PURPOSE:To enable secure charging by preventing a defect in charging caused by electric corrosion. CONSTITUTION:A couple of opening parts 7 are formed at the frame-shaped projection part 3 of a charging base 1. A charging terminal 11 formed of a columnar body having a projection 13 on the outer peripheral surface is supported rotatably at the tip part of a support plate 8 made of a leaf spring fitted in the charging base 1 and part of the outer periphery is projected from the cylindrical body 7 into a recessed part 5. A couple of opening parts 14 are formed on the wall surface of the transmission part 4 of a handset 2. A charging terminal 15 formed of a columnar body having many projections 17 on the outer peripheral surface is supported rotatably and part of the outer periphery is projected outward from the opening parts 14. Each time the handset 2 is set on the charging base 1, the charging terminals 11 and 15 are rotated in contact with each other while pressed, and charging is carried out at different contact position at all times. The charging terminals 11 and 15 are provided with the projections 13 and 17 and then the contact pressure per unit area is increased to obtain stable contact. |
