PROBLEM TO BE SOLVED: To enable replacement of a relay smoothly without erroneous wiring by providing a plurality of partitioning boards for partitioning an accomodation case into a plurality of chambers, and a cover for covering upper surfaces of the chambers and adapted to be mounted/demounted to/from the case. SOLUTION: A plurality of chambers 3 are formed in an accomodation case 2 with longitudinal partitioning boards 4A and lateral partitioning boards 4B. The chamber 3 has an opening area so that a user can pick a closed end terminal to be accomodated therein. A relay terminal number mark is applied to the outer peripheral surface of the closed end terminal. The closed end terminals having different number marks are accomodated in the chambers 3 for every number marks, and they are stored in order of the numbers. Upon replacement of relay, a cover 5 is removed from the case 2, then the closed end terminal stored in the chamber 3 is taken out, and connection of wrapping wire and lead wiere is conducted. Accordingly, only the terminal having a requied relay terminal number mark can be used without a mistake, thereby preventing generation of erroneous relay wiring.
