A contactless power transferring apparatus comprising: a terminal loading portion which has an opening of a size that is at least larger than an outer form of a mobile terminal and which is configured to receive a mobile terminal; a primary coil that is disposed with a coil surface thereof substantially in parallel with a wall surface of the terminal loading portion and is configured to transfer power using electromagnetic induction to a secondary coil incorporated in the received mobile terminal; an up-down-direction pressing portion operable when the mobile terminal is inserted inside the terminal loading portion, to operate in an up-down direction that is a mobile-terminal loading and removing direction so as to press and support a case base surface of the mobile terminal from below and position the primary coil and the secondary coil of the mobile terminal in the up-down direction; a width direction pressing portion (21a, 21b) operable when the mobile terminal is inserted inside the terminal loading portion, to operate in a width direction of the mobile terminal so as to press and support the mobile terminal from the width direction and position the primary coil and the secondary coil of the mobile terminal in a left-right direction; a thickness direction pressing portion operable when the mobile terminal is inserted inside the terminal loading portion, to operate in a thickness direction of the mobile terminal so as to press and support the mobile terminal from the thickness direction and dispose the primary coil and the secondary coil of the mobile terminal a predetermined distance apart; and an apparatus-side positioning portion that is disposed at a predetermined position relative to the primary coil and operable when the mobile terminal is loaded inside the terminal loading portion, to align center positions of the primary coil and the secondary coil by engaging a terminal-side positioning portion disposed at a predetermined position relative to the secondary coil of the mobile terminal. a terminal loading portion which has an opening of a size that is at least larger than an outer form of a mobile terminal and which is configured to receive a mobile terminal; a primary coil that is disposed with a coil surface thereof substantially in parallel with a wall surface of the terminal loading portion and is configured to transfer power using electromagnetic induction to a secondary coil incorporated in the received mobile terminal; an up-down-direction pressing portion operable when the mobile terminal is inserted inside the terminal loading portion, to operate in an up-down direction that is a mobile-terminal loading and removing direction so as to press and support a case base surface of the mobile terminal from below and position the primary coil and the secondary coil of the mobile terminal in the up-down direction; a width direction pressing portion (21a, 21b) operable when the mobile terminal is inserted inside the terminal loading portion, to operate in a width direction of the mobile terminal so as to press and support the mobile terminal from the width direction and position the primary coil and the secondary coil of the mobile terminal in a left-right direction; a thickness direction pressing portion operable when the mobile terminal is inserted inside the terminal loading portion, to operate in a thickness direction of the mobile terminal so as to press and support the mobile terminal from the thickness direction and dispose the primary coil and the secondary coil of the mobile terminal a predetermined distance apart; and an apparatus-side positioning portion that is disposed at a predetermined position relative to the primary coil and operable when the mobile terminal is loaded inside the terminal loading portion, to align center positions of the primary coil and the secondary coil by engaging a terminal-side positioning portion disposed at a predetermined position relative to the secondary coil of the mobile terminal.
