Abstract

PROBLEM TO BE SOLVED: To prevent output cords from tangling even when the power supply adapter is piled up or horizontally aligned together with other power supply adapters to be stored, by providing a winding part wound with the output cord from the power supply adapter, and a fixing part fixing an output plug from the power supply adapter. SOLUTION: Side surfaces 4 and a corner part 5 of a power adapter body 3 are provided with a winding part 1 such as a notch 6, etc., wound with an output cord 10 from the power supply adapter, and a fixing part 2 such as a socket 7, etc., fixing an output plug 11 from the power supply adapter. This suppresses protrusion of the output cord 10 of the power supply adapter from the winding portion and prevents it from tangling, to improve the working environment. Further, the interval at which the power supply adapters are piled up or horizontally aligned to be stored is narrowed, which can lessen the area for the storage. In addition, the surface area of the power supply adapter is enlarged by the shape of the notch 6 portion, to enhance heat radiation of the power supply adapter, thus the life of the power supply adapter can be lengthened.
