so as to face the power transmission coil when the housing is accommodated in the shield case, and receives AC power transmitted from the power transmission coil in a contactless manner, and
• a power reception circuit which is provided in the housing, and converts the AC power received by the power reception coil to DC power.
