To fix a TV (electrical apparatus mounted) having a power cord (insulated electric wire) to a DVD player (mounting body) when the TV is mounted on the DVD player, the DVD player is provided with a main body (a part of a main body) and a hook member fixed to the main body. The position on the main body at which the hook member is fixed is changeable, and the cord is securely wound around the hook member. This arrangement is convenient, eliminating the necessity of separately preparing a member such as a belt, while enabling to easily and securely fix, to a mounting body, various types of TVs having respective attaching positions where an insulated electric wire is attached, to effectively prevent the TV from falling down in the event of an accident such as an earthquake.
