Abstract

The convenience of operation is improved and the occurrence of connection failure between a connection-target terminal of an electric appliance and a connection terminal is reduced without requiring a complicated arrangement such as a fitting structure. A microphone charging device has a dustproof shutter provided so as to be movable with a microphone device setting/drawing-off operation between a covering position covering a charging terminal portion and an exposure position exposing the charging terminal portion, a torsion spring applies a fundamental urging force to the shutter between the covering position and exposure position, and plate springs apply additional urging force to the shutter in addition to the fundamental urging force in an additional urging section provided between the covering position and exposure position and thereby sets the shutter in an additionally urged state. When the shutter reaches the exposure position, the plate springs release the shutter from the additionally urged state.
