Abstract
A noncontact power transmission apparatus includes an instrument including a first case, a power reception coil arranged to generate an induced current due to magnetic flux in a first direction intersecting a gravitational direction, and a holder configured to hold the power reception coil at a predetermined distance from an outer surface of the first case in the first case. A power transmission device includes a conductive second case that has an opening into which the instrument is inserted in which the instrument is stored, a power transmission coil provided in the second case so as to generate magnetic flux in the first direction, and disposed to generate an induced current in the power reception coil, and an elastic body that is provided in the second case, maintains a distance between the power transmission coil and the power reception coil to be constant, and supports the power transmission coil.
