ABSTRACT:
A structure for accommodating an electric apparatus having contacts in an accommodating space formed by joining a welding protrusion of a first member and a joint portion of a second member by ultrasonic welding. A groove is formed between the joint portion and the accommodating space to gather and prevent welding refuse produced by the ultrasonic welding from penetrating into the accommodating structure and sticking to the contacts of the electric apparatus and to concentrate ultrasonic energy to the joint portion. An opening through which the welding refuse flows is also formed outside of the joint portion. The opening has an aperture that increases with increasing distance from the joint portion.
